Florida is doing this too, it says in the fine print on the reports. If I understand it right, you get multiple tests to find out when you’re in the clear... can’t go back to work or leave isolation until negative. So one person might get multiple positives each on a different day, before getting the all-clear negative test. Each of these positives is recorded separately, counted separately.

If we knew the average number of tests one patient gets, we could divide the totals to get a truer number.

Or if the health departments and labs would give each individual a unique identifier...
