Let’s Stop HIV Together

The Let’s Stop HIV Together campaign includes resources and partnerships aimed at stopping HIV stigma and promoting HIV testing, prevention, and treatment. Let’s Stop HIV Together is working to reduce stigma among all Americans, prevent HIV among the hardest-hit populations, and help people with HIV stay healthy.


CDC partners extend the reach of the Let’s Stop HIV Together campaign. National organizations, public health organizations, media, and other partners help us to promote HIV awareness, prevention, testing, and treatment messaging wherever Americans live, work, play, worship, and learn. CDC provides partners with varying degrees of technical assistance, including the development of HIV prevention materials for dissemination at local events, digital resources, capacity building, strategic guidance for national and local activities, and linkages to other national and local partners. Learn more about our partners and how you can partner with us.

Websites and Social Media

CDC HIV provides current, scientifically-accurate HIV content and resources for the general public, public health professionals, and clinicians.  Let’s Stop HIV Together provides access to campaign resources for distinct audiences. The HIV Risk Reduction Tool helps people learn about the risk of getting HIV or transmitting HIV to someone else, and how to lower that risk.

CDC’s new HIV Nexus website is a one-stop hub for up-to-date resources designed to support clinicians in informing and communicating with patients, caregivers, and the community about HIV prevention, screening, and treatment. Clinicians can use HIV Nexus as a source of practical and credible information to stay abreast of the latest HIV recommendations and research, diagnose cases as early as possible, treat rapidly, and prevent new HIV transmissions.

PCB also engages with the general public, partners, and health care providers through social media, including Facebook (CDCHIV and Start Talking. Stop HIV.), Twitter (@CDC_HIVAIDS), Instagram (@stophivtogether and @Start Talking. Stop HIV.), and CDC’s YouTube account (CDC Streaming Health).

Content Development and Inquiry Response

PCB creates a wide variety of content related to DHAP’s priorities, including fact sheets, features, infographics for partners and consumers, and web content. Writer-editors and health communication specialists work with other branches to interpret their guidelines, reports, and other data for various audiences.

PCB also manages the HIV content for CDC-INFO, part of CDC’s national contact center that delivers up-to-date health information to consumers, providers, and professionals. PCB maintains prepared responses that CDC-INFO agents use to answer commonly asked questions about HIV, and PCB replies to questions that cannot be answered with a prepared response.


PCB represents DHAP at community events, HIV conferences, and other public health events to promote HIV testing, prevention, and care. Representatives from PCB staff the booths, answer questions, provide materials, and help audiences navigate online resources for information.

Research and Evaluation

PCB has a team of behavioral scientists who lead the research and evaluation activities that support the health communication activities of the branch. Activities include research and testing of ideas and messages with audiences before the development and launch of a campaign, and the process and outcome evaluation of campaigns after they launch.
