Herpes viruses cycle between periods of active disease—presenting as blisters containing infectious virus particles—that last 2–21 days, followed by a remission period.
Herpes simplex is most easily transmitted by direct contact with a lesion or the body fluid of an infected individual. Herpetic gingivostomatitis is often the initial presentation during the first herpes infection. When symptomatic, the typical manifestation of a primary HSV-1 or HSV-2 genital infection is clusters of inflamed papules and vesicles on the outer surface of the genitals resembling cold sores. Individuals that participate in contact sports such as wrestling, rugby, and soccer sometimes acquire a condition caused by HSV-1 known as herpes gladiatorum, scrumpox, wrestler’s herpes, or mat herpes, which presents as skin ulceration on the face, ears, and neck. Primary infection typically presents as swelling of the conjunctiva and eyelids (blepharoconjunctivitis), accompanied by small white itchy lesions on the surface of the cornea. A herpetic infection of the brain that is thought to be caused by the retrograde transmission of virus from a peripheral site on the face following HSV-1 reactivation, along the trigeminal nerve axon, to the brain. HSV-2 is the most common cause of Mollaret's meningitis, a type of recurrent viral meningitis. Neonatal HSV infection is a rare but serious condition, usually caused by vertical transmission of HSV (type 1 or 2) from mother to newborn.
In patients with a weakened immune system, herpes simplex can cause unusual lesions in the skin. Symptoms may include painful swallowing (odynophagia) and difficulty swallowing (dysphagia). HSV-1 has been proposed as a possible cause of Alzheimer's disease.[13][14] In the presence of a certain gene variation (APOE-epsilon4 allele carriers), HSV-1 appears to be particularly damaging to the nervous system and increases one’s risk of developing Alzheimer’s disease. Antibodies that develop following an initial infection with a type of HSV prevents reinfection with the same virus type—a person with a history of orofacial infection caused by HSV-1 cannot contract herpes whitlow or a genital infection caused by HSV-1. Primary orofacial herpes is readily identified by clinical examination of persons with no previous history of lesions and contact with an individual with known HSV-1 infection. Until recently, serological tests for antibodies to HSV were rarely useful to diagnosis and not routinely used in clinical practice.[25] The older IgM serologic assay could not differentiate between antibodies generated in response to HSV-1 or HSV-2 infection. The risk of transmission from mother to baby is highest if the mother becomes infected at around the time of delivery (30% to 60%),[41][42] but the risk falls to 3% if it is a recurrent infection, and is less than 1% if there are no visible lesions.[43] To prevent neonatal infections, seronegative women are recommended to avoid unprotected oral-genital contact with an HSV-1 seropositive partner and conventional sex with a partner having a genital infection during the last trimester of pregnancy. Acyclovir is the recommended antiviral for herpes suppressive therapy during the last months of pregnancy. There is no method to eradicate herpes virus from the body, but antiviral medications can reduce the frequency, duration, and severity of outbreaks. There are several antivirals that are effective for treating herpes including: aciclovir (acyclovir), valaciclovir (valacyclovir), famciclovir, and penciclovir. A number of topical antivirals are effective for herpes labialis including acyclovir, penciclovir, and docosanol.[49][52] Docosanol can be purchased over the counter in Canada and the USA. Certain dietary supplements and alternative remedies are claimed to be beneficial in the treatment of herpes. Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. Many HSV-infected people experience recurrence within the first year of infection.[5] Prodrome precedes development of lesions. The causes of reactivation are uncertain, but several potential triggers have been documented. The term Herpes Simplex appeared in Richard Boulton's A System of Rational and Practical Chirurgery in 1713, where the terms Herpes miliaris and Herpes exedens also appeared. Herpes antiviral therapy began in the early 1960s with the experimental use of medication that interfered with viral replication called deoxyribonucleic acid (DNA) inhibitors.
In the Journal of Clinical Investigation,[88] Pedro Cuatrecasas states, “during the R&D of acyclovir (Zovirax), marketing [department of Burroughs Wellcome] insisted that there were ‘no markets’ for this compound. Since the creation of the herpes hype, some people experience negative feelings related to the condition following diagnosis, particularly if they have acquired the genital form of the disease.
Researchers at the University of Florida have made a Hammerhead ribozyme that targets and cleaves the mRNA of essential genes in HSV-1. Another possibility to eradicate the HSV-1 variant is being pursued by a team at Duke University.


