This corona virus swept through much of California back in January/February. My wife was sick for a few weeks back in early Feb, bad enough to go to the doctor, but they weren't doing tests back then so didn't diagnose the virus.

We also had 25% of our caregivers out horribly sick with the same symptoms all in the same time frame. Contagious as hell.

This tells me there are a lot of people that have already fought off the China virus and can return to work and normal life.
