Signs herpes outbreak is coming

However, infants younger than 1 month old and people with weakened immune systems are more likely to have severe illness. Infants may get congenital herpes from a mother with an active herpes infection at the time of birth. HSV meningitis presents similarly to other types of meningitis, with most patients reporting headaches, a stiff neck and fever. Neonatal infection with herpes simplex virus (HSV) occurs in 1 out of every 3200 to 10, 000 live births 1-4, causes serious morbidity and mortality, and leaves many survivors with permanent sequelae. Viruses that can cause meningitis in a newborn include the Coxsackie and the herpes simplex. Some cases of meningitis and encephalitis are caused by bacteria, fungi, and other types of germs. Encephalitis may develop in a person who has meningitis (meh-nin-JY-tis) , an inflammation of the membranes surrounding the brain and spinal cord, called the meninges (meh-NIN-jeez).
Management of herpes simplex encephalitis (HSE) has been considerably improved by the availability of acyclovir therapy and rapid polymerase chain reaction (PCR) based diagnostic assays.
Properly interpreted tests can make cerebrospinal fluid (CSF) a key tool in the diagnosis of a variety of diseases. Data on cerebrospinal fluid (CSF) samples submitted to the Trust Virology Laboratory (Sheffield, UK) from April 2004 through April 2007 were reviewed.
Herpesviruses, both herpes labialis (HSV-1) and genital herpes (HSV-2) , can cause meningitis in children and especially infants. Pediatric aseptic meningitis is an inflammation of the meninges caused mainly by nonbacterial organisms, specific agents, or other disease processes. Mollaret’s meningitis is a recurrent or chronic inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. Meningitis is an important infectious disease to rule out in the pediatric population because it can have serious medical and social complications. HSV-1 is usually acquired orally during childhood and about 6 out of 10 people in the UK carry it. Viral meningitis is contagious, because the viruses that cause the disease are generally easily passed between people.
Meningitis is the inflammation of the meninges (the soft tissue membranes which cover the brain and spinal cord underneath the skull and spinal column). Differences in Laboratory Findings for Cerebrospinal Fluid Specimens Obtained from Patients with Meningitis or Encephalitis Due to Herpes Simplex Virus (HSV) Documented by Detection of HSV DNA. Herpes simplex encephalitis (HSE) is an acute or subacute illness that causes both general and focal signs of cerebral dysfunction. The diagnosis of herpes simplex meningitis was made at the time of the fourth episode by a positive PCR for herpes simplex virus infection in the cerebrospinal fluid.
Other viral infections, such as mumps, herpes simplex viruses (responsible for cold sores) , and influenza can also cause meningitis. Because of the patient’s age and the maternal history of genital HSV infection, the infant was admitted to the hospital, and cefotaxime (Claforan) , ampicillin and acyclovir (Zovirax) were administered. Herpes simplex encephalitis (HSE) is a life-threatening consequence of herpes simplex virus (HSV) infection of the central nervous system (CNS). Mollaret meningitis is a rare form of meningitis that is recurrent, aseptic, mild, and self-limiting.
The commonest organisms causing bacterial meningitis in children over 2 months of age are: Streptococcus pneumoniae.
HighlightsHerpes Simplex VirusesHerpes simplex virus 1 (HSV-1) is the main cause of oral herpes infections that occur on the mouth and lips. Herpes meningitis, an inflammation of the membranes that line the brain and spinal cord, occurs in up to 10 of cases of primary genital HSV-2.
Infants with meningitis frequently present with non-specific symptoms such as fever, irritability, lethargy, poor feeding, vomiting and diarrhoea. There are currently no licensed therapies for enteroviral infection; however, pleconaril, a drug with anti-picornavirus activity, was recently evaluated both in patients with primary immunodeficiency (through a compassionate release programme) and in several clinical trials in enteroviral infections in adults and children, including meningitis in infants 38.
Many of the infections result from asymptomatic cervical shedding of virus after a primary episode of genital HSV in the third trimester.
This virus can be spread by sexual contact or from an infected mother to her baby during childbirth. Listeriosis (lis-teer-e-O-sis) is a bacterial infection that can cause a form of meningitis in infants and other symptoms in children and adults. This may involve herpes simplex virus type 1 (HSV1) , the virus that also causes cold sores. Herpes simplex encephalitis (HSE) is a viral infection of the human central nervous system. The most common causes of acute viral encephalitis are rabies virus, Herpes simplex, poliovirus, measles virus.
