What are Sexually Transmitted Infections

Sexually Transmitted Infections (STIs) - also known as STDs, or sexually transmitted diseases - are passed from person to person during sex. You cannot get STIs through casual contact.

If you think you have an STI or that you have been exposed to an STI, STOP having sex immediately until you are tested and/or treated by a healthcare provider.

If you have an STI, you are at increased risk for getting HIV (Human Immunodeficiency Virus) if you are exposed to that virus. HIV is the virus that causes AIDS.

You can order a collection kit on this website to be tested for chlamydia, gonorrhea, and trichomonas.

You cannot get stis from:

Toilet Seats
Shaking Hands
Swimming Pools
Sharing Clothes
Sharing eating utensils
Non-intimate Kissing

There are many more resources to learn about STIs and STI-related issues. There are also ways you can anonymously notify your partner of their need to get tested.
