Signs herpes outbreak is coming

This is a viral infection of the lips and mouth which is caused by the herpes simplex virus a€“ termed HSV.
Herpes doesna€™t always develop symptoms a€“ it does not always cause any outward, visible signs. Kissing or touching and any sexual contact with the area that is infected spreads oral herpes. Many individuals have symptoms of itching, burning, and tingling proceeding the outbreak of blisters or sores. The most concentrated pain from these sores occurs at the onset and can make drinking or eating hard.
If a child with cold sores is less than 6 weeks old, the babya€™s physician needs to be notified if oral blisters or sores appear.
Individuals with weakened immunity systems should also notify their primary care physician if sores or blisters appear.
A physician will make a tentative diagnosis on data provided by the patient and on the physician exam. Topical anesthetic such as lidocaine (xylocaine, Nervocaine, Dilocaine, Zilactin-L) can be approved for pain relieve of oral blisters and lesions.
Oral or IV drugs exist for HSV but only for individuals with weakened immune systems, infants younger than 6 weeks or those with severe disease.
Topical Denavir (penciclovir) creams can shorten attacks of recurrent HSV-if it is applied early, normally before lesions develop.
These medications may stop viral reproduction in the skin but do not eradicate HSV from the body or stop later outbreaks.

These guidelines aim to provide comprehensive information about sexually transmitted herpes simplex virus (HSV) infection and its laboratory diagnosis in eastern European countries. During the past 20 years, genital herpes has emerged as one of the most prevalent sexually transmitted infections (STIs).
The clinical differentiation of genital HSV infection from other infectious and non-infectious aetiologies of genital ulceration is difficult and laboratory confirmation of the infection should always be sought [5,9]. The guidelines presented here represent the first attempt to introduce an evidence-based approach to the laboratory diagnosis of genital herpes infections in eastern Europe.
Laboratory confirmation of the clinical diagnosis is necessary for estimating the potential infectivity during episodes of lesions, identifying persons at risk of transmitting infection subclinically, selecting women at future risk of transmitting the infection to the neonate and confirming the clinical diagnosis in those for whom antiviral therapy for HIV infection should be prescribed [8]. Methods used for the diagnosis of HSV could be divided into direct detection of virus in material from lesions and serological diagnosis. The recommended sampling sites and type of sample and methods to be used for the diagnosis of genital herpes infection are presented in Table 4. The recommendations for sample transportation for testing using microscopy, culture and NAATs are presented in Table 5. The recommended sites and methods to be used for the diagnosis of genital herpes infection are presented in Table 6. Microscopic examination of lesion materials using Romanovsky staining is used by a number of laboratories in Eastern Europe [17].
Viral antigen from swab specimens can be detected using either direct immunofluorescence (DIF) or enzyme immunoassay (EIA). DIF could be classified as a rapid diagnostic test allowing type differentiation of genital herpes viruses [19,20]. The sensitivity of commercially available EIAs, when compared with that of viral isolation, is greater than or equal to 95% and with specificities ranging from 62% to 100% for symptomatic patients [22-27].
Virus isolation in cell culture has been the cornerstone of HSV diagnosis over the past two decades in laboratories of western Europe [28,29] and the United States [30]. Virus isolation in tissue culture roller tubes is slow and labour intensive, but has the advantage of demonstrating active infection within a clinical lesion and also allows virus typing and antiviral sensitivity testing [32]. Typing of HSV using cell culture can be performed directly on infected cell cultures using fluorescein isothiocyanate (FITC)- or immunoperoxidase-labelled type-specific monoclonal antibodies by DIF or by testing the cell supernatant by nucleic acid amplification tests (NAATs), with specifically designed primers. HSV detection using polymerase chain reaction (PCR) has been shown to be the test of choice in patients with genital herpes ulcers. As in western Europe and the United States, there are no comprehensively validated and approved commercial NAATs available for detection of HSV in many eastern European countries. In each DNA extraction and subsequent analysis, an internal positive control – allowing detection of amplification-inhibited samples and controlling the quality of sample preparation – and a negative control are necessary. Certified and registered reference panels comprising coded control specimens should ideally be used for intra- and inter-laboratory quality control. Serological tests detect antibodies to HSV in blood, which are indicative of ongoing latent infection.
General criteria for the validation of diagnostic tests have been published by the TDR diagnostics evaluation expert panel (TDR is a Special Programme for Research and Training in Tropical Diseases, sponsored by the United Nations Children's Fund (UNICEF), the United Nations Development Programme (UNDP), the World Bank and WHO [44].
Older, classical tests can display cross-reactivity between HSV-1 and HSV-2 and even with varicella-zoster virus.
Where viral culture facilities exist, they should be maintained in order to detect the causative virus directly from skin and mucous membrane lesions.

