From the article:
The warning comes nearly a month after Connecticut public health officials first reported that at least 90 people had received false-positive results for the coronavirus.
A MONTH?!?!?
How many thousands have a false positive over the course of that month?
How many thousands in the time the test was in use previous to the one month that was noticed?