After the exclusion of patients with HSV type 2associated meningitis, the study was limited to 98 patients who originated from 2 geographical centers, Paris and Nancy, France. White blood cell differential may be misleading early in the course of meningitis, because more than 10 percent of cases with bacterial infection will have an initial lymphocytic predominance and viral meningitis may initially be dominated by neutrophils. Enterovirus infection was the most common cause of viral meningitis in immunocompetent adults in this study.
When this happens, CSF findings may resemble those of viral meningitis, but antibiotic treatment may need to be continued until there is definitive positive evidence of a viral cause (e.
Bacterial meningitis and viral encephalitis are two life-threatening causes of infection and inflammation within the central nervous system (CNS). Typical features of HSV-2 meningitis are headache, fever, stiff neck, and lymphocytic pleocytosis in the CSF.
A high index of suspicion is required to make the diagnosis of herpes simplex encephalitis (HSE) , and expeditious evaluation is indicated after the diagnosis is considered.
While herpes simples and varicella can cause rash, Mollaret’s patients may or may not have a rash. The recurrent meningeal branch (Arnold’s nerve) to the tentorium cerebelli may account for the meningeal irritation signs and therefore, meningitis must be excluded. HSV-2 is primarily a sexually transmitted infection and is carried by about 1 in 10 of the UK population3. The herpes simplex virus is the second-most-common cause of viral meningitis in adolescents and adults in developed countries, according to the BMJ report. Meningitis is an infection of the membranes (meninges) surrounding the brain and spinal cord. Some of these viruses can also cause encephalitis (infection of the brain substance itself rather than just of the membranes covering the brain).
Both HSV-1 and HSV-2 may produce a more subacute encephalitis, apparent psychiatric syndromes, and benign recurrent meningitis. Both herpes simplex type 1 (herpes labialis) and type 2 (genital herpes) can cause meningitis, typically in infants and children who have been exposed by infected adults. Start empiric acyclovir therapy promptly in patients with suspected HSE pending confirmation of the diagnosis because acyclovir, the drug of choice, is relatively nontoxic and because the prognosis for untreated HSE is poor.
Herpes infection of the CNS, especially with HSV-2, can also cause both monophasic and recurrent aseptic meningitis, as well as myelitis or radiculitis.
On recovery, the patient had no neurological deficits and was discharged from the hospital on a prophylactic dose of acyclovir.
Sterilisation of the CSF can occur within 2 hours after a dose of Ceftriaxone 50 mgkgdose (2g) iv 12H Ceftriaxone for N. Learn about Neonatal Herpes Simplex Virus (HSV) Infection symptoms, diagnosis and treatment in the Merck Manual. Encephalitis is accompanied by viral meningitis whereas aseptic meningitis may occur alone. Neonatal herpes can spread to the brain and central nervous system, causing encephalitis and meningitis and can lead to intellectual disability, cerebral palsy, and death. Neonatal HSV infection, usually with dissemination and a mortality rate similar to that for HSVE, is most often caused by HSV type 2 (HSV-2) transmitted vertically during delivery 5. Less commonly, encephalitis can result from a bacterial infection, such as bacterial meningitis, or it may be a complication of other infectious diseases like syphilis. All newborns suspected to have or who are diagnosed with HSV infection should be treated with parenteral acyclovir. HSVs can cause meningitis or encephalitis (inflammation of the brain itself, which is much more serious). CSF findings in bacterial meningitis may mimic those found in viral meningitis (particularly early on). When an LP is performed, four tubes of CSF, each containing about 1mL of fluid, should be obtained and sent to the laboratory for analysis. The improved pharmacokinetic profiles and simpler dosing regimens of oral valaciclovir (1, 000 mg three times daily for 7 days) or famciclovir (250 mg or 500 mg three times daily) have led to their use instead of aciclovir (800 mg five times daily) as the preferred treatment. Although it primarily involves the brain, it often involves the meninges as well (meningoencephalitis). The inflammation is usually caused by an infection of the fluid surrounding the brain and spinal cord.
