Friday saw the highest spike in COVID infections since April

More than 1,300 new infections were reported Friday driving up the Michigan's positivity rate.

Michigan health officials reported the highest single-day rate of new COVID-19 infections since late April – 1,313.

Previous spikes in new infections came with a corresponding increase in testing. That was not the case on Friday. The state only processed about 36,000 coronavirus tests on Friday, which meant the positivity rate increased to 4.25%. That’s about a percentage point higher than the average from last week.

Kalamazoo County has had 50 new cases of COVID-19 since Thursday, but no new deaths.

At the same time, the case count at Western Michigan University has more than doubled. The university reported 64 new COVID-19 infections between September 3 and 9. The school reports new infections each Friday on its website. WMU reported 40 cases during the previous period August 23 to September 2.

Nine of the new infections are student athletes, which prompted the school to abruptly suspend all sports activities last week.
