Although rarely a cause of severe systemic disease in otherwise healthy adults, HSV infection may be severe or even fatal in neonates and those who are immunocompromised.
The incidence of herpes infection has risen so rapidly largely because this is a silent pandemic. Unfortunately, the gold standard of laboratory diagnosis--the Western blot--is expensive and may be difficult to obtain.
In the past, primary care physicians who were not content to rely on cultures had to resort to one of several enzyme-linked immunosorbent assays (ELISAs), which--although approved by the U. At $15 to $30 per test, the new tests are roughly one-fifth the cost of the Western blot, and much faster and easier to administer. After HSV enters the mucosa or abraded skin, it replicates within epithelial cells, producing cell lysis and inducing a local inflammatory response that may be clinically apparent within two to 21 days. Typically, the lesions of true primary herpes begin as papules and progress to thin-walled vesicles on an inflamed base (Figure 2). For the majority of patients with genital herpes, recurrences represent only a nuisance, and episodic antiviral treatment is satisfactory. Asymptomatic shedding--an important contributor to HSV spread--is common in both sexes, particularly in the period immediately surrounding a symptomatic episode. While there is no cure for genital herpes at this time, we are fortunate in having a number of selective antiviral agents--acyclovir, famciclovir.
Topical antiviral agents are never indicated for the treatment of genital herpes when an effective oral agent is available.
Unfortunately, many physicians remain suspicious of chronic antiviral therapy, recalling the unacceptable toxicity that accompanied chronic use of vidarabine and other early examples of the class. Continuous use of either acyclovir or famciclovir has been shown to suppress both symptomatic and asymptomatic HSV shedding by 80% to 90%. In a dose-range study that compared valacyclovir, acyclovir, and placebo, 250 mg bid of valacyclovir was equivalent to 400 mg bid of acyclovir in reducing the frequency of recurrences.
It is important for physicians to emphasize that use of antivirals should not become an excuse to abandon safer sex practices. When counseling patients experiencing their first episode of genital herpes, a balance must be struck between reassurance that the disease is not going to cause serious harm and validation of the physical and psychological suffering that it can produce.
Patients who are experiencing a particularly severe primary episode need to be assured that it is likely to be a once-in-a-lifetime event, and that recurrences are often mild and transient. New classes of agents that show promise in the treatment of genital herpes include nucleoside analogs, antisense compounds, and agents that act on HSV envelope glycoproteins. Recent research on herpes vaccines has focused on development of viral subunit vaccines containing the immunogenic HSV glycoproteins gD and gB as well as vaccines containing replication-incompetent viruses.
In summary, there is no evidence that an established latent HSV infection can be reversed or diminished with any of the existing antiviral agents. Sacks SL et al: Patient-initiated, twice-daily oral famciclovir for early recurrent genital herpes. Spruance S et al: A large-scale, placebo-controlled, dose-ranging trial of peroral valacyclovir for episodic treatment of recurrent herpes genitalis.
Tyring SK et al: A randomized, placebo-controlled comparison of oral valacyclovir and acyclovir in immunocompetent patients with recurrent genital herpes infections.
These guidelines have been produced by considering available literature and by basing the recommendations on the available evidence, both local and international. Grade A:    Very strong evidenceBased on well-designed prospective randomised controlled clinical trials.
Grade B:    Fairly strong evidenceBased on evidence from case-control or cohort studies, or clinical trials lacking one or more of the above features. Grade C:    Weak evidence or firmly held opinionBased on published case reports, well-written reviews or consensus. Prescribe 48 x 400mg tablets for patients to be able to self-initiate treatment at onset of symptoms. Valaciclovir (Valtrex™) 500mg daily is listed for suppressive treatment of recurrent genital herpes, subject to a Special Authority restriction, in the pharmaceutical schedule.
Fact: Genital herpes is caused by both HSV-1 and HSV-2 although HSV-1 is less likely to cause recurrent symptoms. Fact: As HSV-1 and -2 have different natural histories, it is important to ask for specific typing (so patients can be better informed).
Serological testing can be used to diagnose genital herpes in the setting of an active genital ulcer.
Fact: All first episodes of genital herpes should be treated regardless of timing of onset of symptoms (see page ??). The purpose of this guideline is to dispel common misconceptions and hopefully improve current management of those with herpes infection.
Genital herpes is a common infection caused by Herpes Simplex Virus Type One (HSV-1) and Herpes Simplex Virus Type Two (HSV-2) and as many as one in five adults in New Zealand have genital herpes due to HSV-2. Laboratory confirmation of the diagnosis and typing, by HSV PCR or viral culture, is important, but should not delay treatment.
Oral antiviral treatment of the first clinical episode should always be offered regardless of the time of symptom onset.
Neonatal HSV infection is a rare but potentially fatal disease of babies, occurring within the first 4-6 weeks of life. Specialist advice on management should be sought for a woman with a history of genital herpes and active lesions at term and especially in the high risk situation of a first episode up to 6 weeks prior to delivery. As many as one in five adults have genital herpes due to HSV-2, but most will have asymptomatic or unrecognised disease. Genital herpes due to HSV-1 (through oral to genital transmission) has also become common; HSV-1 is a frequent cause of primary genital herpes.
The natural history of genital HSV-1 infection is towards significantly fewer clinically apparent recurrences and less subclinical shedding than HSV-2. Genital herpes is an infection caused by the herpes simplex virus (HSV) and, for practical purposes, encompasses lesions on the genitals and nearby areas (i.e. HSV-2 prevalence varies between countries, being higher in the USA than in Europe, Australia and New Zealand. HSV-1 seroprevalence studies cannot distinguish between oral and genital infection sites which makes it much more difficult to estimate the prevalence of genital HSV-1 infection. Like HSV-2, HSV-1 seroprevalence increases with increasing age and tends to be more common in women.
