On January 19, 2020, an urgent-care clinic inWashington State reported the first
confirmed case of coronavirus disease 2019 (COVID-19) in the United States
(Holshue et al. 2020). COVID-19 infections from travel and community
spread quickly spread throughout the country (WorldHealthOrganization 2020). By early
May, Johns Hopkins University and the Medicine Coronavirus Resource Center (2020)
estimated that more than 1,735,000 U.S. citizens had contracted COVID-19, resulting in
approximately 103,000 fatalities. Both figures constituted the most cases and fatalities of
any nation affected by the virus (Gupta et al. 2020).
