Two new studies show that jails can contribute enormously to coronavirus case totals outside their walls. Depending on the social distancing measures put in place, community spread from infections in jails could add between 99,000 and 188,000 people to the virus’ U.S. death toll, according to a modeling study recently published by the American Civil Liberties Union in conjunction with researchers from the University of Pennsylvania, the University of Tennessee and Washington State University.
