Genital HSV is the most common sexually transmitted infection (STI) in both men and women, but as many as 90% don’t know they are infected because their symptoms are too mild to notice or mistaken for another condition. Symptomatic genital herpes is characterized by a burning and itching sensation in the genitals, followed by blistering.
HSV skin lesions usually appears as small blisters or sores around the mouth, nose, genitals, buttocks, and lower back, though infections can develop almost anywhere on the skin. This photo shows HSV-1 lesions on the buttock of a five-year-old girl — also called sacral herpes simplex. Herpetic whitlow is an intensely painful infection of the hand involving 1 or more fingers that typically affects the terminal phalanx.
Serologic testing for HSV has limited value in acute clinical diagnosis because of the time delay for seroconversion following initial infection.
Acyclovir, valacyclovir and famciclovir are the most commonly used agents for treating HSV infections.
A wide disparity exists between the public and medical community regarding the significance of herpes infections. The majority of recurrent oral herpes cases are caused by herpes simplex virus type 1 (HSV-1) and the majority of genital herpes cases are caused by HSV-2. Differentiating between the two types of infection using either type specific swab testing, preferably PCR, or type specific IgG antibody testing, is very important because HSV-1 genitally recurs less, is shed less, and presents far less risk of transmission to others than HSV-2. Fifty seven percent of Americans between 14 and 49 have HSV-1, and 16% of the same group has HSV-2 infection. HighlightsHerpes VirusesHerpes simplex virus 1 (HSV-1) is the main cause of herpes infections that occur on the mouth and lips. TransmissionTo 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 area. Unfortunately, only 5% of infected pregnant women have a history of symptoms, so in many cases herpes infection is not suspected, or symptoms are missed, at the time of delivery. Eczema HerpeticumA form of herpes infection called eczema herpeticum, also known as Kaposi's varicellaform eruption, can affect patients with skin disorders and immunocompromised patients.
Herpes in Patients with Compromised Immune SystemsHerpes simplex is particularly devastating when it occurs in immunocompromised patients and, unfortunately, co-infection is common. Herpes simplex virus (HSV-2, DNA virus) in cellular vacuoles and cytoplasm of peripheral blood lymphocyte (Herpesviridae Family).

In women who contract the disease, the cervix is infected 80% to 90% of the time during primary infection. This photo shows a close-up of lesions on the upper eyelid in a 20-year-old male patient due to HSV-1. Of patients who develop seropositivity, 65% do so within six weeks, while approximately 20% do not make antibodies for six months. While all three drugs decrease the duration and severity of illness and viral shedding, they have no effect on nonreplicating viruses, nor do they eliminate the virus from the ganglia. Although treatment options exist, respondents in one survey considered contracting herpes as worse than breaking up with a significant other, getting fired from a job, or failing a course in school. HSV infection is a persistent and chronic infection of the sensory ganglia with a varying, unpredictable degree of skin expression.
Both viruses can be carried in bodily fluids (such as saliva, semen, or fluid in the female genital tract) or in fluid from herpes sores.
If there is evidence of an active outbreak, doctors usually advise a Cesarean section to prevent the baby from contracting the virus in the birth canal during delivery.Approach to the Pregnant Herpes Patient.

Primary infections can range from subclinical to severe, with fever, headache, malaise, anorexia, pain, lymphadenopathy and edema.
Clinical recurrence occurs on average 3 to 4 times a year, but some patients experience monthly outbreaks.
Cervical infection alone is rarely symptomatic, but because the cervix is not sensitive to pain, infection may pass unnoticed. Be sure to provide adequate counseling to help patients put their diagnosis in perspective. This slideshow will highlight variations in presentation and provide more information about diagnosis and treatment.
The risk for infection is highest with direct contact of blisters or sores during an outbreak.Once the virus has contact with the mucous membranes or skin wounds, it begins to replicate. Microscopy photographs (science images, electron microscope images, photomicrographs, microscopy photos, microscope photos, microscopic pictures) are available for use in editorial and commercial formats. The risk of infection is highest during outbreak periods when there are visible sores and lesions.
The virus is then transported within nerve cells to their roots where it remains inactive (latent) for some period of time. Scarring and corneal thinning develop, which may cause the eye's globe to rupture, resulting in blindness. Centers for Disease Control and Prevention (CDC) recommends that all patients diagnosed with HSV-2 should be tested for HIV.The majority of patients with HIV are co-infected with HSV-2 and are particularly vulnerable to its complications. Image categories include Algae, Arachnids, Bacteria, Crystals, Fungi, Insects, Invertebrates, Medical, Miscellaneous, Plants, Protozoa, Vertebrates and Viruses. Samples are cultured to detect the virus at 3 - 5-day intervals prior to delivery to determine whether viral shedding is occurring. No images or graphics on this site may be used without written permission of their respective owners.