Occasionally, children will have viral meningitis associated with mumps or herpes virus infection. Herpes simplex and genital herpes can cause viral meningitis as well as chicken pox, rabies and HIV. PCR of the CSF has a sensitivity of 95 to 100 percent, and a sensitivity of 100 percent for herpes simplex virus type 1, Epstein-Barr virus, and enterovirus. PCR assay of CSF for HSV-1 and HSV-2: Essentially replaced brain biopsy as the criterion standard for diagnosis 7, 8. It can be caused by a variety of viral pathogens including herpes simplex virus (HSV) , which is the most treatable cause of encephalitis. Differentiation of herpes simplex virus (HSV) types 1 and 2 in cerebrospinal fluid of 17 patients with serological1y diagnosed HSV encephalitis and meningitis or acute limbic encephalitis was determined by stringent hybridization of polymerase chain reaction amplified DNAs. Although acyclovir is a safe, effective, and specific anti-Herpes drug, 10, 11 it has not been shown to definitively alter the natural history of the disease, whereas other therapies, including estrogen, steroids, antihistamine, phenylbutazonum, and colchicine have been unsuccessful in the treatment of Mollaret meningitis.
HSV-1 can also cause genital herpes. Herpes simplex virus 2 (HSV-2) is the most common cause of genital herpes, but it can also cause oral herpes.
Adult and pediatric (post-neonatal) HSV encephalitis is caused most commonly by HSV type I.
The prevalence of HSV infection in hospitalized 0- to 28-day-old infants is thought to be about 0. Viral meningitis caused by HSV (HSVM) is a self-limited illness of 25 days’ duration characterized by CSF findings of pleocytosis and an elevated protein level with a normal glucose level.
Herpes simplex virus (HSV) encephalitis is a viral infection in the brain that babies can get from their mothers during delivery.
HSV encephalitis is mainly caused by HSV-1 (which is also the cause of most cold-sores) , whereas meningitis is more often caused by HSV-2 (the cause of most genital herpes). The CSF analysis shows elevated opening pressure, elevated protein, low glucose (hypoglycorrhachia) , cloudy fluid and a positive Gram stain. There are two main types of herpes simplex virus (HSV) ; type 1, which is mainly associated with facial infections and type 2, which is mainly genital, although there is considerable overlap. Meningitis can be caused by viruses, like enteroviruses, arboviruses and herpes simplex viruses.
Most new cases of genital herpes infection do not cause symptoms, and many people infected with HSV-2 are unaware that they have genital herpes.
Polymerase chain reaction (PCR) of the cerebrospinal fluid (CSF) is the diagnostic method of choice for HSE, but negative results need to be interpreted in the context of the patient’s clinical presentation and the timing of the CSF sampling. CSF findings suggestive of bacterial meningitis include the following: Mollaret meningitis is a rare form of meningitis that is recurrent, aseptic, mild, and self-limiting.
Trends in HSV Types and Genital HerpesGenital herpes can be caused by either HSV-2 or HSV-1.
If active HSV infection is present at the time of delivery, cesarean section should be performed.
If doctors think that a newborn has herpes encephalitis resulting from infection with HSV2 while passing through the birth canal, they may check samples of the baby’s blood and spinal fluid. Focal neurological signs or seizures are rare, except in neonates who are most at risk of developing meningoencephalitis and severe systemic complications such as myocarditis or necrotizing enterocolitis, which are associated with substantial mortality. Herpes simplex viruses can involve the brain and its lining to cause encephalitis and meningitis. Symptoms include fever, headache, and altered mental status, often accompanied by seizures or focal neurologic deficits. Herpes simplex virus (HSV) remains an important cause of meningitis and encephalitis in adults, and polymerase chain reaction (PCR) -based tests are the gold standard for diagnosis.
Detection of Herpes DNA in the CSF will allow the clinician to use abortive and preventive antiviral therapy.
In babies (and with some viruses in adults also) there is often severe involvement of other organs. Children aged one year or less and adults aged 55 years and over are more vulnerable to life threatening complications. Aseptic meningitis occurs in 36 of women with primary HSV-2 genital infection and 13 of men5; it results in hospitalization for 6.


In the newborn, herpes viruses cause severe infections along with brain, lung, and liver disease as well as skin and eye sores. Viruses that can cause encephalitis include enteroviruses such as poliovirus and echovirus, herpes simplex virus, varicella-zoster virus, Epstein-Barr virus, cytomegalovirus, adenovirus, rubella, measles, Murray Valley encephalitis (MVE) virus, Kunjin virus and Japanese encephalitis virus. Characteristics include usually normal opening pressure, slightly increased protein and normal glucose (glucose is below normal for bacterial meningitis). There is a broad range in relative concentrations of HSV DNA in the CSF in cases of meningitis and encephalitis. Culture of HSV from the cerebrospinal fluid (CSF) of adults with HSE has a sensitivity of less than 10 percent. The portal of entry in many is presumed to be through the nasal mucosa or by direct extension from the adjacent trigeminal ganglion (in whose cells the virus is dormant).
