Why Are Coronavirus Cases Decreasing? Experts Say Restrictions Are Working

Following a dramatic surge of coronavirus cases between June and July, numbers across the United States have largely decreased, which experts attribute to local mask mandates and other precautionary measures, like restaurant and bar closures. Joe Gerald, an associate professor of public health policy at the University of Arizona, attributed the decrease to mask orders in the state's biggest cities, news media coverage of the heightened risk and also the closure of bars, gyms and theaters after they started reopening in May.
