People having cold sores or HSV-1 should always wash their hands if they have touched the sore.
This is typically caused by HSV-2, but a person having HSV-1 with cold sores can transmit the virus to another healthy person causing genital herpes. L'herpes genital est une maladie infectieuse sexuellement transmissible ou indirectement par les doigts ayant ete en contact avec une autre partie du corps infectee (bouton de fievre) causee par le virus Herpes simplex (HSV) de type 1 ou 2. Elle consiste en des demangeaisons, brulures, petites cloques, plaies au niveau des organes genitaux. Le traitement consiste en des antiviraux pour diminuer la contagiosite, reduire la douleur, la duree et la frequence des crises. C'est une infection consideree sans gravite mais qui empeche les rapports sexuels pendant les poussees. Il s'agit d'un co-facteur important de transmission du virus de l'immunodeficience humaine responsable du SIDA.
Les infections genitales peuvent etre causees par le virus Herpes simplex (HSV) de type 1 ou 2 mais le HSV-2 est le plus courant (environ 70% des cas).
L'herpes pourrait etre considere comme un probleme de sante publique mais la politique en matiere de prevention est inexistante et les connaissances des medecins generaliste faibles. Il semble que pour qu'il y ait infection sur la peau par les fluides (salive ou secretion vaginale), il est necessaire que la peau soit abimee. Les cas d’auto-inoculation a partir d’un site d’infection oral ou labial anterieure a HSV-1 sont rares et arrivent le plus souvent durant la primo-infection orale (une personne a un herpes sur la bouche pour la premiere fois, touche les vesicules puis se touche le sexe). L’excretion et la transmission asymptomatique (la personne qui est contagieuse n'a aucun signe lui faisant penser qu'il a une poussee d'herpes) du virus sont frequentes surtout pour le HSV-2. La periode habituelle d’incubation (delai entre l'infection et les premiers signes) des primo-infections symptomatiques varie entre 2 et 21 jours. Les infections recidivantes se retrouvent habituellement sur le territoire des dermatomes S2 ou S3 (territoire de la peau innerve par la deuxieme ou troisieme racine sacree). Il s’agit du premier episode avec signes chez un patient n'ayant jamais ete au contact du HSV jusque-la. On observe une eruption vesiculeuse et ulcerative aux points d’inoculation du virus ou a proximite. Les problemes urinaires, y compris les retards a l’initiation de la miction ou une difficulte a uriner (dysurie), sont frequents chez les hommes et les femmes et ils peuvent durer longtemps.
Une meningite benigne est observee dans 10 a 30 % des cas de primo-infection symptomatique. Il s’agit du premier episode avec signes cliniques chez un patient ayant deja eu un contact avec le HSV, qu'il soit symptomatique ou non. La duree est habituellement moins longue, et il est rare que les symptomes interessent l’organisme entier. On peut observer une eruption vesiculeuse et ulcerative unilaterale ou bilaterale (chez les femmes) s’apparentant plutot a une infection recurrente symptomatique. Les symptomes sont moins graves et durent moins longtemps que dans le cas d’une primo-infection symptomatique. Les manifestations de l’infection se limitent generalement aux organes genitaux externes et sont unilaterales. La culture, apres prelevement au niveau de la lesion, demeure la methode de predilection a cause de sa specificite, de sa sensibilite et de sa capacite de typer la souche du virus.
L'utilisation de preservatifs ne protege pas completement du risque de transmission de la maladie, ce dernier n'etant reduit que d'environ 30%[3].
Dans tous les cas, des antalgiques peuvent etre utile et des soins d'hygienes restent utiles pour eviter une infection bacterienne surajoutee.
Le traitement anti-viral est utile pour attenuer les symptomes, les complications et l’excretion du virus, mais il n'est efficace seulement s’il est administre au debut de l’episode symptomatique. Le nouveau-ne peut etre contamine par la mere lors de l'accouchement s'il existe des lesions actives secondaire au HSV au niveau de la sphere genitale maternelle, provoquant un Herpes neo-natal aux consequences dramatiques. Si la primo-infection survient lors du troisieme trimestre, un accouchement a terme par cesarienne est imperatif, prevenant ainsi la contamination[2]. De nombreux traitements non medicamenteux ont ete proposes, a base de plantes, de complements alimentaires ou d'huiles dites essentielles. S'agissant d'une infection sexuellement transmissible, les rapports proteges voire une abstinence (si les lesions ne sont pas couvertes par le preservatif) sont conseilles lors de la phase eruptive. Dans un couple sero-discordant (une personne infectee, l'autre saine) il convient d'utiliser un preservatif pour tous les rapports car il est impossible de prevoir quand la personne infectee est contagieuse (on estime a au moins 5 a 10% des jours de l'annee le nombre de jours ou une personne positive est contaminante sans symptome). Pour un couple sero-discordant ayant des rapports non proteges, on estime a 10% de risque d'infecter le partenaire chaque annee.
Au cours des deux dernieres decennies, de nombreux efforts ont ete faits pour tenter de developper un vaccin contre l'herpes oculaire et genital. Le laboratoire AuRx n'a jamais reussi a trouver les financements pour poursuivre le developpement de son projet de traitement immunitaire[9].
Cytogenix travaillait sur le CY301 (SIMPLIVIR) (phase pre-clinique) une creme visant a annuler la capacite de reproduction du virus et son aptitude a migrer vers les cellules nerveuses, mais a gele ses etudes par manque de moyen[10]. D'autres societes ont suspendu ou abandonne leurs recherches, et notamment Chiron Corp (Novartis), Genvec[11], Tekron et Biovirus[12], Replicor[13] PowderMed et le pPJV7630 (Pfizer), ou bien encore Astellas Pharma Inc et son antiviral ASP2151. Il est probable qu'un certain nombre de petites societes de biotechnologie aient cherche a attirer des investisseurs sous de fausses promesses.

