Contract tracing of MA health care workers have found that the vast majority, but not all, of infections were passed by community spread, which means not in the hospitals.
Which means people were not being socially distant and were being in lengthy enough close contact to assume a viral load big enough to infect when not at work.
But of course, everyone can't wear protective gear at a hospital level everywhere all the time, either.
So there is a middle ground of some prevention to try to reduce the transmission rate to extinguish the virus.
