What can four decades of HIV/AIDS response teach public health about preparing for the next crisis? In this episode, Dr. Eugene McCray, a physician, epidemiologist, and longtime public health leader, reflects on the lessons HIV/AIDS has taught about trust, stigma, data, prevention, equity, and community engagement. He explains how community advocacy helped accelerate surveillance, drug development, education, and access to care, and why effective interventions mean little if they do not reach the people who need them most. Dr. McCray also explores the importance of transparent communication, timely, locally relevant data, and the creation of safe environments where communities and public health teams can share concerns and solutions. Looking ahead, he argues that future public health responses must be community-centered, evidence-based, prevention-focused, and willing to take accountability when systems get things wrong. Tune in to hear why the lessons of HIV/AIDS are not simply history, but a blueprint for building more resilient public health systems. IHI Spotlight: The episode's spotlight connects the conversation to healthcare improvement, safety, equity, and public health learning. The central lesson is that public health needs memory: science and data must remain connected to people, prevention tools must be paired with systems that deliver them equitably, and community partnership must be treated as a condition for effectiveness rather than a courtesy. About Dr. Eugene McCray: Dr. Eugene McCray is a physician, epidemiologist, and public health leader whose career has contributed to the HIV/AIDS response in the United States and globally. His work has included HIV surveillance, prevention, healthcare-worker safety, global HIV programs, and leadership of the CDC's domestic HIV program. In this conversation, he draws on decades of experience to explore what public health can learn from HIV/AIDS about trust, community engagement, data, prevention, equity, and accountability. Things You’ll Learn: Community-led advocacy helped accelerate the HIV/AIDS response by strengthening surveillance, speeding drug development, and building trust with affected populations. Stigma and discrimination can undermine public health by discouraging people from testing, seeking care, and accessing services. Transparent communication is essential when science is uncertain, especially when leaders clearly distinguish what is known from what is not yet known. Public health leaders need to listen to communities and create environments where staff and community members feel safe sharing concerns, assumptions, and solutions. Data is most powerful when it is timely, local, actionable, and used to identify populations being left behind rather than to assign blame. Effective prevention tools such as PrEP cannot reduce inequities unless public health systems tailor delivery to the communities that need them and involve those communities in designing interventions. Meaningful community engagement should extend across research, implementation, evaluation, and the feedback loop that uses data to improve programs. Future public health crises will require systems that integrate trust, prevention, and accountability, take responsibility for mistakes, and build stronger community-centered partnerships.
