Learning about STIs and their impact is a powerful step toward protecting your health and your community. Explore the sections below to learn more about HIV, syphilis, and hepatitis C.

What are Sexually Transmitted Infections?

Sexually Transmitted Infections (STIs) are infections caused by viruses, bacteria, fungi, or parasites that are most often spread through sexual contact, including vaginal, anal, and oral sex. Some STIs can also be spread through skin-to-skin contact, bodily fluids (such as blood, semen, or vaginal fluids), or from a parent to a baby during pregnancy or birth.

You may also hear the term STD (sexually transmitted disease). People often use STI and STD to mean the same thing. An STI may be called an STD if it begins to cause symptoms or other health problems.

Many STIs do not cause symptoms right away, so a person may not know they have one. The only way to know for sure if you have an STI is to get tested. Without testing and treatment, some STIs can lead to serious health problems over time. The good news is that many STIs can be prevented, treated, or managed with the right care and medicine.

Let’s go into the specifics!

Understanding the basics is important, but each STI has its own symptoms, transmission, and treatments.
