This initial post highlights key federal actions in response to the coronavirus disease 2019 (COVID-19)—through March 19, 2020—relating to public health broadly and individual health care. We discuss three sets of federal actions—(1) a federal legislative package focused on public health infrastructure, (2) a declaration of national emergency that opened the door for the state to apply for increased flexibility in the delivery of Medicaid services, and (3) a federal legislative package that provides for increased federal Medicaid funding and universal coverage of COVID-19 testing without cost sharing.
