Transmission of STIs

A sexually transmitted infection (STI) is an infection that you can get from having sex with a person who is infected. “Sex” can mean oral sex (mouth on genitals), vaginal sex (penis in vagina) or anal sex (penis in anus). ┬áPeople can have STIs and have no signs or symptoms of disease.

Common STI Fact Sheets

You may get symptoms from an STI or you may not. The only way to be sure is to have an STI test. If your partner tells you he or she has an STI, ask for the name of the disease. Go to your doctor, a sexual health clinic or an STI clinic to get tested and treated.

Untreated STIs

If some STIs are not treated, they can cause serious health problems for both men and women. All STIs can be passed on to anyone you have sex with. Untreated STIs also increase your risk of getting HIV (the virus that can lead to AIDS).