Note: Routine typing of isolates enhances a clinician’s ability to give prognostic information and optimal clinical care. Most infections are acquired from someone who is unaware they are infected, who may have mild or asymptomatic infection. Herpes simplex virus enters the body, either through a break in the skin or through mucous membranes, during direct contact with infected secretions or mucosal surfaces.
It is important to remember that not all first episodes of HSV-1 or HSV-2 represent a new or recently acquired infection. The virus is readily inactivated at room temperature and by drying; hence, non-contact forms of spread, for example via fomites (inanimate objects) are considered unlikely.
Nearly everyone, both men and women, with genital HSV-2 infection sheds virus from time-to-time without symptoms, which is why sexual transmission can occur during asymptomatic periods. The viral load threshold for transmission from an episode of asymptomatic shedding has not been established. Aciclovir, famciclovir and valaciclovir all suppress symptomatic and asymptomatic shedding by up to 80-95%.
People who do not acquire HSV-1 during childhood are at risk of HSV-1 at any site, including genital infection, during adulthood.
In most studies, pre-existing HSV-1 infection does not decrease the risk of HSV-2 infection, but prior HSV-1 means HSV-2 infection is more likely to be asymptomatic.17 If HSV-2 genital infection is acquired first, then a new HSV-1 genital infection does not affect the frequency of recurrences. For patients with active lesions, either culture or PCR (depending on local laboratory availability), but not serology, are the recommended diagnostic methods. Clinical diagnosis alone is insensitive and inaccurate, with a 20% false positive rate.17 Suspected genital herpes must be confirmed by appropriate laboratory tests. HSV DNA detection by polymerase chain reaction (PCR) increases HSV detection rates compared with virus culture.
The person ordering serology should be able to supply appropriate pre- and post-test counselling. The window period for antibodies developing following infection is usually 2-6 weeks, but may be longer (months).
Primary infection: Recently acquired infection with HSV-1 or HSV-2 with an absence of antibodies to either type on serological testing. Recurrence: Previously acquired HSV-1 or HSV-2 infection with antibodies to the same type on serological testing. The first clinical episode of genital HSV-1 or HSV-2 may, but does not always, reflect recent infection. Aciclovir prescriptions do not require specialist authorisation and the medication is available through any pharmacy. It is not necessary or desirable to attempt to cover all these issues at the initial clinical assessment. Similarly, a diagnosis of acute radiculitis (herpetic lumbosacral radiculoneuropathy or Elsberg syndrome) tends to be overlooked, yet may cause acute urinary retention, constipation and sacral neuralgia.
Sporadic herpes simplex encephalitis is an acute necrotising viral encephalitis that is more usually caused by primary infection with HSV-1. Examination should include inspection of the genital region; speculum examination should be considered, but may need to be delayed if discomfort is anticipated. Laboratory confirmation of the diagnosis is important, but should not delay the initiation of treatment. Therapy should be initiated regardless of how long the lesions have been present and before virological confirmation.
Lesions may not completely heal over during the course of drug treatment; similarly, mild neurological symptoms may not yet have fully resolved. Topical aciclovir creams are not recommended because they are less effective than oral aciclovir (see page ??). It is important to ensure that patients receive accurate up-to-date information about genital herpes. Social and psychological issues should be addressed both at the first appointment and at follow-up. Psychological impact of the disease on the patient and their relationships (particularly important in the long term). It may be appropriate to offer the opportunity for their partner to have questions answered as well. Practice nurses or nurses who have training in this area may also be a good source of counselling support.
At the initial visit, a follow-up appointment should be offered for 5-7 days later, to evaluate symptoms, their psychological status, complete a full STI screen if appropriate, discuss results and answer any questions they may have. For those choosing episodic antiviral therapy, this is more effective when patients start therapy themselves at the first signs of a recurrence. Recommendations on counselling and follow-up are based on internationally accepted standards of practice. There is effective oral antiviral treatment for frequent, severe or problematic genital herpes.
Management of recurrent herpes depends on whether there is prior virological confirmation of infection. Only 10-25% of persons who are HSV-2 seropositive report a diagnosis of genital herpes, which suggests that most have unrecognised symptomatic or completely asymptomatic infections.28 However, once told they are HSV-2 seropositive, more than 50% are able to identify clinically symptomatic recurrences that may have previously been thought to be due to other conditions. In straightforward cases with a prior laboratory-confirmed diagnosis, the clinical history is often the principal means of determining that the patient has a recurrent episode, but other genital conditions, e.g. The atypical or non-ulcerative presentations of genital herpes can mimic most genital diseases, hence the need to consider more than one diagnosis at any given time. All these examples serve to underpin the importance of taking a detailed history and thorough physical examination of the whole skin, including oral mucosa. All genital lesions not previously diagnosed should have a viral swab taken with an explanation to the patient why this has been done.
An option is to instruct patients how to take a swab themselves and deliver direct to the laboratory.
Herpes recurrent lesions can occur on the hands, arms, shoulders and other areas of the body, commonly around the buttocks; the diagnosis is often overlooked.
Lumbar sacral radiculopathy can recur, but usually with less severe symptoms than in primary infection. People with genital herpes may become anxious or depressed and this may unmask or amplify disorders such as phobias or obsessive-compulsive disorder.
Recommendations on education and counselling and follow-up are based on internationally accepted standards of practice.
Effective episodic treatment of recurrent herpes requires prompt initiation of therapy during the prodrome or within one day of symptom onset. Standard therapy in New Zealand for suppression of herpes recurrences is oral aciclovir 400mg twice daily.
