858 infected across 101 new COVID-19 outbreaks at Michigan schools – MLive.com

There were 101 new COVID-19 outbreaks linked to schools last week, resulting in the infection of at least 858 students and staff, according to the state’s latest weekly report.

Michigan’s health departments were also tracking 319 ongoing school outbreaks from previous weeks, which have infected at least 3,017 residents. Ongoing outbreaks include clusters identified in previous weeks that had at least one additional case in the past 28 days.

In total, there were 420 active outbreaks affecting 3,875 students and staff as of Monday, Oct. 18.

Until recently, an outbreak was defined by the Michigan Department of Health and Human Services as two or more cases with a link by place and time indicating a shared exposure outside of a household. However, on Sept. 27 the MDHHS announced it would increase the minimum outbreak threshold to three people, “in order to promote consistent reporting among states.”

Schools continue to be the most common setting for reported COVID-19 outbreaks, and individuals 5 to 18 years old represent the largest increase in cases since Sept. 1. Part of that is because children younger than 12 aren’t eligible for a vaccine, and less than 50% of the eligible teens have gotten a shot.

Additionally, only 222 school districts have a mask policy, compared to 311 that have no mask policy. The CDC recommends a layer approach to prevention strategies, including promoting vaccinations, correctly wearing masks, allowing for physical distancing and promoting screening and testing for illness.

Outbreak data for K-12 schools includes only cases in which the student or staff was infected at school or at a school-related function. Those who caught the virus outside of school are not included.

The state includes this disclaimer with the data: “This information does not provide a complete picture of school-related outbreaks in Michigan and the absence of identified outbreaks in an educational institution in no way provides evidence that, in fact, that school is not experiencing an outbreak.”
