Community and test people it doesnt tell you how many people actually infected right because everybody so you always some people and so to go from the sample to the truth to reality you know.

The idea for testing is really simple so imagine that you have 9 cups of beans and you know to order 2 of those bins. And you know that teacher which corps positive by being as you was cool beans and based so you might find. Time to get.
