Your local Planned Parenthood can also refer you to other qualified health care providers for screening and treatment of sexually transmitted infections. There are more than 30 kinds of sexually transmitted infections. They are transmitted in different ways.
Sexual intercourse is the highest risk activity for all types of STIs.
But some infections, such as herpes and hepatitis for example, can be passed through kissing. All sexually active women and men should be tested for STIs at least once a year. Very active people, or the partners of very active people, should be tested twice a year. If you or someone you know is sexually active and hasn't been recently tested, we urge you to make an appointment with your local Planned Parenthood for confidential testing.
