Genital herpes is a chronic, recurrent, and difficult-to-cure sexually transmitted disease caused by the infection of the urinary and genital skin and mucosa with herpes simplex virus. It primarily affects the genitals and perineal area. In males, it commonly occurs on the foreskin, glans penis, and coronal sulcus. In females, it is often seen on the labia majora, labia minora, vaginal opening, and cervical opening. Less commonly, it can also affect areas around the anus, buttocks, and groin.

How is AIDS combined with genital herpes diagnosed and treated?

The treatment of AIDS combined with genital herpes requires the management under experienced infectious disease specialists and dermatologists. For AIDS, systematic and standardized antiretroviral therapy is necessary, involving a combination of three or more potent antiretroviral drugs. For genital herpes, antiviral drugs can be selected when necessary, and treatment should be tailored according to the actual situation. Through active management, most conditions can be well controlled.

How long will it take for genital herpes to heal after taking medication?

Genital herpes is categorized into primary genital herpes and recurrent genital herpes. Primary genital herpes refers to the first infection of the herpes simplex virus, with a treatment duration generally ranging from two to three weeks, after which symptoms disappear. Recurrent genital herpes refers to the recurrence of the condition after the primary infection lesions have subsided. Treatment typically leads to the disappearance of symptoms within seven to ten days. However, it should be emphasized that genital herpes cannot be completely cured, hence it is recurrent.

Is genital herpes serology accurate?

Serological testing for genital herpes in hospitals generally provides testing for type 1 and type 2 viruses, including IgM and IgG. Over 90% of genital herpes cases are primarily caused by type 2 virus, so the focus is typically on type 2 virus IgG and IgM. However, IgM represents an active infection, meaning a current infection stage. If IgM is negative and IgG is positive, it indicates a past infection. These results are generally accurate, but their timeliness is not as high as DNA's timeliness. Therefore, if possible, it is best to collect vesicle fluid on the first or second day of a herpes outbreak and use PCR to test the DNA for the most accurate results.

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.
