Sexually Transmitted Infections

Sexually transmitted infections, sometimes abbreviated as STIs or STDs, are common infections that spread from one person to another during sex. They're so common that most sexually active people will get at least one in their lifetime. Often there are no symptoms, but if left untreated, STIs can cause serious health issues, and in some cases, death.

Not all STIs are transmitted the same way. Some STIs, like gonorrhea and chlamydia, are transmitted by bodily fluids. Other STIs, like syphilis or herpes, are passed by skin-to-skin contact.

The good news is all STIs, including HIV, are treatable, and many are curable.

The Sexually Transmitted Disease (STD) Prevention and Control Program works to reduce the incidence of sexually transmitted diseases. By providing screening, testing, diagnosis and treatment for infected individuals, the STD program is fighting the war against sexually transmitted diseases one person at a time.
