Sexually Transmitted Diseases (STD)

The STI clinic is operated as a partnership between Cascade AIDS Project (CAP) and Clark County Public Health. We strive to provide a welcoming space for LGBTQ+ individuals to access STI and HIV screening and prevention services in Clark County. 

Cascade AIDS Project (CAP)-Clark County Public Health STI clinic provides testing and treatment services on Tuesdays. CAP also offers testing on Thursdays.

Free, confidential screening is available 10 am to 2 pm every Tuesday, by appointment only. 

Appointments are limited and will be prioritized for people who are underserved, disproportionately affected by HIV/STIs, or have barriers to care, specifically individuals who identify as Black, Latinx and/or LGBTQ+, sex workers, people who use substances, youth, and symptomatic or exposed people.

Submit a request for an appointment to CAP. CAP staff will contact individuals who complete the interest form and screen them for an appointment.

What are STI's?

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are very common. Millions of new infections occur every year in the United States.

STD Grapic

STIs are passed from one person to another through sexual activity including vaginal, oral, and anal sex. They can also be

passed from one person to another through intimate physical contact, though this is not very common.

STIs don’t always cause symptoms or may only cause mild symptoms, so it is possible to have an infection and not know it. That is why it is important to get tested if you are having sex. If you are diagnosed with an STI, know that all can be treated with medicine and some can be cured entirely.

STIs are preventable. If you have sex, know how to protect yourself and your sexual partners from STIs.

Visit the Centers for Disease Control and Prevention to learn more about STIs, HIV, and Hepatitis.

HIV treatment and prevention

People with HIV should take medicine to treat HIV as soon as possible. If taken as prescribed, HIV medicine reduces the amount of HIV in the body (viral load) to a very low level, which keeps the immune system working and prevents illness. HIV medicine can even make the viral load so low that a test can’t detect it. This is called an undetectable viral load.

Getting and keeping an undetectable viral load is the best thing people with HIV can do to stay healthy. Another benefit of reducing the amount of virus in the body is that it helps prevent transmission to others. This is sometimes referred to as treatment as prevention.
