Genital herpes is caused by infection with herpes simplex virus, usually through sexual contact with an infected partner. HSV-1 or HSV-2 enters through tiny skin or mucosal breaks and then settles in nearby nerve cells, where it can reactivate later and cause new outbreaks.
You’re at higher risk of genital herpes if you have unprotected sex with multiple partners, have a partner with known herpes, or started sexual activity at a young age. Weakened immunity, other STIs, and frequent skin irritation in the genital area also increase the chance of infection and recurrences.
Genital herpes is treated with antiviral tablets such as acyclovir, valacyclovir, or famciclovir, which shorten outbreaks and reduce pain. Mild cases may only need local care like gentle washing, loose cotton underwear, warm baths, and painkillers, while frequent or severe outbreaks may require longer suppressive antiviral therapy prescribed by a doctor.
