Similar to other herpesviridae, the herpes simplex viruses establish latent lifelong infection, and thus cannot be eradicated from the body with current treatments. [ 63 ] Treatment usually involves general-purpose antiviral drugs that interfere with viral replication, reduce the physical severity of outbreak-associated lesions, and lower the ...
A cold sore [a] is a type of herpes infection caused by the herpes simplex virus that affects primarily the lip. [1] Symptoms typically include a burning pain followed by small blisters or sores. [1]
Genital herpes is a herpes infection of the genitals caused by the herpes simplex virus (HSV). [1] Most people either have no or mild symptoms and thus do not know they are infected. [1] When symptoms do occur, they typically include small blisters that break open to form painful ulcers. [1]

The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
Earlier treatment (within 48 hours of symptom onset) improves the chances of a good recovery. Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. [16]
Symptoms of herpetic whitlow include swelling, reddening, and tenderness of the infected part. This may be accompanied by fever and swollen lymph nodes. Small, clear vesicles initially form individually, then merge and become cloudy, unlike in bacterial whitlow when there is pus. Associated pain often seems largely relative to the physical ...
Herpes esophagitis is a viral infection of the esophagus caused by Herpes simplex virus (HSV). While the disease most often occurs in immunocompromised patients, including post- chemotherapy , immunosuppression with organ transplants [ 1 ] and in AIDS , [ 2 ] herpes esophagitis can also occur in immunocompetent individuals.
