Sexually transmitted infections (STIs) are very common infections due to bacteria, parasites, yeast, and viruses.
STIs are transmitted from one person to another through sexual activity including vaginal, oral, and anal sex.
STIs don’t always cause symptoms or may only cause mild symptoms, so it is possible to have an infection and not know it. That is why it is important to get tested if you are having sex. If you are diagnosed with an STI, know that all can be treated with medicine and some can be cured entirely.
STIs are preventable. If you have sex, know how to protect yourself and your sexual partner from STIs.
