The Effect of Stay-at-Home Orders on COVID-19 Infections in the United States

Category:

Topic:

  • Using data on stay-at-home orders and daily confirmed COVID-19 cases at the county level in the U.S., this modeling study suggests that if a national stay-at-home order was issued on March 13 when a national emergency was declared, the number of infections and deaths may have reduced by hundreds of thousands and thousands, respectively. 
  • The authors suggest that future efforts to control pandemics in the U.S. should coordinate stay-at-home orders at the national level, especially for diseases that have already spread locally and testing availability is delayed.