Withdrawal of therapy should be for a sufficient length of time to establish whether the pattern of recurrence has changed, for example, a minimum of two recurrences or for 3 months. Valaciclovir (Valtrex™) is available for suppressive treatment of recurrent genital herpes, subject to a Special Authority restriction, for those with recurrences not responding to aciclovir. The aim of episodic treatment is to reduce symptoms and duration of viral shedding during recurrences, rather than reduce the frequency of recurrences. Effective episodic antiviral treatment of recurrent herpes requires initiation of therapy during the prodrome that precedes some outbreaks or within one day of lesion onset.29 30 Beyond this timeframe, there is no clear benefit, so it is important that a prescription is readily available. With long-term suppressive therapy it is strongly advisable to have virological confirmation of the diagnosis before commencing treatment. The duration of therapy should be negotiated between the patient and the clinician; however, a treatment period of a year is recommended with periodic reassessment.
Suppressive therapy does not alter the natural history of recurrences long term and it is common to have a recurrence soon after withdrawal of therapy. The use of intermittent suppressive therapy is also considered a point for negotiation with the patient. Topical aciclovir creams are less effective than oral aciclovir.38 Hence, use of topical treatment is not recommended. Evidence for other therapies (oral L-lysine, aspirin, liquorice root cream, lemon balm, aloe vera cream, etc.) is limited. Although rare in immunocompetent individuals, clinically refractory (large, severe and sometimes atypical) lesions due to genital HSV may occur in patients with severe immunodeficiency, including late stage HIV disease.
Neonatal HSV infection is a rare, but potentially fatal, disease of babies, occurring within the first 4-6 weeks of life.
Most neonatal HSV infections are acquired at birth, generally from mothers with an unrecognised genital herpes infection acquired during pregnancy.
All women should be asked by their primary caregiver at their first antenatal visit if they or their partner have ever had genital herpes and given information on the potential risks of transmission in pregnancy; this includes the risk of genital HSV-1 from oral-genital contact. Concerns around herpes infection during pregnancy tend to relate to the risk of neonatal infection. Neonatal herpes is a rare but potentially serious infection, which may be associated with significant morbidity and mortality. Primary maternal infection before the 20th week of pregnancy may be associated with miscarriage,42 and in the second and third trimesters may be associated with preterm delivery. Several factors influence the risk of a newborn acquiring HSV infection at the time of delivery, the most important of which is whether the mother has newly acquired vs recurrent genital disease.46,47 The greatest risk of perinatal transmission is when a previously seronegative woman has a primary first episode of genital herpes near or at the time of delivery.
Although reactivation of HSV-1 is less than common than that of HSV-2, there is evidence that the reactivated HSV-1 may be more readily transmitted to the neonate. Of infants with proven HSV infection, 80% have no documented history of herpes infection in either the mother or her partner.
There are no randomised controlled trials to guide optimal delivery management for pregnant women with genital herpes. However caesarean section is not completely protective, as transmission of infection has occurred occasionally in the presence of intact membranes. No definitive studies have been carried out on the relationship between the duration of rupture of membranes in the presence of clinical lesions and the transmission of HSV to the fetus. In the case of recurrent genital herpes, maternal antibodies are protective and it has been argued that the benefits of caesarean section are low in this group of women, even if lesions are present at the time of delivery.
However, there are theoretical concerns that maternal aciclovir therapy may suppress the production of neutralising antibodies to the immunogen, glycoprotein D, thus having an effect on passive immunity to the fetus, and may suppress rather than treat newborn infections, thus leading to a delay in presentation of neonatal disease. Management of the woman should be in keeping with her clinical condition, using aciclovir in standard doses as indicated (see page ??). Provided delivery does not ensue, the pregnancy should be managed expectantly and vaginal delivery anticipated.


For further management advice, see Management of Pregnant Women with Recurrent Genital Herpes, page ??. Note: The first clinical episode may not be due to a primary infection, as previous infection may not have been recognised. Delivery should be by caesarean section, particularly in those women infected within 6 weeks of delivery because of high rates of asymptomatic shedding of HSV and insufficient time for a complete antibody response between infection and delivery. If vaginal delivery is unavoidable, consider treatment of mother with aciclovir and request an urgent referral to a paediatrician experienced in HSV infection (see Neonatal HSV Infection, page ??). Herpes zoster is a contagious type of disease that involves the peripheral nervous system as caused by reactivation of the varicella-zoster virus. Sacks is Professor, Department of Pharmacology and Therapeutics, University of British Columbia Faculty of Medicine, and founder of Viridae Clinical Sciences Inc., Vancouver. The vast majority, perhaps 44 million, are infected with herpes simplex virus type 2 (HSV-2), but a rapidly growing minority--roughly four million--are infected with HSV type 1 (HSV-1) (Figure 1).
Seroprevalence was considerably higher among women than among men, and higher among African Americans than among other ethnic or racial groups. Moreover, the presence of herpes lesions has been shown to facilitate HIV transmission; a 10-city survey conducted in 1996 showed a 7% rate of HSV-HIV coinfection. Today, the infection is rampant not only in that age group but throughout our high schools as well, with the fastest increases occurring among white adolescents aged 12 to 19.
Many teenagers have grown up thinking that they can change partners indiscriminately as long as they use a condom. In the NHANES III study, nine of 10 HSV-positive subjects did not know that they were infected. Their role in STD clinics and other settings of high HSV prevalence, however, remains to be determined.
In patients with no preexisting antibody to either HSV-1 or HSV-2, such primary first episodes have a range of presentations, from asymptomatic to severe with systemic symptoms.
These break down to form ulcers and then dry to crusts and heal, leaving a faint discoloration. Once established in the host, HSV maintains lifelong latency in the sensory ganglia, from which it may periodically migrate back to the epithelium to cause recurrent infection. What is insufficiently appreciated, however, is that a large minority--perhaps 40%--experiences six or more recurrences a year, and fully half of that group experiences at least 10 a year.
