Genital herpes is a type of sexually transmitted disease. If you contract genital herpes, first and foremost, you should avoid sexual contact to prevent transmitting it to others. Secondly, it’s important to rest and eat a light diet. Try to avoid smoking, drinking alcohol, or consuming particularly spicy foods, as these can also aid in recovery from the illness. Thirdly, treatment can include oral antiviral medications since genital herpes is an infection caused by the herpes simplex virus, mainly type 2. Therefore, antiviral medications such as acyclovir, valacyclovir, and famciclovir should be taken. Additionally, topical antiviral treatments, such as acyclovir ointment and penciclovir cream, can be used. If the blisters rupture and secondary infection occurs, antibiotic ointments like mupirocin should be applied to prevent further aggravation of the infection.

How long is the incubation period for genital herpes?

The incubation period of genital herpes generally ranges from 2 to 14 days, with an average of 3 to 5 days, meaning that patients might not exhibit any symptoms during the incubation period. After this period, erythema can appear around the external genitalia, followed by the development of papules, vesicles, erosions, ulcers, and crusts, which may be accompanied by pain, burning sensations, and itching. The local lymph nodes may swell, and some patients may experience headaches, fever, and fatigue as systemic symptoms.

Can genital herpes be completely cured without recurrence?

Genital herpes is difficult to completely cure without recurrence because the virus from the previous herpes outbreak resides at the sacral nerve root. When resistance is low, typically during times such as drinking alcohol and staying up late, the herpes virus travels to the area served by the sacral nerve, such as the external genitals, buttocks, and perineal region, causing blisters. Therefore, it is very difficult to completely eliminate genital herpes so that it never recurs, but the likelihood of recurrence generally decreases significantly after five to six years. Therefore, what we need to do is mainly to enhance our immune function. We can use some medications to help boost immunity, and we should also try to drink less alcohol and get more sleep.

Can genital herpes be completely cured?

Genital herpes is a chronic, recurrent, and difficult to cure sexually transmitted disease caused by the infection of the herpes simplex virus in the urogenital and perianal skin and mucous membranes. Currently, there is a lack of drugs in clinical practice that can kill the herpes simplex virus, and also a lack of methods to kill the virus, therefore genital herpes cannot be completely cured.

How is genital herpes tested?

Herpes viruses are generally divided into two types, type 1 and type 2 genital herpes, mainly caused by type 2 herpes virus. The best approach for type 2 herpes virus is to use blister fluid for PCR testing of DNA. If testing is not possible, you can also consider blood tests for herpes virus antibodies. If the IGM for type 2 herpes virus is positive, then consider it a current symptomatic infection. If the IGM is negative, but HCG is positive, then consider this herpes as a past infection.

Is blood testing for genital herpes accurate?

Genital herpes testing, blood tests generally reflect antibodies, which have a certain window period. If genital herpes has just occurred, and blisters have just formed, it is very possible that the antibodies are still negative, but the disease has already manifested. Or, the genital herpes may have healed, but the antibodies are positive. Therefore, blood tests can generally only diagnose past infections and are not very accurate for current infections. Thus, the best method for testing genital herpes is to collect blister fluid for DNA testing using PCR methods when blisters are present. This approach is the most accurate, while blood tests can only serve as a reference.