Disclaimer: The opinions expressed by authors contributing to Eurosurveillance do not necessarily reflect the opinions of the European Centre for Disease Prevention and Control (ECDC) or the editorial team or the institutions with which the authors are affiliated. They are primarily intended for professionals testing specimens from patients at a sexual healthcare clinic but may also be helpful for community-based screening programmes. However, data on morbidity due to genital herpes infections in eastern European countries is scarce and their reliability doubtful owing to the lack of validation studies for the diagnostic tests used.


In general, infections caused by HSV-1 manifest above the neck and are acquired as a result of close contact with infected persons, usually in childhood. The recurrences arise with different frequency: from once every few years to several times per month. Neonatal herpes (including neonatal encephalitis) and increased risk for acquiring and shedding human immunodeficiency virus (HIV) are the most serious consequences of genital herpes infection [8,9]. Accordingly, exclusive reliance on clinical diagnosis could lead both to false positive and false negative diagnosis of the condition [6,9].
It is recognised that national adjustments to these guidelines may be needed in some eastern European countries to meet local laws and health strategies and according to the availability of kits and reagents. Both virological detection and type-specific serological tests for HSV should be available in clinical settings that provide care for patients with STIs or those at risk for STIs. This method, however, as well as cytological examination using Tzanckand Papanicolaou smears, have been found to have low sensitivity and specificity, and therefore should not be relied upon for diagnosis [5,9,18]. Commercial diagnostic tests produced in eastern European countries for the detection of herpes-specific virus antigen have not been validated against any international standard test; therefore the data presented below reflect characteristics of tests produced in western countries. It can be valuable when testing high-prevalence populations [21], but when testing asymptomatic patients, the sensitivity may drop to less than 50% when compared with culture [19,21]. The sensitivity of antigen capture EIAs may be higher than that of virus culture for typical presentations, but lower for cervical and urethral swabs [22-24,27].
Although HSV can be isolated from over 90% of vesicular or pustular lesions, the isolation rate from ulcerative lesions is only 70% and falls to 27% at the crusting stage [4]. More rapid culture of HSV can be achieved by using shell vials [33] or multiwell plates [34] and centrifuging the specimen onto cell monolayers on coverslips. The detection rates of the PCR assays were shown to be 11–71% superior to virus culture [30,31,37-39]. However, some NAATs for HSV detection have been developed and are available in eastern Europe, but have not been validated against their internationally acknowledged analogues. Both type- and non-type-specific antibodies to HSV develop during the first several weeks after infection and persist indefinitely. During the past 20 years, a number of type-specific tests have been developed, the sensitivity and specificity of which have been evaluated to be approximately 97% and 98%, respectively [46].

Neither ECDC nor any person acting on behalf of ECDC is responsible for the use that might be made of the information in this journal. The World Health Organization (WHO) has estimated a prevalence of herpes simplex virus type 2 (HSV-2) infection of 29 million cases in men and 12.3 million cases in women in eastern Europe and central Asia in 2003 [1].
In contrast, the lesions of infections caused by HSV-2 are usually located below the waist and are usually acquired as a result of sexual contact with infected persons later in life.
The main clinical symptoms, manifestations and complications of genital herpes infections are summarized in Table 2.


HSV is the most common cause of sexually acquired genital ulceration, however, the role of causative agents of other STIs, such as Treponema pallidum and Haemophilus ducreyi should not be forgotten. They are a consensus document of the Eastern European Sexual and Reproductive Health (EE SRH) Network [11,12] and comprise one element of a series of guidelines aimed at optimising, standardising and providing guidance on quality assurance of laboratory testing for reproductive tract infections [13-16]. The disadvantages of DIF are that it is time consuming, labour intensive and, compared to NAATs, has a suboptimal sensitivity. Delayed transport of samples to the laboratory and lack of refrigeration during transportation substantially affect the outcome of the testing [31]. Commonly used cells include primary human fibroblasts and cell lines such as MRC-5, Vero cells, baby hamster kidney and rabbit kidney cells [35,36]. Furthermore, compared with traditional PCR, real-time PCR allows detection and typing of HSV in a single reaction tube, is faster (takes approximately two hours to perform), allows simplified conditions of performance and lowers the risk of cross-contamination [37]. These act as indicators of sensitivity, specificity and reproducibility, which are independent of the test systems used. However, directly after infection there is a ‘window’ in which testing for antibodies will give a negative result.
However, the minimum requirements for the validation of a new or modified test have also been published [45].
Although the benefits of the serological assays (such as type-specific EISAs) include the possibility of automation and therefore simultaneous processing of a large number of samples at relatively low cost, they have a number of disadvantages that considerably limit their use in the diagnosis of genital herpes.
If NAATs are not available, antigen detection, namely DIF or EIA, could be employed, if high performance of those tests can be assured.