5 per 100, 000 individuals most commonly in children, the elderly, and people with weakened immune systems (e.
Group B Strep Group B strep are bacteria called Streptococcus agalactiae that may sometimes cause infections both in a pregnant woman and her newborn.
In patients with enterovirus-associated CEMA, many would advocate a high-dose immunoglobulin therapy, particularly for complications outside the CNS. Increasing the dose of acyclovir for the treatment of drug-resistant HSV infections is rarely successful because mutations in the thymidine kinase gene are responsible for drug resistance.
In recent years, HSV-1 has become a significant cause in developed countries, including the United States. Meningitis: infection of the meninges (the membranes that surround the brain and spinal cord). Herpes simplex (HSV) encephalitis is the most common cause of fatal sporadic fulminant necrotizing viral encephalitis and has characteristic imaging findings. In contrast to aseptic viral meningitis, neuropsychiatric symptoms often predominate in encephalitis, for example, anomia, hallucinations, psychosis, personality changes, and agitation. Infection of the nervous system can involve the meninges (meningitis) or the brain substance itself (encephalitis) , or both (meningoencephalitis). Differences in laboratory findings for cerebrospinal fluid specimens obtained from patients with meningitis or encephalitis due to herpes simplex virus (HSV) documented by detection of HSV DNA.
In: Current Pediatric Therapy, 18th, Burg FD, Ingelfinger JR, Polin RA, Gershon AA (Eds) , Saunders, Philadelphia 2006.
With high-dose acyclovir therapy, the mortality rate for disseminated neonatal HSV disease is 29 (112). Herpes simplex encephalitis (HSE) tends to be most severe when it affects children and older people. The cerebrospinal fluid profile in acute viral encephalitis is indistinguishable from aseptic meningitis. This definition means encephalitis is different from meningitis, which is defined as inflammation of the layers of tissue, or membranes, covering the brain. 6 cases per 100, 000 persons, and the most common etiologies are enterovirus, HSV, and varicella-zoster virus infections. It has no apparent regular structure but along with the envelope components, the tegument proteins of herpes simplex virus type 1 (HSV-1) can assemble to give non-infectious particles termed light particles that lack nucleocapsids. Viral infection of the arachnoid membrane and CSF causes headache, stiff neck and mononuclear CSF pleocytosis with normal protein and glucose. The role of antiviral therapy in the management of aseptic meningitis associated with genital herpes has not been systematically evaluated, although use of systemic antiviral therapy in the treatment of primary genital herpes decreases the subsequent development of aseptic meningitis (47).
In order to better understand meningitis one must first have knowledge about the structures surrounding the brain. Viral meningitis is inflammation of the leptomeninges as a manifestation of central nervous system (CNS) infection. The viral control was 1105 plaque-forming units of either HSV-1 (clinical isolate) or HSV-2 (strain G, American Type Culture Collection) , which was prepared in a total lysate volume of 100 l.
The risk of infection is highest during outbreak periods when there are visible sores and lesions. HSV-2 genital infection may precede meningitis; sexual contact with actively infected individuals is one of the known risk factors. Herpes simplex (HSV) encephalitis is the most common cause of fatal sporadic fulminantnecrotizing viral encephalitis and has characteristic imaging findings. HSV encephalitis is predominantly caused by HSV-1, whereas meningitis is more often caused by HSV-2, although is not always associated with episodes of genital herpes. Tests that are used in the evaluation of individuals suspected of having encephalitis or meningitis include evaluation of the blood for signs of infection and possible presence of bacteria, brain scanning (such as CT scanning or MRI scan) , and cerebrospinal fluid analysis. Extralimbic involvement is more common in children than in adult, seen most commonly in the parietal lobe, with sparing of basal ganglia. Symptoms and signs of encephalitis can include fever, headache, lethargy, irritability, confusion, focal deficit, aphasia and seizures, and they reflect virus replication with accompanying inflammation in the medial temporal lobe and orbital surface of the frontal lobe. Of greatest concern is the risk of primary infection acquired at birth which could lead to herpetic meningitis. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms, and less commonly by certain drugs.
SymptomsWhen genital herpes symptoms do appear, they are usually worse during the first outbreak than during recurring attacks. Patients with these infectious diseases may present to the Emergency Department with similar signs and symptoms, and the diagnosis can be challenging to discern in the early stages of illness. The incidence of brain damage varies with the severity of the meningitis and the organism, and tends to be high in neonatal meningitis.
