  • Sun exposure (UV radiation)

  • Weakened immune system (HIV, chemotherapy, steroids)

Identifying personal triggers helps reduce frequency. Suppressive antiviral therapy (daily valacyclovir or acyclovir) can also decrease outbreaks and transmission risk. Consult a clinician for personalized advice.