Studies employing viral culture suggest that patients with genital herpes experience viral shedding on 1% to 5% of asymptomatic days. Treatment should be individualized to suit the patient's needs, with chronic suppressive therapy recommended if symptomatic episodes are frequent or especially bothersome, or if they cause significant psychosocial and obsessive sequelae. But years of experience with acyclovir and its successors have shown that these are benign drugs that should not be restricted to acute use in all but the most severely affected patients. The data suggested that a once-daily dose of 500 mg of valacyclovir was also effective in a carefully chosen subgroup of patients who had less than 10 recurrences a year while off therapy.
Condom use should remain consistent, and couples should be abstinent (even from oral-genital sex) during periods of active infection.
For example, a patient whose primary relationship has just ended may want to suspend antiviral therapy until sex is contemplated with another partner. The first physician contact can have lasting effects--patients often tell me that the diagnosing physician did not take adequate time to explain the natural history of the disease, failed to take a proper sexual history, or either exaggerated or understated the potential impact of recurrent episodes on social relationships and sexual function.
Those who are not already in stable relationships may avoid potential romantic situations out of fear of having to inform new partners about the risk of asymptomatic shedding.
There are exceptions, however, and it is unwise to assume that all is well simply because the patient is in a long-term relationship.
Regimens combining older agents that target viral DNA polymerase with immunomodulators or ribonucleotide reductase inhibitors are also in development. On the positive side, the existing drugs are safe and effective for symptom control, and drug resistance does not appear to be increasing even among immunocompromised hosts.
Approvals valid for 12 months where the patient has genital herpes with two or more breakthrough episodes in any 6 month period while treated with aciclovir 400mg twice daily. Approvals valid for 12 months where the treatment remains appropriate and the patient is benefiting from treatment.
Minor lesions are common; any recurring localised genital symptoms or lesions should be investigated as possible genital herpes.
For genital infections, this is usually during sexual contact, with HSV-2 commonly transmitted during vaginal or anal sex and HSV-1 commonly passed on through oral-genital sex. It may be a first clinically recognised episode of a previously unrecognised or asymptomatic infection acquired weeks, months or years previously. For a given individual it is impossible to be certain when asymptomatic viral shedding occurs, but it is important not to give the impression that people are infectious all the time. Transmission may occur whilst receiving oral sex from someone who has oral HSV-1, even if the source partner is asymptomatic.
Other antivirals may be similarly effective, but this has not been proven in clinical trials. Specificity of culture is virtually 100%, but sensitivity is highly dependent on the stage of the clinical lesions, with an isolation rate of over 90% from vesicular or pustular lesions, 70% from ulcerative lesions, but only 27% at the crusting stage.18 Delayed transport of the specimen to the laboratory may further reduce yield. This is largely because it avoids problems that may affect culture results such as inadequate quantity of specimen, bacterial contamination, and inadvertent inactivation of virus by sub-optimal handling and sample transport delays. However, a negative test result does not necessarily exclude HSV infection since all methods are dependent on adequate collection of the specimen and, for culture in particular, on correct specimen handling and prompt transportation to the laboratory. The aim is to collect any vesicular fluid that may be present and to collect virus-infected cells from the base of the lesion. If not, you may need to specify “for herpes simplex DNA” and offer clinical explanation as to why this is the preferred test over culture, e.g. A positive HSV-2 serology result may cause significant psychological morbidity (see page ??-??). If the blood test being done only tests for HSV-2 antibodies, a negative test does not rule out the possibility of the person having genital herpes caused by type 1. Because false negatives and false positives occur, the results have to be weighed together with the clinical presentation and patient’s history. HSV-1 is a common infection, usually acquired in childhood, and may be shed from the oropharynx by asymptomatic individuals. HSV-2 in a person with previous antibodies to HSV-1, but absence of antibodies to HSV-2 on serological testing.
May be a primary or non-primary or first recognised clinical expression of a previously acquired infection weeks, months or years before.
It may represent a primary HSV infection or a new non-primary infection or a recurrence of a previously asymptomatic infection (see Table 2 on page ??). Patients are often very unwell and therapy should be initiated regardless of how long the lesions have been present and before virological confirmation. However, initial symptoms of genital herpes may not be recognised or may not occur until months to years later.
Rapidly, pruritic erythematous plaques appear followed by a cluster of small vesicles that contain clear to cloudy fluid. Acute, generally benign, lymphocytic meningitis may occur; HSV-2 is associated with aseptic meningitis in up to 36% of adult women and 13% of men with primary HSV-2 infection. Referred pain can affect the saddle area distribution, S3 and 4, of the sacral nerve and the bladder detrusor muscle.
Early treatment with oral steroids is effective;24 the use of antiviral agents is less clear, but is still commonly recommended. Clinical features are often nonspecific, as is common with all forms of encephalitis, and include headache, signs of meningeal irritation, altered mental status, and seizures. Mild forms of this condition are common and present with mildly itchy, pink-red blotches, starting on the extremities. In most cases of disseminated infection, lesions are confined to the skin, but hepatitis, pneumonitis and other organ involvement may occur, with or without vesicular skin lesions. Clinical diagnosis is insensitive, for example, ulceration may be due to aphthous ulcers, Stevens Johnson syndrome, fixed drug eruption, self-inflicted (sometimes unknowingly) trauma and autoimmune blistering disease (rare).
Refer immunocompromised patients, or those with herpetic proctitis, to an appropriate specialist, e.g.
Valaciclovir and famciclovir are not subsidised, although this may change as and when generic formulations become available. Nonetheless, a further course of therapy is not usually indicated unless new lesions continue to appear. NZHF resources are available to assist patients and clinicians with education and counselling.
