What is Chime In?
CDC awarded the Oregon Health Authority (OHA) funding to implement the National HIV Behavioral Surveillance (NHBS) survey in the Portland-Vancouver-Hillsboro Metropolitan Statistical Area (MSA). This includes Clackamas, Columbia, Multnomah, Washington and Yamhill Counties in Oregon and Clark and Skamania Counties in Washington. NHBS is known locally as “Chime In.”
The project consists of 500 annual, anonymous surveys and HIV testing of populations at increased risk for HIV. The survey gathers information on sexual and drug use behaviors, use of prevention services, and HIV care. The target population for this project rotates annually among three groups:
- Heterosexuals at increased risk for HIV
- Men who have sex with men (including cis men, trans men and nonbinary individuals assigned male at birth)
- People who inject drugs.
This year (2025), Chime In is conducting confidential health surveys that include in-person HIV testing with heterosexuals at increased risk for HIV in the project area. Participants will receive:
- An incentive for completing an interview and completing an HIV test
- Referral to healthcare and social services as needed
- Information on HIV/AIDS and other sexually transmitted infections