MENINGITIS AND ENCEPHALITIS are two of the most common central nervous system (CNS) inflammations you’ll encounter when caring for hospitalized patients.
Herpes, Pregnancy, and Newborn InfantsHerpes can pose serious risks for a pregnant woman and her baby. The symptoms in infants may be a bit more difficult to identify, but it is important to rule out bacterial meningitis, which is a much more dangerous condition. Because meningitis is contagious, maintain isolation precautions as appropriate, following the new CDC guidelines. The risk is greatest for mothers with a first-time infection, because the virus can be transmitted to the infant during childbirth. Bacterial meningitis in the older child is usually characterized by hedache, andor a change in the level of mental status.
Meningitis and encephalitis are inflammatory diseases of the membranes that surround the brain and spinal cord and are caused by bacterial or viral infections. Guidelines from the American Academy of Pediatrics recommend using specific diagnostic tests for women in labor to determine the risk of transmission.
In infants, symptoms of meningitis may include irritability or fatigue, lack of appetite, and fever. Babies born to mothers infected with genital herpes are often treated with the antiviral drug acyclovir, which can help suppress the virus.
In infants, increased intracranial pressure and continued fever may result from a subdural effusion.
Neonatal HSV infection, defined as infection in a newborn within 28 days after birth, is a devastating consequence of untreated or unmonitored genital herpes. Herpes viruses include human herpes virus 8 (the cause of Kaposi sarcoma) and varicella-zoster virus (also known as herpes zoster, the virus responsible for shingles and chickenpox). The word "herpes" comes from the Greek word "herpein," meaning "to creep." This refers to the unique characteristic pattern of all herpes viruses to creep along local nerve pathways to the nerve clusters at the end, where they remain in an inactive (dormant) state for variable periods of time. The usual cause of oral herpes (herpes labialis), which are commonly called cold sores or fever blisters.
HSV-1 can also cause genital herpes, which is a sexually transmitted disease (STD). Herpes simplex virus 2 (HSV-2). Until recently, the general rule was to assume that HSV-1 caused oral herpes and HSV-2 caused genital herpes.
It is now clear, however, that either type of herpes virus can be found in the genital or oral areas (or other sites). In fact, HSV-1 is now responsible for more than half of all new cases of genital herpes in developed countries. The Disease ProcessHerpes is transmitted through close skin-to-skin contact. To infect people, the herpes simplex viruses (both HSV-1 and HSV-2) must get into the body through tiny injuries in the skin or through a mucous membrane, such as inside the mouth or on the genital or anal areas. The risk for infection is highest with direct contact of blisters or sores during an outbreak. But the infection can also develop from contact with an infected partner who does not have visible sores or other symptoms. Once the virus has contact with the mucous membranes or skin wounds, it enters the nuclei of skin tissue cells and begins to replicate.
The virus is then transported from the nerve endings of the skin to clusters of nerve cells (ganglia) where it remains inactive (latent) for some period of time. However, at some point, the virus wakes up and travels along nerve pathways to the surface the skin where it begins to multiply again. During this time, the virus can infect other people if it is passed along in body fluids or secretions. Viral shedding may be accompanied by noticeable symptoms (outbreak) but it can also occur without causing symptoms (asymptomatic shedding). In either case, a person is infectious during periods of viral shedding. Symptoms may appear as multiple small red bumps or patches that develop blisters. Certain triggers can wake up the virus from its dormant state and cause it to become active again. In general, recurrent episodes of herpes cause less severe symptoms than the primary outbreak.
HSV-1 is the most prevalent form of herpes simplex virus, and infection is most likely to occur during preschool years. In addition, because HSV-1 can be passed in saliva, people should also avoid sharing toothbrushes or eating utensils. Transmission of Genital Herpes Genital herpes is transmitted through sexual activity.
People can get HSV-2 through genital contact or HSV-1 through mouth-to-genital contact with an infected partner. People with active symptoms of genital herpes are at very high risk for transmitting the infection.
Unfortunately, most cases of genital herpes infections occur when the virus is shedding but producing no symptoms. Most people either have no symptoms or do not recognize them when they appear. In the past, genital herpes was mostly caused by HSV-2, but HSV-1 genital infection is increasing.
There is also evidence that children today are less likely to get cold sores and become exposed to HSV-1 during childhood. Centers for Disease Control and Prevention (CDC), about 1 in 6 Americans ages 14 to 49 years have genital herpes. While HSV-2 remains the main cause of genital herpes, HSV-1 has significantly increased as a cause, most likely because of oral-genital sex. African-American women are at particularly high risk. People with compromised immune systems, such as those who have HIV, are at very high risk for genital herpes. Drugs that suppress the immune system, and organ transplantation, can also weaken the immune system and increase the risk for contracting genital herpes.