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. These guidelines were written on behalf of the STI Diagnostic Group of the EE SRH Network, which is supported by grants from the East Europe Committee of the Swedish Health Care Community, Swedish International Development Cooperation Agency (SIDA).

The HSV-1 infection occurs through interactions with other infected people in daily life and activities. They show up on the lips of the person and also in the mouth, the face and even inside the nose. They are more likely to get it when an adult kisses them or if they share common utensils or other things in a day care center and so on. We strongly advise you to get help from the doctors or professional herpes support groups in time. At our website, you will know the facts of herpes and rebuild your confidence to live a normal life, since herpes is a very common problem and is not going to kill you or cause any serious problems. L’infection est localisee au niveau des organes genitaux externes, du pubis, du perinee et des regions perianales, ainsi qu’au niveau du col de l’uterus, de l’anus ou de l’uretre, suivant le type de contact. Il faut d'abord que le virus s'installe avant de produire des eruptions, ce qui peut prendre plusieurs semaines. Elle s’effectue a plusieurs endroits au niveau des organes genitaux et elle est plus frequente dans le cas du HSV-2.
Le typage de la souche est souhaitable dans la plupart des cas pour permettre de mieux prevoir les recurrences ainsi que de fournir des renseignements pertinents sur la susceptibilite du partenaire.
Il faut traiter systematiquement et le plus tot possible , c'est-a-dire des l'apparition des signes annonciateurs d'une poussee d'herpes (demangeaisons, genes ou irritations), ce qui aiderait a reduire la frequence des crises et les douleurs afferentes.
Il ne permet pas de prevenir les recidives, sauf s'ils sont donnes de maniere prolongee[2].
La meme attitude est pronee en cas de presence de lesions d'herpes au niveau de la sphere genitale secondaire a une recidive.
Differentes approches ont ete etudiees par les chercheurs, et represente un veritable defi pour la recherche[4]. Malgre des resultats prometteurs sur les etudes animales, les essais cliniques ont ete decevants. Un certain nombre de recherches passees n'ont pas vu le jour, soit par manque de financement pour aller jusqu'au bout des essais, soit suite au rachat par un grand laboratoire, laissant planer un doute sur l’interet economique pour les grands laboratoires d'un tel vaccin. L'etude en phase I a debute en mars 2008 aux Etats-Unis sur 35 personnes[16]et les resultats ont ete devoiles en juillet 2010[17].
ImmunoVEX HSV2 est un vaccin vivant attenue qui a ete concu pour supprimer les genes qui permettent aux virus de l'herpes d'eviter le systeme immunitaire. Debut 2005, David Knipe de la Harvard Medical School[22] a developpe un vaccin sous le nom de dl5-29.
Cette technique a ete critiquee et jugee comme etant dangereux, car elle utilise l'ensemble du virus vivant plutot qu'un fragment de proteine.

