Sexually Transmitted Infections

Sexually transmitted infections (STIs) can be passed from one person to another during sex. Some infections show no early signs, while others can lead to painful symptoms or even infertility. Most contraceptive methods, other than condoms, offer no protection against STIs.

Find basic facts and detailed information about common STIs, including their symptoms, treatment, and prevention.

The OPA website is currently being updated. More information on STIs will be made available.