It is almost impossible to defend against the transmission of oral herpes, because it can be transmitted by very casual contact, including kissing. Still, you can help reduce the risk of transmitting oral herpes by not sharing objects that touch the mouth, such as eating and drinking utensils, toothbrushes, and towels.
It is best to refrain from any type of sex (vaginal, anal, or oral) during periods of active outbreak. However, herpes can also be transmitted when symptoms are not present (asymptomatic shedding). Although condoms may not provide 100% protection, they are proven to significantly reduce the risk of sexual disease transmission, including herpes. Natural condoms made from animal skin do NOT protect against HSV infection because herpes viruses can pass through them. Use a water-based lubricant.
Lubricants can help prevent friction during sex, which can irritate the skin and increase the risk for outbreaks. Only water-based lubricants (K-Y Jelly, Astroglide, AquaLube, and glycerin) should be used. However, it is best not to use condoms pre-lubricated with spermicides. Do not use spermicides for protection against herpes. Nonoxynol-9 can cause irritation around the genital areas, which makes it easier for herpes and other STDs to be transmitted. Use a dental dam or condom for oral sex.
If you have any symptoms of oral herpes, it is best not to perform oral sex on a partner until any visible sores or blisters have healed. Limit the number of sexual partners. The more sexual partners you have, the greater your chances of becoming infected or infecting others. It is very unlikely to transmit or contract genital herpes from a toilet seat or bath towel. Studies suggest that male circumcision may help reduce the risk of HSV-2, as well as human papillomavirus (HPV) and HIV infections. However, herpes can cause significant and widespread complications in people who don't have a fully functioning immune system.
The CDC recommends that all people diagnosed with herpes simplex virus 2 (HSV-2) get tested for HIV. Most people with HIV are co-infected with HSV-2 and are particularly vulnerable to its complications. HSV-2 infection increases HIV levels in the genital tract, which makes it easier for the HIV virus to be spread to sexual partners. Herpes and PregnancyPregnant women who have genital herpes due to either HSV-2 or HSV-1 have an increased risk for miscarriage, premature labor, inhibited fetal growth, or transmission of the herpes infection to the infant in the uterus or at the time of delivery.


Herpes in newborn babies (herpes neonatalis) can be a very serious condition. Fortunately, neonatal herpes is rare. Although about 25 to 30% of pregnant women have genital herpes, less than 0.1% of babies are born with neonatal herpes. The baby is at greatest risk during a vaginal delivery, especially if the mother has an asymptomatic infection that was first introduced late in the pregnancy.
The risk for transmission also increases if infants with infected mothers are born prematurely, there is invasive monitoring, or instruments are used during vaginal delivery. Transmission can occur if the amniotic membrane of an infected woman ruptures prematurely, or as the infant passes through an infected birth canal.
This risk is increased if the woman is having or has recently had an active herpes outbreak in the genital area. Very rarely, the virus is transmitted across the placenta, a form of the infection known as congenital herpes. Aggressive treatment with antiviral medication is required. Most infected pregnant women do not have a history of symptoms, so herpes infection is often not suspected or detected at the time of delivery. Fortunately, if a woman does have genital lesions, rapid diagnostic blood tests can quickly determine her chances of transmitting the virus to her baby during delivery. Some women with new or recurrent herpes may also be prescribed antiviral medication during pregnancy.
A woman with herpes can usually safely breastfeed her baby, as long as she does not have a lesion on her breast or nipple. Neonatal herpes can spread to the brain and central nervous system, causing encephalitis and meningitis. Herpes can also spread to internal organs, such as the liver and lungs. Infants infected with herpes are treated with acyclovir, an antiviral drug.
They usually receive several weeks of intravenous acyclovir treatment, often followed by several months of oral acyclovir. It is important to treat babies quickly, before the infection spreads to the brain and other organs.
Fortunately, rapid diagnostic tests and treatment with acyclovir have significantly improved survival rates and reduced complication rates.
Nearly all who recover have some impairment, ranging from very mild neurological changes to paralysis.
Like encephalitis, meningitis symptoms include headache, fever, stiff neck, vomiting, and sensitivity to light. Ocular herpes is usually a simple infection that clears up in a few days, but in its more serious forms, and in severe cases, it can cause blindness.
