Human herpesvirus 1 (HHV-1), also known as herpes simplex type 1 (HSV-1), is the virus that typically causes cold sores, also known as fever blisters. 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.

A characteristic feature of all herpesviruses is their ability to become latent, primarily in ganglia of the nervous system and lymphoid tissue.


Virologic analysis of endoneurial fluid obtained during decompression surgery revealed HSV-1 DNA in 11 out of 14 patients with Bell's palsy.
Primary HSV-1 infection often results in painful skin or mucosal lesions, but can also be asymptomatic. HSV-1 from postmortem explants of human trigeminal,[7,8] nodose, vagal[9] and ciliary[10] ganglia. Neurons are the exclusive site of HSV-1 latency in human ganglia, and also in mouse and rabbit models.
DNA is endless—that is, circular or concatameric[16]—and does not integrate into the host genome. In ganglia latently infected with HSV-1, only one region of the viral genome is abundantly transcribed.
Herpes simplex is a highly contagious viral infection characterized by blisters around the mouth (so-called cold sores, or fever blisters), lips, or genitals. While every effort has been made to follow citation style rules, there may be some discrepancies. Also known as a cold sore, this lesion is caused by the contagious herpes simplex virus Type-1 (HSV-1), and should not be confused with a canker sore, which is not contagious. Factors such as stress, sun exposure, surgery, illness, and fever can cause the virus to reactivate and lead to an outbreak of new sores.
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.
Increased CSF antibody to HSV-1, and a reduced serum:CSF antibody ratio, might help to diagnose HSV-1 encephalitis. Right, Coronal section showing mesial temporal lobe, insular necrosis in a case of herpes simplex virus (HSV) encephalitis.
A precontrast CT scan showing a case of herpes encephalitis, notice the left medial temporal hemorrhagic zone surrounded by edema. Cold sores and fever blisters may occur inside the mouth, on the lips, or on the area around the mouth.
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. Although they are annoying and the sores can be painful, oral herpes outbreaks are not dangerous in healthy people.
People who have compromised immune systems may suffer more serious complications from oral herpes outbreaks and should seek medical treatment.
