In the absence of a vaccine, prevention is composed of a combination of nonpharmacological interventions for suppression of transmission to R0 <1 and mitigation of the number of patients with COVID‐19 who require intensive care and mechanical respiratory support. 12  Interventions include improved personal hygiene promotions, symptomatic screening and laboratory testing for case detection, contact tracing, household quarantine of those with transmission risks, and social distancing (Table 3). The United States and most other countries have implemented extensive travel restrictions, workplace and school closures, and cancellation of sporting and other large public events. China, South Korea, and Taiwan successfully curbed large COVID‐19 epidemics with prompt scale‐up of testing, contact tracing, and quarantine. 2 ,  4 ,  7  In the United States, although testing rates are low, models suggest prevention measures are reducing transmission and future deaths. 13  The US government recently recommended increased COVID‐19 surveillance, testing, and contact tracing with modified social distancing measures to sustain SARS‐CoV‐2 prevention while opening up education and commerce. 14