It only affects the upper layer (epithelium) of the cornea and heals with scarring. Stromal Keratitis.
Iridocyclitis is another serious complication of ocular herpes, in which the iris and the area around it become inflamed.
Herpes Skin ComplicationsEczema Herpeticum A rare form of herpes infection called eczema herpeticum, also known as Kaposi varicelliform eruption, can affect people with skin disorders and those with a weakened immune system. Untreated, this condition can be extremely serious and possibly fatal. Gingivostomatiti Oral herpes can cause multiple painful ulcers on the gums and mucus membranes of the mouth, a condition called gingivostomatitis.
In children, this is often caused by thumb sucking or finger sucking while they have a cold sore. It can also occur in adult health care workers, such as dentists, because of increased exposure to the herpes virus. The use of latex or polyurethane gloves prevents herpes whitlow in health care workers. SymptomsHerpes symptoms vary depending on whether the outbreak is initial or recurrent.
The primary outbreak is usually worse than recurrent outbreaks, with more severe and prolonged symptoms.
In fact, studies indicate that 10 to 25% of people infected with HSV-2 are unaware that they have genital herpes. The first signs are a tingling sensation in the affected areas (genitalia, buttocks, and thighs) and groups of small red bumps that develop into blisters. The sores may sometimes itch, but itching decreases as they heal. About 40% of men and 70% of women develop other symptoms during initial outbreaks of genital herpes, such as flu-like discomfort, headache, muscle aches, and fever. Some women may have difficulty urinating and may, occasionally, require a urinary catheter.
Women may also experience vaginal discharge. Recurrent Genital Herpes Outbreak In general, recurrences are much milder than the initial outbreak. The virus sheds for a much shorter period of time (about 3 days) compared to an initial outbreak of 3 weeks. Women may have only minor itching, and the symptoms may be even milder in men. On average, people have about four recurrences during the first year, although this varies widely.
There are some differences in frequency of recurrence depending on whether HSV-2 or HSV-1 caused genital herpes. HSV-2 genital infection is more likely to cause recurrences than HSV-1. Symptoms of Oral HerpesOral herpes (herpes labialis) is most often caused by HSV-1, but it can also be caused by HSV-2. It usually affects the lips and, in some primary attacks, the mucus membranes in the mouth. A herpes infection may occur on the cheeks or in the nose, but facial herpes is very uncommon. Primary Oral Herpes Infection If the primary (initial) oral infection causes symptoms, they can be very painful, particularly in children.
The sores last 10 to 14 days and can be very uncomfortable. Blisters that may be preceded or accompanied by sore throat, fever, swollen glands, and painful swallowing.
Recurrent Oral Herpes Infection A recurrent oral herpes infection is much milder than the primary outbreak.
It usually manifests as a single sore, commonly called a cold sore or fever blister (because it may arise during a bout of cold or flu). The sore usually shows up on the outer edge of the lips and rarely affects the gums or throat.
Recurrences of genital herpes are more likely with HSV-2 infection than with HSV-1 infection. The outbreak of infection is often preceded by a prodrome, an early group of symptoms that may include itchy skin, pain, or an abnormal tingling sensation at the site of infection. Recurrent outbreaks feature most of the same symptoms at the same sites as the primary attack, but they tend to be milder and briefer.
Occasionally, the symptoms may not resemble those of the primary episode, but appear as fissures and scrapes in the skin or as general inflammation around the affected area. They include sunlight, wind, fever, physical injury, surgery, menstruation, suppression of the immune system, and emotional stress.
Oral herpes can be triggered within about 3 days of intense dental work, particularly root canal or tooth extraction. Timing of Recurrences Recurrent outbreaks may occur at intervals of days, weeks, or years.
For most people, outbreaks recur with more frequency during the first year after an initial attack. The good news is that in most healthy people, recurring infections tend to become progressively less frequent, and less severe, over time. However, other conditions can resemble herpes, and doctors cannot base a herpes diagnosis on visual inspection alone. These tests include: Virologic tests (viral culture of the lesion) Serologic tests (blood tests that detect antibodies) The CDC recommends that both virologic and serologic tests be used for diagnosing genital herpes.
People diagnosed with genital herpes should also be tested for other sexually transmitted diseases.
At this time, experts do not recommend screening for HSV-1 or HSV-2 in the general population. Genital herpes can be caused by either HSV-1 or HSV-2.