For most patients, one visit is insufficient to properly manage the impact of genital herpes. It should be noted that it might take longer than 5 days for skin lesions to heal completely. It is suggested that either a minimum of two recurrences or approximately 3 months without suppressive therapy is required to establish the pattern. Shared management is important for the patient to feel a measure of control; the clinician should aim to be the facilitator of education and treatment options. For example, lichen sclerosus results in increased skin fragility; because this condition is usually itchy, secondary scratching may cause superficial erosions and haemorrhagic bullae are not uncommon. Atypical presentation is not unusual and HSV should be considered in any recurrent intermittent inflammatory genital lesions regardless of appearances. Other causes of recurrent genital lesions should be considered, but in the event of continuing recurrent lesions and viral culture swabs remaining negative, PCR testing of lesions or type-specific herpes serology testing may aid diagnosis.
Recurrent, benign, aseptic meningitis, known as Mollaret’s meningitis, may occur with HSV-2. Sufficient quantities of medication should be prescribed with instructions to start treatment as soon as symptoms begin. The recommended period of treatment is 12 months, which may be repeated year-by-year, if necessary. In consultation with the patient, sufficient quantities of medication may be prescribed with instructions to start treatment as soon as symptoms begin.
Patients may wish to consider this as a useful adjunct to safer sex behaviour and the use of condoms for the prevention of genital herpes transmission. Patients who do not have virological confirmation of recurrences or who have complications or severe problems relating to their herpes should see a specialist.
Patients should be given a reasonable break from therapy to reassess their pattern of recurrence to determine whether it has reduced with time. The usual recommended dose of aciclovir may need to be altered if breakthrough episodes are confirmed; aciclovir has poor oral bioavailability and some patients require multiple doses throughout the day. It is helpful to anticipate this and to provide sufficient medication to allow prompt self-initiated treatment of any early recurrences. Aciclovir is well tolerated and safety and efficacy data are supportive of longer-term use.37 Neurotoxicity (lethargy, confusion, hallucinations and involuntary movements) has been reported in those with renal impairment. Practitioners should be aware that this type of therapy is an option, particularly for patients who are keen to avoid a recurrence during a specified period, e.g. Topical antiviral creams are available over the counter, but are no longer subsidised on the pharmaceutical schedule.
Disseminated maternal herpes in pregnancy (from genital or oro-labial infection) is rare, but may be life-threatening; viraemia in the mother during primary infection may result in neonatal multi-organ involvement with significant mortality.
About 90% of neonatal herpes infections are acquired during labour through direct contact with infected genital secretions. Rarely, primary maternal infection may result in disseminated infection of the fetus with skin lesions, chorioretinitis or microcephaly or hydrocephalus at birth.43 The long-term outlook for these infants is very poor. Under such circumstances the risk of neonatal HSV infection is 57%, while vertical transmission rates of 25% are found in those with a non-primary first episode (infection with one virus type in the presence of antibodies to the other virus type) near or at the time of delivery. Risk factors for neonatal HSV infection included first-episode infection, HSV-1 vs HSV-2 isolation at the time of labour, the use of invasive monitoring, premature delivery and young maternal age.
Previously, 4 hours has been suggested as a cut-off time beyond which caesarean section may be no longer beneficial.
In the absence of definitive data, it is recommended that prophylactic aciclovir from 36 weeks should be used selectively, rather than routinely offered, for women with a history of recurrent genital herpes, e.g.
A small study of plasma levels of aciclovir at delivery in women on suppressive aciclovir at a dosage of 400mg tds from 36 weeks showed that levels were often suboptimal despite good adherence. Continuous aciclovir in the last 4 weeks of pregnancy reduces the risk of both a clinical recurrence at term and delivery by caesarean section.
Type specific culture or PCR and serological testing in conjunction with clinical evaluation will help identify primary HSV in pregnancy. Did you understand that the majority of individuals who have genital or oral herpes are not aware of it?
Chronic suppressive therapy in patients with frequent recurrences reduces viral shedding and may reduce transmission.
HSV seroprevalence has risen sharply during the past decade despite a barrage of warnings aimed at preventing the spread of AIDS and other sexually transmitted diseases (STDs).
Seroconversion during pregnancy may also be hazardous to the fetus, particularly if it occurs in the last trimester. White adolescents are nearly five times more likely to have herpes today than they were in the 1970s. But sex with a condom--although much safer than without--does not provide total protection, especially against chronic viral infections that are easily transmitted through skin-to-skin contact. Although HSV culture is quite specific, sensitivity varies according to the stage of the lesion (wet, vesiculo-ulcerative lesions being the most likely to yield a positive result) as well as the experience of the physician, transport conditions to the laboratory, and culture techniques used.
Even the Western blot may provide a false-negative result if performed prematurely, since antibodies to HSV envelope glycoproteins do not fully emerge until three to four months after exposure. By making rapid testing available to large numbers of high-risk, asymptomatic patients, the new serologies are expected to increase utilization of antiviral therapy and could have a real impact on disease spread. However, most patients who present with first-episode HSV infection are already seropositive, having been exposed to one or both forms of the virus in the past, and their first episodes are generally milder than symptomatic primary episodes. Outbreaks are generally bilateral and may be associated with local erythema and swelling as well as itching, tingling, and burning. Between 60% and 90% of patients who have had symptomatic primary genital herpes are subject to these outbreaks.
The psychological ramifications can be significant for any patient with genital herpes, but frequent symptomatic recurrences can cause repeated physical discomfort and almost constant awareness of risk.
However, a recent crossover study of women with early recurrent genital herpes using a sensitive HSV-DNA PCR assay found viral shedding in the cervicovaginal or vulvar region on an average of 28% of asymptomatic days sampled. Acyclovir has the longest history and is the least expensive, but the two prodrugs, famciclovir and valacyclovir, have also been thoroughly studied and have significantly greater bioavailability (Figure 4).
