Overview
Genital herpes is caused by herpes simplex virus, usually HSV-2 but sometimes HSV-1. It can cause recurrent sores and is managed with antiviral medication, counseling and prevention strategies.
Causes and transmission
- HSV-2 is more commonly associated with genital herpes, but HSV-1 can also cause genital infection through oral-genital contact.
- The virus can remain dormant and reactivate.
How it is assessed
- Active lesions may be swabbed for PCR or culture.
- Blood tests can detect HSV antibodies but may not distinguish recent from past infection.
Management considerations
- Antiviral medication can shorten episodes or reduce recurrence.
- Counseling addresses transmission risk and disclosure.
Prevention
- Avoid contact during active lesions.
- Suppressive therapy may reduce but not eliminate transmission risk.
- Condoms reduce risk when covering affected areas.
Key points
- Caused by HSV-1 or HSV-2
- Can recur after initial infection
- Testing interpretation can be complex
- Suppressive therapy may help
When to seek care
- Recurrent blisters or ulcers
