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
