Can STIs lie 'dormant' in your body?

Sally
Age: 29

I had unprotected sex when I was in my early 20s - could I be carrying an infection and not know it?

Dr. Patrick French says

It's possible. For example, genital herpes lies dormant in the body and can reoccur at any time. There are tablets to reduce the severity of the infection but there is no real cure. The same is true for genital warts, though the body's natural defences can sometimes clear them. HIV isn't obvious either - about 31% of people with HIV don't know they have it. If you're in any doubt, you should arrange a check-up at your local GUM clinic.
