Street Surveillance Watch: States build contact tracing armies to crush coronavirus

State governments are building armies of contact tracers in a new phase of the battle against the coronavirus pandemic, returning to a fundamental practice in public health that can at once wrestle the virus under control and put hundreds of thousands of newly jobless people back to work.

California is already conducting contact tracing in 22 counties, and it eventually plans to field a force of 10,000 state employees, who will be given basic training by University of California health experts.

Massachusetts and Ohio have partnered with Partners in Health, a global health nonprofit originally established to support programs in Haiti, to field teams of contact tracers. Maryland will partner with the University of Chicago and NORC, formerly the National Opinion Research Center, to quadruple its contact tracing capacity.