However, at some point, it often begins to multiply again without causing symptoms (called asymptomatic shedding). If no lesions are present and cultures indicate no viral shedding, a vaginal delivery can be performed and the newborn is examined and cultured after delivery.Some doctors recommend anti-viral medication for pregnant women who are infected with HSV-2.
Iridocyclitis is another serious complication of ocular herpes, in which the iris and the area around it become inflamed.GingivostomatitisHerpes can cause multiple painful ulcers on the gums and mucous membranes of the mouth, a condition called gingivostomatitis.
During shedding, the virus can infect other people through exchange of bodily fluids.Sometimes, infected people can transmit the virus and infect other parts of their own bodies (most often the hands, thighs, or buttocks). Recent studies indicate that acyclovir (Zovirax, generic) valacyclovir (Valtrex), or famciclovir (Famvir) can help reduce the recurrence of genital herpes and the need for Cesarean sections. Untreated, this condition can be extremely serious and possibly fatal.Ocular Herpes and Vision LossHerpetic infections of the eye (ocular herpes) occur in about 50,000 Americans each year. This process, known as autoinoculation, is uncommon, since people generally develop antibodies that protect against this problem.Transmission of Oral Herpes. In most cases, ocular herpes causes inflammation and sores on the lids or outside of the cornea that go away in a few days. HSV is part of a group of other herpes viruses that include human herpes virus 8 (the cause of Kaposi's sarcoma) and varicella- zoster virus (also known as herpes zoster, the virus responsible for shingles and chicken pox). However, other conditions can resemble herpes, and doctors cannot base a herpes diagnosis on visual inspection alone. HSV-1 is the most prevalent form of herpes simplex virus, and infection is most likely to occur during preschool years.
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.
In addition, many patients who carry the virus do not have visible genital or oral lesions. Herpes can also spread to internal organs, such as the liver and lungs.Infants infected with herpes are treated with acyclovir. It is important to treat babies quickly, before the infection spreads to the brain and other organs.Effects on the Brain and Central Nervous SystemHerpes Encephalitis.
In children, this is often caused by thumbsucking or finger sucking while they have a cold sore. Until recently, the general rule was to assume that HSV-1 infections occur in the oral cavity (mouth) and are not sexually transmitted, while HSV-2 attacks the genital area and is sexually transmitted. It can also occur in adult health care workers, such as dentists, because of increased exposure to the herpes virus.
It is now widely accepted, however, that either type can be found in either area and at other sites. In addition, because herpes simplex virus 1 can be passed in saliva, people should also avoid sharing toothbrushes or eating utensils with an infected person.Transmission of Genital Herpes. Genital herpes is most often transmitted through sexual activity, and people with multiple sexual partners are at high risk. The virus, however, can also enter through the anus, skin, and other areas.People with active symptoms of genital herpes are at very high risk for transmitting the infection. Fortunately, rapid diagnostic tests and treatment with acyclovir have significantly improved survival rates and reduced complication rates. The virus does not multiply, but both the host cells and the virus survive.At unpredictable times, the virus begins multiplying again. Unfortunately, evidence suggests about a third of all herpes simplex virus 2 (HSV-2) infections occur when the virus is shedding but producing no symptoms. Nearly all who recover suffer some impairment, ranging from very mild neurological changes to paralysis. Most people either have no symptoms or don't recognize them when they appear.In the past, genital herpes was mostly caused by HSV-2, but HSV-1 genital infection is increasing. Patients who are treated with acyclovir within 2 days of becoming ill have the best chance for a favorable outcome.Herpes Meningitis.
This may be due to the increase in oral sex activity among young adults.SymptomsSymptoms vary depending on whether the outbreak is initial or recurrent.
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. Unfortunately, a third to half of the times shedding occurs without any symptoms at all.Eventually, the symptoms return in most cases, causing a new outbreak of blisters and sores. This close-up view of early herpes outbreak shows small, grouped blisters (vesicles) and lots of inflammation (erythema). In fact, studies indicate that 10 - 25% of people infected with HSV-2 are unaware that they have genital herpes.
