STIs or STDs (sexually transmitted diseases) are usually passed through sexual contact with an infected partner. They include many diseases such as HIV, chlamydia, gonorrhea, genital herpes, genital warts, hepatitis, syphilis, and others.

STDs are widespread – more than 2.5 million people in the U.S. are infected each year. Having a STI can make you more likely to get HIV.

Pre-exposure prophylaxis (or PrEP) is when people at very high risk for HIV take daily medicine to prevent HIV. PrEP can stop HIV from taking hold and spreading throughout your body. When taken daily, PrEP is highly effective for preventing HIV from sex or injection drug use. PrEP is much less effective when it is not taken consistently. 

Studies have shown that PrEP reduces the risk of getting HIV from sex by about 99% when taken daily. Among people who inject drugs, PrEP reduces the risk of getting HIV by at least 74% when taken daily. 

Services are available to persons diagnosed with an STD or people who think they may have been exposed to an STD. HIV testing is also available.