Hendricks de l'universite de Pittsburg[32] qui travaille sur les reponses immunitaires au HSV-1. Le developpement de ce vaccin est poursuivi par leur societe Micro Antigen Technologies[35]. Thirty-eight percent had at least 6 recurrences during the first year and 20% had more than 10 recurrences. One month after publication, editors review all posted comments and select some for publication in the Letters section of the print version of Annals. 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].

This could include sharing the same plate and utensils or sharing a lip balm or even kissing an infected person.
It is contracted when the person comes into physical contact with the sore of the infected person. The person suffering from HSV-1 infection does not always have symptoms of sores, but the virus remains latent in the body, without a cure. La periode de latence peut parfois etre de plusieurs annees, certains patients ne presentant aucun symptome jusqu'a 20 ans apres la primo-infection.
La detection de ces derniers signe un contact anterieur avec le virus mais de maniere retardee.
Entre 1996 et 1999, le meme laboratoire avait deja teste un vaccin en phase III, le gD2t avec l'adjuvant GSK208141, sans suite.

Cela va a l'encontre de la plupart des recherches depuis les annees 1970, mais Halford fait valoir que cette technique a fait ses preuves pour les vieux vaccins pour enfants contre la rougeole, les oreillons et la rubeole. Selon les dernieres etudes, il semblerait que ce phenomene soit du a des predispositions genetiques. Les risques de contamination sont a leur maximum lors de la poussee du bouton de fievre et en particulier lorsque les vesicules sont eclates.
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.

This kind of infection tends to spread more quickly during an outbreak of sores in the infected person. The virus moves into the nerve cells and remains dormant there, waking up every now and then leading to a recurring infection.
Elles peuvent etre utilisees pour determiner si les femmes enceintes qui n’ont pas d’antecedents d’herpes symptomatique sont a risque. La recente decouverte que les cellules T permettent de differencier les individus symptomatiques et asymptomatiques pourrait conduire a un progres fondamental dans le developpement immunologique d'un vaccin contre l'herpes[7].
La molecule est present suivie par Harry Kleanthous et Simon Delagrave de Sanofi Pasteur sous le nom ACAM-529. En effet, le liquide qu’elles contiennent est porteur du virus et leur eclatement favorise la contamination. Twenty-six percent of women and 8% of men had no or 1 recurrence in year 1 of follow-up, whereas 14% of women and 26% of men had more than 10 recurrences. 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. HSV-1 can also cause genital herpes, if the person going through the condition has sexual activities at the time of the outbreak. This recurring infection could be caused by stress or fever or even sunlight or cold weather, flu and so on. They should avoid kissing children and should not come into close contact with newborn babies. However, the virus cannot survive outside the body, so the infection cannot be transmitted through a toilet seat or so on. Elle ne peut determiner naturellement s'il s'agit d'une primo infection ou d'une recidive mais peut definir le type de virus en cause (HSV 1 ou 2).
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.

The sores start recurring in the area where it first occurred and the blister then dries up after a few days, leaving behind a scab. 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. Recurrence rates are especially high in persons with an extended first episode of infection, regardless of whether they receive antiviral chemotherapy with acyclovir.
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. Men with genital HSV-2 infection have about 20% more recurrences than do women, a factor that may contribute to the higher rate of HSV-2 transmission from men to women than from women to men and to the continuing epidemic of genital herpes in the United States. 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).