Fortunately, after lasting for up to a week, herpes meningitis usually resolves without complications, although recurrences have been reported. Even if infected people have mild or no symptoms, they can still transmit the herpes virus.Symptoms of Genital HerpesPrimary Genital Herpes Outbreak.
For patients with symptoms, the first outbreak usually occurs in or around the genital area 1 - 2 weeks after sexual exposure to the virus.
The first signs are a tingling sensation in the affected areas (such as genitalia, buttocks, and thighs) and groups of small red bumps that develop into blisters. The lesions 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, fever, and swollen glands.
The virus sheds for a much shorter period of time (about 3 days) compared to in 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 causes 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 herpes simplex virus 1 (HSV-1) but can also be caused by herpes simplex virus 2 (HSV-2).


It usually affects the lips and, in some primary attacks, the mucous 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.
In adolescents, the primary infection is more apt to appear in the upper part of the throat and cause soreness.Recurrent Oral Herpes Infection. Most patients have only a couple of outbreaks a year, although a small percentage of patients have more frequent recurrences. Recurrences are usually much milder than primary infections and are known commonly as cold sores or fever blisters (because they may arise during a bout of cold or flu).
The outbreak of infection is often preceded by a prodrome, an early group of symptoms that may include itching skin, pain, or an abnormal tingling sensation at the site of infection.
The prodrome, which may last as short as 2 hours or as long as 2 days, stops when the blisters develop.
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.Triggers of Recurrence.
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.
For most people, outbreaks recur with more frequency during the first year after an initial attack.
In most healthy people, recurring infections tend to become progressively less frequent, and less severe, over time. However, the immune system cannot kill the virus completely.Risk FactorsRisk for Oral HerpesOral herpes is usually caused by HSV-1. Centers for Disease Control and Prevention, about 1 in 6 American teenagers and adults, are infected with HSV-2. While HSV-2 remains the main cause of genital herpes, in recent years HSV-1 has significantly increased as a cause, most likely because of oral-genital sex. Except for people in monogamous relationships with uninfected partners, everyone who is sexually active is at risk for genital herpes.Risk factors for genital herpes include a history of a prior sexually transmitted disease, early age for first sexual intercourse, a high number of sexual partners, and loq socioeconomic status. Women are more susceptible to HSV-2 infection because herpes is more easily transmitted from men to women than from women to men.
African-American women are at particularly high riskPeople with compromised immune systems, notably patients with HIV, are at very high risk for HSV-2. This group is at higher than average risk for herpetic whitlow, herpes that occurs in the fingers.Wrestlers, rugby players, and other athletes who participate in direct contact sports without protective clothing. These individuals are at risk for herpes gladiatorum, an unusual form of HSV-1 that is spread by skin contact with exposed herpes sores and usually affects the head or eyes.Preventing TransmissionInfected people should take steps to avoid transmitting genital herpes to others. It is almost impossible to defend against the transmission of oral herpes since it can be transmitted by very casual contact.Genital herpes is contagious from the first signs of tingling and burning (prodrome) until the time that sores have completely healed. While condoms may not provide 100% protection, they have been proven to significantly reduce the risk of sexual disease transmission. 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 (such as K-Y Jelly, Astroglide, AquaLube, and glycerin) should be used. Oil-based lubricants (such as petroleum jelly, body lotions, and cooking oil) can weaken latex. However, it is best not to use condoms pre-lubricated with spermicides.Do not use spermicides for protection against herpes. If you do, be sure to immediately wash your hands with hot water and soap.The herpes virus does not live very long outside the body.
While the chances of transmitting or contracting herpes from a toilet seat or towel are extremely low, it is advisable to wipe off toilet seats and not to share damp towels.Recent studies have suggested that male circumcision may help reduce the risk of HSV-2, as well as human papillomavirus (HPV) and HIV infections. Except in very rare instances and special circumstances, HSV is not life threatening.Herpes and PregnancyPregnant women who have genital herpes due to either herpes simplex virus 2 (HSV-2) or herpes simplex virus 1 (HSV-1) have an increased risk for miscarriage, premature labor, inhibited fetal growth, or transmission of the herpes infection to the infant either 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 - 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. Transmission can occur if the amniotic membrane of an infected woman ruptures prematurely, or as the infant passes through an infected birth canal. This increased risk is present 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. Also rarely, newborns may contract herpes during the first weeks of life from being kissed by someone with a herpes cold sore.
Infants may get congenital herpes from a mother with an active herpes infection at the time of birth.
Aggressive treatment with antiviral medication is required, but it may not help systemic herpes.
