STDs are very common. In addition to HIV, there are dozens of other types of sexually transmitted diseases. Often there are no symptoms, at least not at first. Left untreated, STDs can cause serious health issues. 

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

While routine testing for many STDs is recommended, that does not mean it always happens as part of a regular checkup or gynecologist exam. To know for sure, ask to be tested.

Scroll on for more about specific STDs, including symptoms, testing and treatment.

A healthcare provider can advise on which STDs you should be tested for and how often. If you don’t have a regular provider, free or low cost STD testing is available in most areas.
