The plan was for closing things down (two weeks would not have been long enough) while we ramped up a federally organized and coordinated testing and contact tracing effort. We did close things down, but the federal government abandoned the states and left them to create 50 separate testing and contact tracing efforts. For this reason, as we open things up we're just as vulnerable as we were back in March. Mitigating factors are the degree to which people continue wearing masks, and rising temperatures since "Each additional 1.8-degree temperature increase above that level was associated with an additional 3.1 percent reduction in the virus’s reproduction number..." (Summer weather could help fight coronavirus spread but won’t halt the pandemic.
Curiously I wonder if we could have rolling shutdowns as an opening option ... if we had sufficient testing and contact tracking ability ...
as shutdowns of 2 weeks should clear anyone self isolated as not infected, and thus able to replace workers who then self isolate for 2 weeks. Each cycle you remove and test people with symptoms and track who they contacted.
Just a thought
