Michigan coronavirus data for Monday, April 19: Two hopeful signs in the numbers Updated 9:08 AM; Facebook Share After weeks of unnerving increases in new coronavirus cases and positivity rates in Michigan, there are a couple signs the numbers may be cresting. The most hopeful sign: The statewide positivity rate on coronavirus diagnostic tests is dropping. It was 12.1% for test results reported Friday, April 16, with a seven-day average of 14.3%. The former was the lowest one-day rate since March 26, and the latter was the lowest since April 1. The number of daily new cases also seems to be plateauing: The seven-day average rose only 2.8% last week, April 11-17, compared to the week before. And that increase is largely explained by a spike in testing:There were 22% more coronavirus tests performed last week (an average of 51,271 a day) compared to the previous seven days (41,960 daily average).