A private company called BioVex began Phase I clinical trials for ImmunoVEX, another proposed vaccine, in March 2010.[103] A completely new approach has the "HSV-2 ICP0 live-attenuated HSV-2 vaccine" investigated by Dr. Transmission may also occur through skin-to-skin contact during periods of asymptomatic shedding. Common infection of the skin or mucosa may affect the face and mouth (orofacial herpes), genitalia (genital herpes), or hands (herpetic whitlow).
Following a primary infection, the virus enters the nerves at the site of primary infection, migrates to the cell body of the neuron, and becomes latent in the ganglion.[5] As a result of primary infection, the body produces antibodies to the particular type of HSV involved, preventing a subsequent infection of that type at a different site. It is of greater severity than herpes labialis which is often the subsequent presentations.
The only way to contract Herpes simplex virus 2 is through direct skin-to-skin contact with an infected individual.[citation needed] To infect a new individual, HSV travels through tiny breaks in the skin or mucous membranes in the mouth or genital areas.
In a monogamous couple, a seronegative female runs a greater than 30% per year risk of contracting an HSV infection from a seropositive male partner.[24] If an oral HSV-1 infection is contracted first, seroconversion will have occurred after 6 weeks to provide protective antibodies against a future genital HSV-1 infection.
The appearance and distribution of sores in these individuals typically presents as multiple, round, superficial oral ulcers, accompanied by acute gingivitis.[25] Adults with non-typical presentation are more difficult to diagnose. Laboratory tests include: culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction (PCR) to test for presence of viral DNA.
In many infections, the first symptom a person will have of their own infection is the horizontal transmission to a sexual partner or the vertical transmission of neonatal herpes to a newborn at term. Neither type of condom prevents contact with the scrotum, anus, buttocks, or upper thighs, areas which may come in contact with ulcers or genital secretions during sexual activity.
A seronegative mother who contracts HSV at this time has up to a 57% chance of conveying the infection to her baby during childbirth, since insufficient time will have occurred for the generation and transfer of protective maternal antibodies before the birth of the child, whereas a woman seropositive for both HSV-1 and HSV-2 has around a 1-3% chance of transmitting infection to her infant.[44][45] Women who are seropositive for only one type of HSV are only half as likely to transmit HSV as infected seronegative mothers. The use of valaciclovir and famciclovir, while potentially improving compliance have less well determined safety in pregnancy. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body.
Prodromal symptoms include tingling (paresthesia), itching, and pain where lumbosacral nerves innervate the skin.
Some individuals' outbreaks can be quite debilitating with large, painful lesions persisting for several weeks, while others will experience only minor itching or burning for a few days. It is said that Emperor Tiberius banned kissing in Rome for a time due to so many people having cold sores.
The original use was against normally fatal or disabilitating illness such as adult encephalitis,[71] keratitis,[72] in immunocompromised (transplant) patients,[73] or disseminated herpes zoster.[74] The original compounds used were 5-iodo-2'-deoxyuridine, AKA idoxuridine, IUdR, or(IDU) and 1-?-D-arabinofuranosylcytosine or ara-C,[75] later marketed under the name cytosar or cytorabine. Feelings can include depression, fear of rejection, feelings of isolation, fear of being found out, self-destructive feelings, and fear of masturbation.[90] These feelings usually lessen over time.
The hammerhead which targets the mRNA of the UL20 gene greatly reduced the level of HSV-1 ocular infection in rabbits and reduced the viral yield in vivo.[94] The gene-targeting approach uses a specially designed RNA enzyme to inhibit strains of the herpes simplex virus.
By figuring out how to switch all copies of the virus in the host from latency to their active stage at the same time, rather than the way the virus copies normally stagger their activity stage, leaving some dormant somewhere at all times, it is thought that conventional anti-viral drugs can kill the entire virus population completely, since they can no longer hide in the nerve cells. The National Institutes of Health (NIH) in the United States conducted phase III trials of Herpevac.[98] In 2010, it was reported that, after 8 years of study in more than 8000 women in the United States and Canada, there was no sign of positive results against the sexually transmitted disease caused by HSV-2[99] (and this despite earlier favorable interim reports[98]). Infection with the herpes virus is categorized into one of several distinct disorders based on the site of infection.
After initial infection, the viruses are transported along sensory nerves to the sensory nerve cell bodies, where they become latent and reside life-long. Barrier protection methods are the most reliable method of preventing transmission of herpes, but they merely reduce rather than eliminate risk.
