OCOH is a new kind of collaborative partnership among communities. We know that the best experts about the communities we’re working in are the people who live and work in them. That’s why we’re at churches, hair salons, health fairs, grocery stores, soccer games, neighborhood centers, and more. Our goal is to combine science and community engagement (meeting, learning from, and working directly with people in the community) to discover new and better ways people can stay safe during airborne illnesses.
