Why do mask requirements differ at the local and state level, and among different businesses, workplaces, and schools?
The authority for making mask requirements most often resides at the state and local level. The CDC issues recommendations and guidance to help inform policy decisions made at the local levels. Public health officials, employers, and schools typically consider local transmission rates of COVID-19, flu, and RSV, along with hospitalizations and hospital capacity when issuing mask guidance.
