Sexually Transmitted Infections (STIs) affect people of all ages, backgrounds, and from all walks of life. STIs are most common among people ages 15 to 24. However, anyone who is sexually active can get an STI.
It is important to get tested for STIs and to get treated if you have an STI. Untreated STIs can cause serious health problems.

What to know about STIs
STIs are most often spread through sexual contact involving the genitals, mouth, or anus.
STIs often have no symptoms or mild symptoms. You can have an STI and spread it to others without knowing you are infected. A pregnant parent can pass an STI to their infant during pregnancy or childbirth.
You can protect yourself and your partners by getting tested for STIs and getting treatment if you have an STI.
You can reduce your risk for STIs by limiting the number of sexual partners you have and by using condoms correctly during sex.
Vaccines are recommended for some people to prevent hepatitis B and HPV.
