Lowest positive COVID-19 test rate since July ‘definitely encouraging,’ but officials give warning

Illinois public health officials on Monday reported 1,373 new COVID-19 cases and a seven-day positivity rate of 3.6% the lowest the main metric used to measure the spread of the virus has been in more than seven weeks. The rolling positivity rate has not been lower since July 25, when the metric dipped to 3.56%. The seven-day average rate of tests that come back positive is the figure experts rely on to gauge how rapidly the virus is spreading. Monday’s results were based on 35,930 test specimens processed by laboratories.
