Herpes is a very common infection caused by a virus, called the herpes simplex virus, or HSV. The course and symptoms of herpes infections vary widely from being completely asymptomatic throughout a person's life in 80% of patients, to having frequent recurrences. HSV-1 is typically spread via infected saliva and initially causes acute herpetic gingivostomatitis in children and acute herpetic pharyngotonsillitis in adults. Acute herpetic pharyngotonsillitis is the most common first presentation of the disease in adults, and more commonly affects the pharynx and tonsils than the mouth and lips. Although genital herpes is usually caused by HSV-2, it can also be caused by HSV-1 (for instance by contact of a mouth lesion on genital skin of a non-infected person). The good news is that a person who already has antibodies to HSV-1 because of a prior infection with oral herpes causes a milder effect of genital HSV-2 and protects against acquiring HSV-1 in the genital area.


It's a good idea to go in to see your doctor if you are worried that you may have contracted herpes. Although prior research in animal models suggested that thymidine kinase-negative HSV isolates have decreased virulence[12], several reports have shown that acyclovir-resistant HSV can cause significant clinical disease in humans[10,11,12,13]. Once a person acquires the herpes virus, it invades and replicates in the nervous system, remaining deep within a nerve for life.
Along with ruptured vesicles in the tonsils and pharynx, an adult with newly acquired herpes type 1 can have fever, headache, fatigue, and sore throat. There are many over-the-counter medications and home remedies that claim to help or cure herpes, but most of these are false claims and do very little, if anything at all, to help. The herpes thymidine kinase is a 376-amino-acid protein encoded by the UL23 gene and the herpes DNA polymerase is a larger protein (approximately 1,200-amino-acids long) and it is encoded by the UL30 gene[6].

As in oral herpes, each outbreak starts with a feeling of pain or burning at the site, followed by a localized patch of vesicles that can be very painful. Acyclovir triphosphate, the active form of acyclovir, is present in 40- to 100-fold higher concentrations in herpes simplex virus (HSV)-infected cells than in uninfected cells.
The DNA polymerase mutants result from a mutation in the HSV pol gene that causes a decreased binding of acyclovir-triphosphate to viral DNA polymerase.


One report described a patient with fatal acyclovir-resistant HSV meningoencephalitis who developed acyclovir resistance during therapy of a persistent perirectal ulcer caused by HSV[11]. This allows the virus to replicate and not only cause recurrent disease but also to shed viral particles which can be spread to other people.
As in oral herpes, genital herpes also causes vesicles to form, which can appear on vagina, labia, buttocks, or even the cervix in women, and on the penis, scrotum, buttocks, thighs, and even urethra in men. Barrier protection such as with a condom can help prevent spread of genital herpes, but some HSV ulcers can occur outside o the area protected by the condom and still be transmitted. For most healthy people, herpes infections are a painful nuisance of recurrent blisters in a localized area.
However, in people with poor immune systems, such as organ transplant recipients or people with HIV, the virus can spread throughout the body and cause severe disease, even of the brain.
