What's the point?

If you have a fever and are coughing and sneezing - stay home!

If your fever is high or you are having trouble breathing - see a doctor.

If someone you spend a lot of time around is sick, wear a good mask and avoid people as much as possible for a few days to make sure you don't have it too.

Or, are we supposed to be testing asymptomatic people? If so, then we're going to need a lot more than four.
