Disease category
Genital herpes is a sexually transmitted infection caused by the herpes simplex virus (HSV), which can cause lesions around the genitals, rectum, buttocks, or thighs.
Key mechanism
Transmission primarily occurs through vaginal, anal, or oral sex with an infected person, and can also be transmitted from mother to newborn during childbirth.
Main causes · related factors
HSV can remain latent in the nervous system after infection, and subsequent reactivation can cause recurrent lesions or asymptomatic viral shedding.
Representative patterns
A typical presentation involves painful blisters that rupture to appear like ulcers and then gradually heal.
Individual differences
Symptoms may be absent or very mild, but a more serious course of disease can occur in newborns and immunocompromised individuals.
Diagnosis
The virus remains in the body for life, and recurrences are particularly common in the first year, but the frequency of recurrence and severity of symptoms often decrease over time.
Management
Diagnosis primarily relies on viral testing or molecular testing using lesion specimens when lesions are present, and blood tests may be considered depending on the situation.
Treatment/Research Status
Since asymptomatic infections are common, it is difficult to rule out all possibilities of infection based solely on negative results when no lesions are present, and interpretation varies depending on the type and timing of the test.
Read Evidence
Management focuses on reducing symptoms and recurrences and lowering the risk of transmission; it also involves reviewing methods for avoiding sexual contact and correctly using barrier contraception when lesions or prodromal symptoms are present.
Key Precautions
Current treatment is based on antiviral therapy aimed at symptom relief, reduction in recurrences, and reduction in transmission risk rather than a cure, and there is no established cure.

At a Glance

Genital herpes is a sexually transmitted infection caused by the herpes simplex virus (HSV), which can cause lesions around the genitals, rectum, buttocks, or thighs.

A typical presentation involves painful blisters that rupture to appear like ulcers and then gradually heal.

How the disease works

Transmission primarily occurs through vaginal, anal, or oral sex with an infected person, and can also be transmitted from mother to newborn during childbirth.

HSV can remain latent in the nervous system after infection, and subsequent reactivation can cause recurrent lesions or asymptomatic viral shedding.

Variations in presentation among individuals

Symptoms may be absent or very mild, but a more serious course of disease can occur in newborns and immunocompromised individuals.

The broad framework of diagnosis and management

The virus remains in the body for life, and recurrences are particularly common in the first year, but the frequency of recurrence and severity of symptoms often decrease over time.

Diagnosis primarily relies on viral testing or molecular testing using lesion specimens when lesions are present, and blood tests may be considered depending on the situation.

Current status of treatment

Since asymptomatic infections are common, it is difficult to rule out all possibilities of infection based solely on negative results when no lesions are present, and interpretation varies depending on the type and timing of the test.

Management focuses on reducing symptoms and recurrences and lowering the risk of transmission; it also involves reviewing methods for avoiding sexual contact and correctly using barrier contraception when lesions or prodromal symptoms are present.

Current treatment is based on antiviral therapy aimed at symptom relief, reduction in recurrences, and reduction in transmission risk rather than a cure, and there is no established cure.

How to read clinical trials

The registration or completion of a clinical trial only indicates that research was conducted; it does not prove efficacy, safety, approval, or standard of care, so result papers and study designs must be verified separately.

Points to verify during clinical consultations

In clinical practice, it is possible to confirm the onset and characteristics of lesions, frequency of recurrence, pregnancy status, immune status, recent sexual contact and partner symptoms, desired tests, and preventive counseling.

Medical Guidance

This material is for educational purposes and is not intended as a guide for individual diagnosis or treatment. Consult with medical professionals regarding judgments related to symptoms, pregnancy, immune status, or test results.

Evidence and sources

A trial registry status does not establish efficacy or regulatory approval.
