Michigan COVID data Dec. 15, 2021 (WDIV)

DETROIT – Michigan reported 11,722 new cases of COVID-19 and 330 virus-related deaths Wednesday -- an average of 5,861 cases over the past two days.

Wednesday’s update brings the total number of confirmed COVID cases in Michigan to 1,408,189, including 25,570 deaths. These numbers are up from 1,396,467 cases and 25,240 deaths, as of Monday.

The deaths announced Wednesday include 230 identified during a Vital Records review.

Testing has increased to around 50,000 diagnostic tests reported per day on average, with the 7-day positive rate at 17.07% as of Monday -- a decrease from last week. Hospitalizations have been steadily increasing for several weeks and are at the highest point of the pandemic.

The state’s 7-day moving average for daily cases was 5,664 on Wednesday. The 7-day death average was 113 on Wednesday. The state’s fatality rate is 1.8%. The state also reports “active cases,” which were listed at 238,400 on Wednesday.

Michigan has reported more than 10.8 million doses of the COVID-19 vaccine administered as of Monday, with 67.7% of 16+ residents having received at least one dose, while 62.2% of 16+ residents are considered fully vaccinated.

Across Michigan’s entire population, 62.4% have received at last one COVID vaccine dose.

According to Johns Hopkins University, more than 49 million cases have been reported in the U.S., with more than 796,700 deaths reported from the virus. Globally, more than 8 billion vaccine doses have been administered, including more than 478 million doses in the U.S. alone.

Worldwide, more than 269 million people have been confirmed infected and more than 5.2 million have died, according to Johns Hopkins University. The true numbers are certainly much higher, because of limited testing, different ways nations count the dead and deliberate under-reporting by some governments.

Data shows Michigan schools without mask mandates saw 62% more coronavirus spread

As the number of COVID cases continue to surge in Michigan, new data reveals that mask mandates in school appear to be working to slow the spread of the virus.

It is one of the most, if not the most, divisive issue inside the pandemic -- mask mandates, especially in schools. Anger and frustrations has boiled over inside, outside and at board meetings. But new data is supporting the use of masks in schools.

Flu expected to circulate more this year due to fewer COVID precautions

While coronavirus pandemic precautions helped keep the flu away last year, experts are worried that we won’t be so lucky this year.

Precautions and restrictions designed to prevent the spread of COVID-19 actually also helped prevent the spread of the flu, a respiratory illness caused by influenza viruses, during the 2020 flu season. This time last year, health experts were concerned that the U.S. would experience a “twindemic” with COVID and the flu, but that didn’t happen, likely due to a combination of mask wearing, social distancing, most schools being closed and overall reduced travel.

But this year, many of those precautions and restrictions are no longer in effect, and the flu is expected to circulate more widely.

CDC recommends vaccinated people wear masks in schools, some indoor settings

The Centers for Disease Control and Prevention (CDC) is now recommending that even vaccinated people wear masks indoors in parts of the United States where coronavirus is surging.

The CDC on Tuesday, July 27 cited new information about the ability of the delta variant to spread among vaccinated people. The CDC also recommended indoor masks for all teachers, staff, students and visitors to schools regardless of vaccination status.
