Sexually Transmitted Diseases (STD)

The Cascade AIDS Project (CAP)-Clark County Public Health STD clinic has resumed testing and treatment services on Tuesdays.

The free, confidential screening for chlamydia, gonorrhea, syphilis and HIV is available 10 am to 2 pm every Tuesday, by appointment only. Free chlamydia and gonorrhea treatment will be available for those who qualify.

Appointments are limited and will be prioritized for people who are underserved, disproportionately affected by HIV/STDs, 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.

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

Please bring a photo ID with you as our services are confidential, but not anonymous.

What are STDs?

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.

STDs 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.

STDs 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 STD, know that all can be treated with medicine and some can be cured entirely.

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

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