Recurrent infections (outbreaks) may occur from time to time, especially in times of immune impairment such as HIV and cancer-related immune suppression.[1] However, after several years, some people will become perpetually asymptomatic and will no longer experience outbreaks, though they may still be contagious to others. More serious disorders occur when the virus infects and damages the eye (herpes keratitis), or invades the central nervous system, damaging the brain (herpes encephalitis). In HSV-1 infected individuals, seroconversion after an oral infection will prevent additional HSV-1 infections such as whitlow, genital herpes, and keratitis. Prodromal symptoms that occur before the appearance of herpetic lesions help differentiate HSV symptoms from the similar symptoms of other disorders, such as allergic stomatitis. Mothers infected with HSV are advised to avoid procedures that would cause trauma to the infant during birth (e.g.


Prodrome may occur as long as several days or as short as a few hours before lesions develop. Reactivation due to infection is the likely source of the historic terms cold sore and fever blister.
As late as 1975, a study of “Psychological morbidity in a clinic for sexually-transmitted disease” (Richard Mayou, The London Hospital)[87] does not mention herpes simplex because at that time, there was no significant morbidity problem (i.e. Much of the hysteria and stigma surrounding herpes stems from a media campaign beginning in the late 1970s and peaking in the early 1980s. The enzyme disables a gene responsible for producing a protein involved in the maturation and release of viral particles in an infected cell. Oral herpes, the visible symptoms of which are colloquially called cold sores or fever blisters, infects the face and mouth. Causes of recurrence are uncertain, though some potential triggers have been identified, including immunosuppressant drugs (see below). Treatments with antivirals can reduce viral shedding and alleviate the severity of symptomatic episodes.
Patients with immature or suppressed immune systems, such as newborns, transplant recipients, or AIDS patients are prone to severe complications from HSV infections.
Prior HSV-1 seroconversion seems to reduce the symptoms of a later HSV-2 infection, although HSV-2 can still be contracted.
When lesions do not appear inside the mouth, primary orofacial herpes is sometimes mistaken for impetigo, a bacterial infection.
Beginning antiviral treatment when prodrome is experienced can reduce the appearance and duration of lesions in some individuals. An area of human chromosome 21 that includes 6 genes has been linked to frequent oral herpes outbreaks. Vidarabine was the first systemically administered antiviral medication with activity against HSV for which therapeutic efficacy outweighed toxicity for the management of life-threatening HSV disease. There were multiple articles worded in fear-mongering and anxiety-provoking terminology, such as the now ubiquitous "attacks," "outbreaks," "victims," and "sufferers." At one point the term "herpetic" even entered the popular lexicon.
These are chemically engineered oligonucleotides or short segments of RNA, that can be made to mirror their target genetic material, namely herpes microRNAs. The previously latent virus then multiplies new virus particles in the nerve cell and these are transported along the axon of each neuron to the nerve terminals in the skin, where they are released.
Early stages of orofacial herpes and genital herpes are harder to diagnose; laboratory testing is usually required. HSV infection has also been associated with cognitive deficits of bipolar disorder,[3] and Alzheimer's disease,[4] although this is often dependent on the genetics of the infected person.
During recurrence, fewer lesions are likely to develop, lesions are less painful and heal faster (within 5–10 days without antiviral treatment) than those occurring during the primary infection.[5] Subsequent outbreaks tend to be periodic or episodic, occurring on average four to five times a year when not using antiviral therapy.
It should not be confused with conditions caused by other viruses in the herpesviridae family such as herpes zoster, which is caused by varicella zoster virus. Most infected individuals will experience fewer outbreaks and outbreak symptoms will often become less severe. Other disorders such as herpetic whitlow, herpes gladiatorum, ocular herpes (keratitis), cerebral herpes infection encephalitis, Mollaret's meningitis, neonatal herpes, and possibly Bell's palsy are all caused by herpes simplex viruses. The differential diagnosis includes hand, foot and mouth disease due to similar lesions on the skin. After several years, some people will become perpetually asymptomatic and will no longer experience outbreaks, though they may still be contagious to others. Immuno-compromised individuals may experience episodes that are longer, more frequent, and more severe. Antiviral medication has been proven to shorten the frequency and duration of outbreaks.[64] Outbreaks may occur at the original site of the infection or in proximity to nerve endings that reach out from the infected ganglia. In the case of a genital infection, sores can appear at the original site of infection or near the base of the spine, the buttocks, or the back of the thighs.
