Disease category
Herpes simplex infection is an infectious disease caused by herpes simplex virus (HSV), which can manifest not only in the oral and genital areas but also in the eyes, skin, etc.
Key mechanism
HSV-1 and HSV-2 are the primary causes, and the infection sites and transmission patterns may overlap. The virus is mainly transmitted through direct contact.
Main causes · related factors
The virus can remain latent in ganglia after initial infection and may reactivate depending on immune status and various stimuli, causing recurrent lesions.
Representative patterns
Representative manifestations include herpes labialis around the mouth and lesions around the genitals, buttocks, and anus, which may be accompanied by blisters, pain, or itching.
Individual differences
Symptoms and progression vary greatly among individuals, and asymptomatic infections also occur. The risk of severe disease may be higher in newborns and individuals with weakened immune function.
Diagnosis
Lesions may progress to blisters, followed by scabbing and healing; recurrences can repeat, but the frequency often decreases over time.
Management
Diagnosis is made within a broad framework that integrates the shape and location of the lesion, symptoms, and exposure history, utilizing molecular testing or culture testing of lesion specimens if necessary.
Treatment/Research Status
Test results must be interpreted according to the timing of specimen collection, the state of the lesion, and the testing method; the possibility of infection cannot always be ruled out based on negative results alone.
Read Evidence
Management focuses on symptom relief, counseling to reduce the risk of transmission, assessment of recurrence patterns, and prompt medical care for severe or high-risk situations.
Key Precautions
Antivirals can help fight the virus and may reduce symptoms and outbreaks, but the approval, standard therapy, or effect size of specific drugs cannot be concluded based solely on the data presented here.

At a Glance

Herpes simplex infection is an infectious disease caused by herpes simplex virus (HSV), which can manifest not only in the oral and genital areas but also in the eyes, skin, etc.

Representative manifestations include herpes labialis around the mouth and lesions around the genitals, buttocks, and anus, which may be accompanied by blisters, pain, or itching.

How the disease works

HSV-1 and HSV-2 are the primary causes, and the infection sites and transmission patterns may overlap. The virus is mainly transmitted through direct contact.

The virus can remain latent in ganglia after initial infection and may reactivate depending on immune status and various stimuli, causing recurrent lesions.

Variations in presentation among individuals

Symptoms and progression vary greatly among individuals, and asymptomatic infections also occur. The risk of severe disease may be higher in newborns and individuals with weakened immune function.

The broad framework of diagnosis and management

Lesions may progress to blisters, followed by scabbing and healing; recurrences can repeat, but the frequency often decreases over time.

Diagnosis is made within a broad framework that integrates the shape and location of the lesion, symptoms, and exposure history, utilizing molecular testing or culture testing of lesion specimens if necessary.

Current status of treatment

Test results must be interpreted according to the timing of specimen collection, the state of the lesion, and the testing method; the possibility of infection cannot always be ruled out based on negative results alone.

Management focuses on symptom relief, counseling to reduce the risk of transmission, assessment of recurrence patterns, and prompt medical care for severe or high-risk situations.

Antivirals can help fight the virus and may reduce symptoms and outbreaks, but the approval, standard therapy, or effect size of specific drugs cannot be concluded based solely on the data presented here.

How to read clinical trials

Clinical trial registration only demonstrates that a study existed and does not prove efficacy, positive results, approval, or standard of care. The presented NCT04313335 cannot be interpreted as evidence of the therapeutic effect of HSV.

Points to verify during clinical consultations

In clinical practice, it is important to confirm the location and onset of the lesion, whether it is a primary or recurrent occurrence, exposure during pregnancy or in newborns, immunocompromised status, current medications, and desired testing and treatment goals.
