Overview

HSV-2 is the herpes simplex type most commonly associated with genital herpes. It can cause recurrent outbreaks and is managed with antiviral therapy and counseling.

Causes and transmission

  • HSV-2 is transmitted through sexual contact with infected skin or secretions.
  • It can remain latent in nerve tissue and reactivate.

How it is assessed

  • PCR swab from an active lesion is often preferred.
  • Type-specific serology may detect past infection.

Management considerations

  • Antiviral medication for episodes or daily suppression.
  • Counseling on disclosure and risk reduction.

Prevention

  • Avoid sex during outbreaks.
  • Condoms reduce but do not eliminate risk.
  • Suppressive therapy may lower transmission risk.
