What are STIs?
Sexually transmitted infections (STIs) are viruses, parasites, or bacteria that are transmitted through sexual activity via bodily fluids or intimate skin-to-skin contact. This includes oral, vaginal, and anal sex. Anyone who is sexually active can get an STI- and they are very common, especially among young people. In fact, people who are 15-24 account for half of new STI infections each year!
