"Chosen at random, which is how asymptomatic screening works, only 1 in 2,000 people currently has the virus

Even if this increased to 1 in 500, and we assume that a test picks up 80% of true infections and gives the all-clear 96% of the time,

This would mean that, out of the 4,152 people who test positive in every 100,000, only 160 would actually have the virus."

As a technical person, I could not see the logic behind three statements. Consider re-writing them.

Otherwise a good piece. A lot of this transmission can be fought with simple measures. Wearing a mask or not going to that big party helps keep kids in school.