Some patients may want the benefit of reduced asymptomatic viral shedding, even though suppressive therapy has not yet been shown to reduce transmission (studies are under way). Given the large number of patients who are subject to frequent recurrences and the propensity of HSV to be shed on a regular basis, I feel that chronic therapy is an option that has not been adequately explored.
And in a recently reported, randomized, double-blind, placebo-controlled trial involving 30 referral centers in Canada and Europe, median time to recurrence in patients treated with famciclovir (250 mg bid) was 222 to 336 days, compared to 47 days for placebo recipients.
Promotion of condom use may lead to greater patient selectivity in choosing sexual partners and increased dialogue with physicians concerning STDs in general. Although many experts suggest an initial regimen of six months to a year, there are no data suggesting that toxicity increases or efficacy decreases beyond that point. Or, if an uninfected partner has taken a job abroad and will return infrequently, episodic treatment or selected periods of abbreviated suppressive therapy may be preferred. Women who are pregnant or considering pregnancy should receive additional information concerning the risk of neonatal transmission and rationale for cesarean delivery if lesions are active. Partners who initially reject the patient can be reminded that, with 20% or more of sexually active persons currently infected, genital herpes is difficult to avoid.
Since first reported in 1982, acyclovir-resistant strains of HSV have remained stable in this group and have only rarely been identified in immunocompetent individuals.
Most neonatal HSV infections are acquired at birth, generally from mothers with an unrecognised first genital herpes infection acquired during pregnancy. Genital herpes may be due to HSV-1 (the usual cause of orolabial herpes) or HSV-2 (more commonly associated with genital lesions). That said, HSV-1 accounts for 35% of confirmed anogenital infections in Australia5 and similarly a Waikato-wide study found 30-40% of anogenital isolates are due to HSV-1 each year.6 In that study, HSV-1 accounted for 53% of positive isolates from under-25 year olds, 30% in the 25–35 year olds, and 26% from over-35 year olds. It is estimated that up to a third of persons who are HSV-1 antibody positive do not have a clinical diagnosis of oral herpes,13 but will still shed HSV-1 virus.14 It is generally accepted that prior orolabial HSV-1 infection protects an individual against genital HSV-1. Increasingly, PCR is being implemented as the preferred diagnostic method for genital herpes, particularly since the advent of commercially available real-time assays. It is important to be aware of locally available tests, as these may vary, so an appropriate sample is taken. Infection with HSV-1 does not necessarily imply sexual exposure, but genital infection with HSV-1 is increasingly common.


Probable genital HSV-2 infection because oral and other non-genital site infections are uncommon.
This is based on evidence that the virus is shed from the infected area for a median of 11 days, with systemic and local symptoms lasting 2-3 weeks if untreated.
If giving results over the phone, check the person is in an appropriate situation to receive the call. These vesicles rupture within 1-2 days to form painful, sloughy, shallow ulcers with irregular margins, which may become confluent.
Erectile dysfunction, dull or severe burning pain in the anogential region, loss of sensation and hypersensitivity can occur down the thighs and the lower legs. Because prompt treatment of HSV encephalitis may minimise residual neurologic damage and prevent death, early consideration of this diagnosis is important. Some of the skin patches take on the classical ‘target lesion’ appearance, with a pink-red ring around a pale centre. Patients can be advised to bathe herpetic lesions in salt water, and women advised to urinate in a warm bath or shower to help reduce pain. A range of printed materials can be downloaded from the NZHF website, or ordered (please refer to resources listed on inside front cover).
Counselling and advice often form the major part of a follow-up appointment and time should be allowed for this.
At all times this process should be one of negotiation with the patient, as the pattern and severity of recurrent episodes is unpredictable.
For example, recurrent ulceration may be due to aphthous ulcers, erytheme multiforme, fixed drug eruption, self-inflicted (sometimes unknowingly) trauma and autoimmune blistering disease (rare). Eczema and less commonly psoriasis complicated by scratching may cause superficial erosions. Any recurring lesion of 1-2mm in size, occurring in the same genital area, is strongly suggestive of HSV-2 infection. There is a significant false-negative rate in the laboratory tests for HSV, although this is less for PCR. Patients should be offered long-term suppressive antiviral management, which may need to be continued indefinitely. A range of printed materials can be downloaded from the NZHF website or ordered – please refer to resources listed on inside front cover – primary care practitioners should have access to these resources or be able to advise their patients on how to obtain them.
In general, assisting the patient to take responsibility for, and control of, their disease and its treatment will help the patient overcome some of the psychological difficulties. It is suggested that either a minimum of two recurrences or approximately 3 months without suppressive therapy is necessary to establish the new pattern. A minority with late intrauterine HSV infection will present at delivery with skin or eye lesions. All results should be discussed with an expert knowledgeable in interpreting these results and who is aware of the sensitivity and specificity of available testing methods. Simple, many oral or genital herpes contaminated people just don't have any herpes signs, others have some symptoms which are mild adequate to confuse them with a rash or a mosquito bite or anything that might cause, redness, swelling, itching, burning and blisters, and some may not even understand exactly what herpes signs are. That somebody does not acknowledge or have herpes symptoms does not imply they do not have it. The immunosuppressed or had previous exposure with chicken pox can experience this.The virus’ action can travel to spinal and cranial sensory ganglia and the posterior gray matter of the spinal cord.
First episodes of maternal HSV-2 infection have been associated with premature labor, intrauterine growth retardation, spontaneous abortion, and neonatal death. A man who has herpes lesions at the base of the penile shaft or on the scrotum places his partner at risk even if a condom is used.
They range from a generalized flu-like illness to neurologic manifestations such as aseptic meningitis, lymphadenopathy, skin edema, and transient autonomic neuropathy.