The international classification of diseases caused by herpes virus (anogenital) [2] is presented in Table 1. Unfortunately, the differentiation of HSV-1 from HSV-2 based on anatomical site of infection is not absolute, since genital herpes may frequently be caused by HSV-1 as a result of oro-genital sexual practices and vice versa.
This episode resolves spontaneously, but recurrences may occur as a result of reactivation of the infection that has become latent but persists in the cervical ganglia. Both oral and genital herpes are manifested by acute recurrences followed by varying periods of latency, when the virus remains in a non-multiplying episomal form in the nuclei of the neurons in the ganglia. They are primarily intended for professionals testing specimens from patients at sexual healthcare clinics but may also be helpful for community-based screening programmes. The characteristic cytopathic effect of HSV in tissue culture generally appears within 24–72 hours, but may take up to five days. Use of NAATs for diagnosis of HSV also allows less strict sample transportation conditions, compared with those required for diagnosis by culture.
Serodiagnosis is useful for documenting newly acquired infections and for diagnosis in persons who present without lesions or with atypical lesions. Similarly, if an individual has not been exposed to HSV-1 in childhood, he or she may develop severe genital lesions following sexual exposure to HSV-2 later in life. Classically, each episode or recurrence is characterised by a patch of redness at the site of the recurrence, followed by a localised papular then vesicular rash. Testing for HSV type-specific antibodies can also be used to diagnose HSV-2 infection in asymptomatic individuals [31,40], and other persons with undiagnosed HSV-2 infection.
Unfortunately, serological tests alone cannot inform the aetiology of a presenting genital lesion with any degree of certainty.
Type-specific serology should be used for detecting asymptomatic individuals, testing pregnant women at risk of acquiring HSV infection close to delivery, men who have sex with men, and people who are HIV positive. Except where otherwise stated, all manuscripts published after 1 January 2016 will be published under the Creative Commons Attribution (CC BY) licence. However, because HSV-2 is almost always associated with genital disease, whereas HSV-1 is associated with both oro-pharyngeal and genital disease, there is often considerable stigma associated with HSV-2 infection.
As with HSV-1 infections, primary HSV-2 infections resolve spontaneously but recurrences are likely to occur as a result of reactivation of latent infection that has been established in the sacral ganglia. The vesicles contain a clear fluid that contains many thousands of infectious viral particles.
Non-infectious causes of genital ulceration, such as inflammatory bowel disease (Crohn disease), mucosal ulcerations associated with Behcet syndrome or fixed drug eruption, may also be confused with genital herpes [9]. You are free to share and adapt the material, but you must give appropriate credit, provide a link to the licence, and indicate if changes were made. Acquisition of HSV-1 usually results in lesions of the oro-pharynx and around the mouth and on the lips and chin. These vesicles burst, forming shallow ulcers or erosions that eventually crust and heal spontaneously without leaving scars. The types of persons who are recommended to be tested for genital herpes infections are listed in Table 3. Up to 50% of first-episode cases of genital herpes are caused by HSV-1 [41], but recurrences and subclinical viral shedding are much less frequent for genital HSV-1 infection than genital HSV-2 infection [42,43]. It is recommended that any non-validated diagnostic tests should be validated against a recommended, approved gold standard test. These episodes usually last less than 10 days, but may be prolonged as a result of secondary bacterial infection or immunosuppression. Sexual transmission of HSV most often produces infection of the genital mucosa, genital skin (penile and labial) and the perigenital region. In most cases of genital herpes (80–90%) the disease progresses subclinically, but may become symptomatic at any time [5,6].
Virus from genital secretions can also infect other areas, including the eyes and oro-pharynx and rectal mucosa [3,4]. The incubation period of both HSV-1 and HSV-2 is usually from two to 10 days (up to four weeks).
