I think we will only really know after we have antibody testing to determine the actual infection rate and thus the actual fatality rate. The local hospital here (city of 120k people) has 17 workers infected and there’s only 35 people infected outside of that hospital. Theoretically you would think those hospital workers got it from whichever of the 35 were at the hospital, and presumptively they were wearing appropriate PPE and still got infected. So it seems like it’s pretty incredibly contagious. The thing we don’t know is the actual fatality rate.
