Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known by their taxonomical names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of new viruses that produce viral infections in the majority of humans.
The herpes simplex virus (HSV) is a virus. It causes two common diseases. Both diseases have painful, watery blisters in the skin or mucous membranes (such as the mouth or lips) or on the genitals. The disease is contagious, particularly when the disease is active.
- Signs and symptoms
Genital herpes is an infection by the herpes simplex virus of the genitals. Most people either have no or mild symptoms and thus do not know they are infected. When symptoms do occur, they typically include small blisters that break open to form painful ulcers. Flu-like symptoms, such as fever, aching, or swollen lymph nodes, may also occur. Onset is typically around 4 days after exposure with symptoms lasting up to 4 weeks. Once infected further outbreaks may occur but are generally milder. The
In males, the lesions occur on the glans penis, shaft of the penis or other parts of the genital region, on the inner thigh, buttocks, or anus. In females, lesions appear on or near the pubis, clitoris or other parts of the vulva, buttocks or anus. Other common symptoms include pain, itching, and burning. Less frequent, yet still common, symptoms include discharge from the penis or vagina, fever, headache, muscle pain, swollen and enlarged lymph nodes and malaise. Women often experience addition
Genital herpes can be spread by viral shedding prior to and following the formation of ulcers. The risk of spread between a couple is about 7.5% over a year. The likelihood of transferring genital herpes from one person to another is decreased by male condom use by 50%, by female condom by 50%, and refraining from sex during an active outbreak. The longer a partner has had the infection, the lower the transmission rate. An infected person may further decrease transmission risks by maintaining a
Testing peoples' blood, including those who are pregnant, who do not have symptoms for HSV is not recommended. This is due to concerns of greater harm than benefit, as there is a high false-positive rate and receiving a positive test result can cause other problems, such as relationship difficulties.
Once infected, there is no cure. Antiviral medications, such as acyclovir, valacyclovir, may prevent outbreaks or shorten outbreaks if they occur. The long-term use of antivirals may also decrease the risk of further spread. The longer a person has the virus, the fewer outbreaks they experience and the harder it will be to transmit to others, due to these specialty antigens and a strengthened immune system response. Acyclovir is an antiviral medication and reduces the pain and the number of lesi
Herpesviral encephalitis, or herpes simplex encephalitis (HSE), is encephalitis due to herpes simplex virus.It is estimated to affect at least 1 in 500,000 individuals per year, and some studies suggest an incidence rate of 5.9 cases per 100,000 live births.

Herpes labialis, commonly known as cold sores, is a type of infection by the herpes simplex virus that affects primarily the lip. Symptoms typically include a burning pain followed by small blisters or sores. The first attack may also be accompanied by fever, sore throat, and enlarged lymph nodes. The rash usually heals within 10 days, but the virus remains dormant in the trigeminal ganglion. The virus may periodically reactivate to create another outbreak of sores in the mouth or lip. The cause
The term labia means "lip". Herpes labialis does not refer to the labia of the genitals, though the origin of the word is the same. When the viral infection affects both face and mouth, the broader term orofacial herpes is used, whereas herpetic stomatitis describes infection of the mouth specifically; stomatitis is derived from the Greek word stoma, which means "mouth".
Herpes infections usually show no symptoms; when symptoms do appear they typically resolve within two weeks. The main symptom of oral infection is inflammation of the mucosa of the cheek and gums—known as acute herpetic gingivostomatitis—which occurs within 5–10 days of infection. Other symptoms may also develop, including headache, nausea, dizziness and painful ulcers—sometimes confused with canker sores—fever, and sore throat. Primary HSV infection in adolescents frequently ...
Herpes labialis infection occurs when the herpes simplex virus comes into contact with oral mucosal tissue or abraded skin of the mouth. Infection by the type 1 strain of herpes simplex virus is most common; however, cases of oral infection by the type 2 strain are increasing. Specifically, type 2 has been implicated as causing 10–15% of oral infections. Cold sores are the result of the virus reactivating in the body. Once HSV-1 has entered the body, it never leaves. The virus moves from ...
The likelihood of the infection being spread can be reduced through behaviors such as avoiding touching an active outbreak site, washing hands frequently while the outbreak is occurring, not sharing items that come in contact with the mouth, and not coming into close contact with others. Because the onset of an infection is difficult to predict, lasts a short period of time and heals rapidly, it is difficult to conduct research on cold sores. Though famciclovir improves lesion healing time, it i
Despite no cure or vaccine for the virus, a human body's immune system and specialty antigens typically fight the virus. Docosanol, a saturated fatty alcohol, is a safe and effective topical application that has been approved by the United States Food and Drug Administration for herpes labialis in adults with properly functioning immune systems. It is comparable in effectiveness to prescription topical antiviral agents. Due to its mechanism of action, there is little risk of drug resistance. The
HSV1716 is a first generation oncolytic virus developed by The Institute of Virology, Glasgow, UK, and subsequently by Virttu Biologics (formerly Crusade Laboratories, a spin-out from The Institute of Virology), to selectively destroy cancer cells. The virus has the trade name SEPREHVIR. It is based on the herpes simplex virus (HSV-1).
Herpes simplex gehört zu den sexuell übertragbaren Krankheiten. Die Erreger von Herpes-simplex-Infektionen sind zwei verschiedene Virusspezies: das Herpes-simplex-Virus 1 (HSV-1) und das Herpes-simplex-Virus 2 (HSV-2). Sie zeigen hinsichtlich ihrer Krankheitsbilder und der Krankheitslokalisation geringfügige Abweichungen.
- Infektionen durch Herpesviren [Herpes simplex]
Există două tipuri de virus herpes simplex, tipul 1 (HSV-1) și tipul 2 (HSV-2). HSV-1 cauzează mai des infecții orale, în timp ce HSV-2 cauzează mai mult infecții genitale. Sunt transmise prin contact direct cu fluidele corporale sau a unei leziuni a unui individ infectat. Transmisia poate apărea chiar dacă nu există simptome.