It is important to determine which virus is involved, as the type of herpes infection influences prognosis and treatment recommendations. Recurrences of genital herpes, and viral shedding without overt symptoms, are much less frequent with HSV-1 infection than with HSV-2. False-negative (testing negative when herpes infection is actually present) or false-positive (testing positive when herpes infection is not actually present) results can occur.
Your health care provider may recommend that you have a test repeated. Virologic TestsViral culture tests are made by taking a fluid sample, or culture, from the lesions as early as possible, ideally within the first 48 hours of the outbreak. PCR tests are much faster and more accurate than viral cultures, and the CDC recommends PCR for detecting herpes in spinal fluid when diagnosing herpes encephalitis.
PCR can make many copies of the virus' DNA, so that even small amounts of DNA in the sample can be detected.
However, many labs now use PCR for herpes testing because it is highly accurate. An older type of virologic testing, the Tzanck smear test, uses scrapings from herpes lesions. The scrapings are stained and examined under a microscope for the presence of giant cells with many nuclei or distinctive particles that carry the virus (called inclusion bodies). The Tzanck test is not reliable for providing a conclusive diagnosis of herpes infection and is not recommended by the CDC. Serologic TestsSerologic (blood) tests can identify antibodies that are specific for either HSV-1 or HSV-2. When the herpes virus infects you, your body's immune system produces specific antibodies to fight off the infection. If a blood test detects antibodies to herpes, it is evidence that you have been infected with the virus, even if the virus is in a non-active (dormant) state. The presence of antibodies to herpes also indicates that you are a carrier of the virus and might transmit it to others. Serologic tests can be especially useful for people who do not have active symptoms, but who have other risk factors for herpes (such as other STDs, multiple sex partners, or a monogamous partner who has genital herpes).
Although glycoprotein (gG) type-specific tests have been available for many years, many of the older nontype-specific tests that cannot distinguish HSV-1 from HSV-2 are still on the market. Canker sores frequently crop up singly or in groups on the inside of the mouth, or on or underneath the tongue. The drugs are used initially to treat a first attack of herpes, and then afterward to either treat recurrent outbreaks (episodic therapy) or reduce frequency of recurrences (suppressive therapy). Drugs can, however, reduce the severity of symptoms, improve healing times, and prevent recurrences. If people experience very severe disease or complications, they need to be hospitalized and receive an antiviral drug intravenously. Your health care provider will prescribe one of the three antiviral medications, which you will take for 7 to 10 days. You should begin the medication as soon as you notice any signs or symptoms of herpes, preferably during the prodrome stage that precedes the outbreak of lesions. If taken during prodrome, episodic therapy may help prevent an outbreak from occurring or reduce its severity. Valacyclovir is taken once a day. Suppressive treatment can reduce the frequency of outbreak recurrences by 70 to 80%.
It is generally recommended for people who have frequent recurrences (6 or more outbreaks per year). Because herpes recurrences often diminish over time, you should discuss annually with your health care provider whether you should stay with drug therapy or discontinue it. While taking any suppressive therapy for genital herpes, it is still important to regularly use latex condoms and to avoid any sexual activity during recurrences. A new form of acyclovir (Sitavig) is administered orally as an adhesive tablet; it is applied to the gum region of the mouth, where it dissolves during the course of the day. In addition, acyclovir is available in topical form, as is the related drug penciclovir (Denavir). Topical TreatmentsThese ointments or creams can help shorten healing time and duration of symptoms. However, none are truly effective at eliminating outbreaks. Penciclovir (Denavir) heals HSV-1 sores on average about half a day faster than without treatment, stops viral shedding, and reduces the duration of pain.
Ideally, you should apply the cream within the first hour of symptoms, although the medication can still help if applied later. Apply the cream 5 times a day, beginning at the first sign of tingling or pain. Over-the-counter topical ointments may provide modest relief. They include Anbesol gel, Blistex lip ointment, Campho-phenique, Herpecin-L, Viractin, and Zilactin. Some contain a topical anesthetic such as benzocaine, tetracaine, or phenol. Lip balm that contains sunblock, or sunscreen applied around the lips may help prevent sun-triggered outbreaks.
Herbs and SupplementsGenerally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful.
There have been several reported cases of serious and even lethal side effects from herbal products.
Always check with your provider before using any herbal remedies or dietary supplements. Many herbal and dietary supplement products claim to help fight herpes infection by boosting the immune system.
There has been little research on these products, and little evidence to show that they really work. Epidemiology, clinical presentation, and antibody response to primary infection with herpes simplex virus type 1 and type 2 in young women.
