This shows the # of Positive cases (each person only counted once) divided by the total # of persons tested (ignores multiple neg/pos tests)
It's purely how many people have tested positive out of all people tested

They should include ALL tests, whether negative or positive but excluded multiple tests per day. Don't exclude people who previously tested positive.
They're still positive and potentially contagious.