In patients with mild or atypical presentations, cultures often are negative, since HSV may be present at the nerve roots yet remain undetected in urine or cervical mucus.
The polymerase chain reaction (PCR) technique, which can detect viral DNA from lesions that are culture-negative, is too sensitive to reflect true reactivation and too costly for routine clinical use. A more reliable ELISA with a sensitivity of about 95% and specificity of 96% to 98% has been developed and is awaiting release.
However, their usefulness as a general screening tool for pregnant women and their partners is likely to be limited by an unacceptably high proportion of false-negative and -positive responses. Indeed, a significant proportion of first episodes are really recurrences that are reflected in mild symptoms and minimal systemic sequelae.
The mean annual rate of recurrence for patients with HSV-2 infection is four episodes but may eventually decrease in some patients. Episodic treatment of such cases involves 10 or 12 separate courses of medication, which may speed healing of individual outbreaks but is not preventive and has only a modest effect on viral shedding.
When the same specimens were evaluated by both methods, the rate of HSV detection by PCR was 3.5 times higher than by culture--suggesting that genital reactivation and shedding occur with greater frequency or longer duration than standard techniques demonstrate.
Furthermore, they are simpler to take as episodic treatment because only two daily doses are required, compared with the standard acyclovir regimen of five daily doses.
Suppressive therapy with any of the three agents is more effective than episodic therapy and generally well-tolerated. At six months, the proportion of patients remaining completely free of recurrences was approximately three times higher in the famciclovir group (79% to 86%) than in the placebo group (27%). However, practical serologic diagnosis will be a necessary component of prevention with this predominantly subclinical STD.
I therefore recommend interviewing patients every 12 to 18 months to determine the extent of therapeutic benefit, consider the individual's risk of future outbreaks, and decide whether continuation is warranted. In addition to loss of self-esteem, patients may experience unresolved anger at themselves and the source partner, become obsessed with implications of the diagnosis, or lapse into depression with each outbreak.
With each new sexual relationship, a woman's odds of acquiring HSV infection rise another 5% (risk is slightly lower in men because of reduced transmission efficiency). Consequently, until an effective vaccine or cure for HSV infection is found, episodic or suppressive antiviral therapy accompanied by patient counseling will remain the standard of care. For those choosing episodic antiviral therapy, it is more effective when patients start therapy themselves at the first signs of a recurrence; this requires anticipatory prescribing. It is a very common infection that is often under-recognised, as a person may be asymptomatic or have only very minor symptoms. Possible exceptions may be those infected simultaneously at more than one site or those with very recent HSV-1 infection who have not yet seroconverted. However, results depend on multiple factors, including the adequacy of the specimen, and a negative result may not exclude infection. However, stringent quality control is necessary because of potential contamination by ‘carryover’ DNA from other biological samples19 and local validation is recommended. Type specific tests are used in population surveys, but their diagnostic reliability in individual patients is still debated. The condition is usually self-limiting and tends to resolve in 1-2 weeks; in the meantime, supportive cares should be offered.
Primary care practitioners should have access to these resources or be able to advise their patients on how to obtain them, e.g. Written materials, such as the NZHF Myth vs Fact leaflet and The Facts book, should be offered to patients at the first visit with discussion and further questions encouraged at the follow-up and subsequent visits.
The practitioner may also choose to refer patients on to professional counselling, if this is available. The practitioner should be alert to the possibility of further psychological problems manifesting after a diagnosis of genital herpes. It is also helpful to give anticipatory advice over future management options including oral antiviral therapy; recurrent HSV episodes are usually milder than the initial episode and can be treated with either intermittent therapy (treating each episode) or suppressive therapy (treating continuously over a period of months to prevent episodes).
Herpes lesions may become secondarily infected with Staphylococcus aureus and will give the appearance of a folliculitis, similar to mild forms of hydradenitis suppurativa, primary folliculitis, or scabetic nodules. The best method of obtaining confirmation during a recurrence is to take a swab for culture or PCR within 24 hours of symptoms developing.
Written materials, such as the NZHF Myth vs Fact leaflet and The Facts book, should be offered to patients with discussion and further questions encouraged at subsequent visits. The prognosis for successful anti-viral therapy in these infants is far better than that for newborns with more long-standing intrauterine infection.44 Antenatal recurrent disease, where HSV is not shed at delivery, does not have an adverse affect on neonatal outcome and the risk of intrauterine fetal infection from recurrent maternal HSV infection appears to be very low. This may be updated when more information on the effects of aciclovir on the neonate is available. If onset of labour or need for delivery is less than 6 weeks after first clinical episode, deliver by caesarean section.4. About 25 % of the United States populace is infected with genital herpes, with females being more afflicted than men. Upon contact with the blisters, the person who did not experience chicken pox will develop chicken pox instead of shingles.People can be diagnosed with shingles after careful physical assessment. Moreover, the distribution of lesions in women generally extends over areas (labia majora, perineum, perianal area) not protected by condoms. When these occur in the absence of genital lesions, the diagnosis is likely to be missed even if the patient presents for care. However, it lacks the scope of Western blots, having been designed to test for antibodies to HSV glycoprotein G-2 (gG-2) rather than for the entire fingerprint of HSV glycoprotein responses. In contrast, those with HSV-1 infection rarely experience more than one or two episodes a year. However, it is not clear whether a positive PCR assay in patients with a negative culture reflects a true risk of transmission.
All three drugs have been shown to reduce time to cessation of viral shedding and duration of pain. In addition to reduced asymptomatic shedding, it prevents most symptomatic episodes and reduces the severity of those that do occur.
