Sexually transmitted infections (STIs)

A sexually transmitted infection (sexually transmitted disease) is a serious condition that can develop after you have sex. Common STI symptoms include itching and burning around your genital area. The good news is that most STI treatments can cure the infection, but not all types. You can get an STI again, even after treatment to cure it.
