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 in women heal by itself?

Genital herpes has an intermittent onset because herpes cannot be said to be cured and never recurs. The herpes virus congregates at the sacral nerve roots in the human body. Therefore, when immunity is low, the virus travels along the sacral nerve root to the surface of the skin, causing damage in spots, commonly known as a recurrence of herpes. Thus, genital herpes does not heal on its own; it is merely in a quiescent phase of an outbreak. Therefore, genital herpes is generally harder to treat in females than in males because the female body has a cavity, and herpes inside the cavity may not be visible.

Genital herpes is what kind of situation?

Genital herpes is caused by infection with the herpes simplex virus and is classified as a sexually transmitted disease (STD). It primarily occurs after sexual contact, although infection can also happen through contact with contaminated towels or bed sheets. Initially, small blisters appear on the external genitalia, accompanied by a burning sensation and pain. Once the disease manifests, it is contagious and can be transmitted to others through sexual contact. It is crucial to seek prompt treatment at a reputable hospital upon discovering this condition. Standard antiviral medications can cure it, but the virus cannot be completely eradicated once contracted. When immunity is low or after consuming spicy and irritating foods, the disease may recur in the genital area and become active again. Therefore, it is essential to avoid sexual contact during an outbreak to prevent repeated cross-infection.

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.