The drug was well-tolerated, with an adverse outcome profile comparable to that of placebo. A patient who has remained partially symptomatic or has experienced prodromes (but not actual recurrences) while taking the drug is likely to become highly symptomatic once antiviral treatment is discontinued. If direct HSV tests are repeatedly negative and the symptoms are recurring, the patient should be advised to have type-specific herpes serology.
False negative and false positive results are common in low prevalence populations and there is no confirmatory serology testing available in New Zealand. Symptoms may sometimes persist for weeks and rarely severe intractable pain may require opiate analgesia. Stevens-Johnson syndrome (erythema multiforme major) is a related, much less common, but much more serious condition.
Confidentiality and sensitivity are paramount; patients need to agree to a third party becoming involved.
Valaciclovir (Valtrex TM) 500mg daily is available for suppressive treatment of recurrent genital herpes subject to a Special Authority restriction. For first or second trimester acquisition, suppressive aciclovir therapy may be used from 36 weeks to reduce recurrences at term and hence the need for caesarean section.
And because few people regard oral-genital contact as risky, the incidence of HSV-1 infection has expanded even faster than that of HSV-2 infection. In both women and men--especially if they practice receptive anal intercourse--viral transverse myelitis or autonomic dysfunction may produce urinary hesitancy and retention, leading to the mislabeling of an entire class of patients as having idiopathic urinary retention. As a result, the test is likely to read as positive an atypical response that includes a gG-2 band but no corroborating evidence--a situation that occurs with a low but significant frequency in the general population, especially among children.
In some studies, men had approximately 20% more recurrences than did women, with the most common sites being the shaft of the penis and the glans.
Since some patients may find one agent more effective than others or complain of headache with one agent but not others, I typically encourage patients to try each for different episodes and then select the one that seems to be most convenient, best tolerated, and most effective. On the other hand, a patient who has remained completely asymptomatic may be able to terminate therapy without ill effects, provided that safer sex practices are maintained. It also should be emphasized that this is a condition in which appearances can be deceiving, and that the source partner may or may not be the one with symptoms. Sero conversion following initial infection is usually 2-6 weeks, but may be longer (months). The ulcers then dry to form crusts and later heal, leaving a transient red macule with minimal scarring (if any). Clinically, this may be indistinguishable from toxic epidermal necrolysis and hospitalisation for supportive cares is indicated. There is also a Herpes Helpline 0508 11 12 13, a telephone service which is free to all New Zealanders. The data from this study was pooled with two other cohorts (from the USA and Sweden) and provided further evidence that during reactivation HSV-1 may be more readily transmissible to the neonate than HSV-2.
The available data on the effect on the neonate is reassuring, although study numbers have been small.5. Although condoms probably offer an advantage, there are no data demonstrating their protection. Bowel dysfunction and impotence are other presentations that are unlikely to suggest herpes to anyone but a virologist. Patients with a primary episode may present with large and painful lesions in these areas and no genital lesions or only a scattering of small vesicles a millimeter or two in diameter on the genitalia.
In women, recurrences tended to affect the labia majora, labia minora, clitoral hood, perineum, or perianal area. Assuming some degree of prior sexual activity in both cases, unless both are tested via Western blot (a good idea, if feasible), there is no way of determining whether the couple is truly discordant or whether one partner is merely asymptomatic.
Also, some do not sero convert and reversal from sero positive to sero negative status may occur if there is minimal antigenic stimulation. Less commonly, lesions can pass through the blister phase quickly and blisters may not be noticed. Clinically, this may be indistinguishable from toxic epidermal necrolysis and hospitalisation for supportive care is indicated. And despite women's higher risk, routine gynecologic examination rarely includes careful inspection of the vulva and perineum, areas where herpes lesions are often found. In patients of both sexes, HSV lesions of the rectal mucosa may cause proctitis associated with anorectal pain, discharge, tenesmus, and constipation. Prior to the appearance of lesions, patients typically experience a localized prodrome such as tingling or itching, although remote symptoms (e.
It is a useful test in some clinical situations, but routine screening of asymptomatic individuals is currently not recommended.
Lesions may also appear extra-genitally, commonly on thighs and buttocks and less commonly on hands, lips, face and breasts. Researches have revealed that shedding might take place in practically 40 % of HSV-2 (normally connected with genital herpes) infected people. But because most HSV-1 infections are transmitted through oral-genital contact, genital herpes can occur in a monogamous relationship with a partner who is seronegative for HSV-2.
Topical anaesthetic jelly such as lignocaine (Xylocaine) gel applied 5 minutes before micturition helps relieve the pain. Asymptomatic viral shedding might last 1 to 5 days, meaning that an individual can be transmittable without presenting any signs at the time. Currently, I'm working as a nurse in a private hospital specifically in the Emergency Room.
More important, most people with either HSV-1 or HSV-2 infection are unaware of it, and a negative history provides no protection at all. As lignocaine is a potential skin sensitizer, patients should be warned to stop application if increasing discomfort occurs after application. The average duration of each duration of viral shedding has been evaluated through lab researches however is simply a quote. So how can you inform for a truth if somebody has genital herpes? If catheterisation is unavoidable, a suprapubic catheter should be used to reduce the risk of ascending infection and is a less painful option. If a test was performed late or provided to the lab late, it might return an incorrect unfavorable outcome.
Western blot test, a blood test, is the most accurate test offered but might return a false negative if the person checked was initially infected within the past 3 months.
It is not simple to understand if an individual has genital herpes or not. One last factor to consider, herpes Simplex 1 or HSV-1 normally triggers oral herpes and fever blisters and herpes simplex-2, genital herpes. It is mainly transmitted during oral sex from a person who's having an oral herpes infection with or without signs. If getting genital herpes is an issue to you, you should consider oral herpes as well as genital herpes when asking a partner. As you can see, it is extremely hard to evaluate if a partner has genital herpes.
