Education and Prevention


The mission of the HIV/AIDS and STD Program is to prevent the spread of HIV and other sexually transmitted diseases (STDs), as well as to reduce the impact of these diseases by coordinating countywide education, prevention, testing and care services. We work in partnership with individuals, groups and community-based organizations using a variety of strategies to link education, testing, counseling and referral services with the health care.

HIV/AIDS Testing Services

Testing is available through the HIV/AIDS Program, STD clinic and school-based health clinics.

Sexually Transmitted Disease (STD) Testing

We offer testing and treatment for sexually transmitted diseases at three locations throughout the County every week. Call 1-800-479-9664 to make an appointment. Contra Costa Health Services also provides STD and HIV education and testing to young people at various sites throughout the County.

Partner Counseling and Referral Service (PCRS)

HIV Disclosure assistance can help you talk with your partner about your HIV status. Call 925-313-6771 for more information or to schedule a private appointment.

Support Groups

Support groups are ongoing meetings which allow people to connect with each other, mutually support one another while they explore their risks for HIV and develop skills in risk reduction or prevention.

Prevention with Positives (PWP)

Prevention with positives is one-on-one counseling that helps people with HIV make a plan to prevent transmission of HIV to others while maintaining their own health. Referrals to the program are made based on an individual's needs.

Needle Exchange

One for one needle exchange is available at locations throughout the County. Needle exchange provides clean syringes, condoms, and health education, referrals and harm reduction information to participants.

Non-Prescription Sale of Syringes

Non-prescription sales of syringes (NPSS) at local pharmacies are a powerful intervention for prevention of blood borne infections (namely HIV and hepatitis B and C) among injection drug users and their sexual partners.

Post Exposure Prophylaxis Information

HIV post-exposure prophylaxis (PEP) is the initiation of antiretroviral drugs within 72 hours after a high-risk exposure to HIV, to reduce (but not eliminate) the possibility of HIV infection. PEP is not the morning after pill for HIV. PEP is a four-week program antiretroviral medication. The medications have serious side effects that can make it difficult to finish the program. If you have been exposed to HIV through rape or a needle stick, go to an emergency room. Follow up with your medical care provider for more information.
