Overview
Genital herpes is a common sexually transmitted infection caused by the herpes simplex virus, which produces painful blisters and sores in the genital area. Like cold sores, the virus stays in the body for life and flares from time to time, though attacks usually become milder over the years. Many people have few or no symptoms yet can still pass it on. It cannot be cured, but antiviral medicines control outbreaks and reduce spread, and testing and honest conversations with partners matter.
Symptoms
- Painful blisters or sores around the genitals or anus
- Tingling, itching or burning before an outbreak
- Pain when passing urine if sores are near the urethra
- Flu-like symptoms with the first outbreak
- Recurring, usually milder, outbreaks over time
When to see a doctor
See a doctor for genital sores or pain, or if you may have been exposed — antiviral treatment controls outbreaks and lowers the risk of spreading it.
Causes
The herpes simplex virus, spread through skin-to-skin and sexual contact, including when the person has no visible sores.
