"One of the hallmark features of any new public health crisis like COVID-19 is that things are highly uncertain," Levine said. "Public health inherently entails collective action, and very diverse people need to find a way to work together," he said. He points to partnerships that proved vital during COVID-19, from health departments working with schools and social workers to sanitation workers and state officials. "Cross-sector collaboration is vital to public health, but it depends on people already knowing how to relate to each other, speaking the same language, and trusting each other," Levine said. Ask yourself: What kinds of collaborative relationships do we need to protect public health in the communities I am part of?
