Rising numbers of COVID-19 cases and outbreaks in Minnesota schools are narrowing the list of counties where the virus is spreading at low enough rates to allow for full, in-person instruction.
Statewide, more than 500 schools had at least one positive case in the last two weeks, and 24 public and private schools reported outbreaks with at least five positive cases, according to Minnesota Department of Health data released Thursday. But health officials, facing increasing challenges from parents, students and community members trying to conceal the spread of the virus to keep schools open and sports programs running, say those numbers are almost certainly an undercount.
Susan Klammer, an epidemiologist with the department, said in some communities, resistance to testing or quarantining after COVID-19 exposure has become more pronounced — and, in some cases, hostile — in the period since the Minnesota State High School League restarted school sports programs. Klammer said police have been called in cases where health workers were threatened for recommending that students quarantine, and students were threatened and harassed by their peers after seeking COVID-19 testing. Health officials have been notified of schools where groups of students have made pacts not to get tested, and to keep quiet if they think they are sick or have been exposed to the virus.
"It is incredible how the tenor has changed in the last couple of weeks," Klammer said.
The shift comes as the state is experiencing an uptick in COVID-19 cases and deaths. On Thursday, the Department of Health reported an additional 19 deaths and 1,169 positive cases. The death tally was the second-highest since mid-June, and brought the state's total count to 2,199 deaths.
Since Oct. 8, Minnesota has reported more than 1,000 new cases each day, bringing the total number of known infections to 117,106. Although some of that is the result of more testing, new case growth on Thursday slightly surpassed the growth in tests. Young adults represent the largest share of new cases, and public health officials are concerned that group will pass on the virus to people who are the most vulnerable to complications.
The spread of the virus across communities of all sizes has contributed to the growing number of school-related cases.
Since Aug. 1, the state has tracked 1,803 cases in which the person who tested positive spent time in a school building when they could have infected others. Students make up slightly more than half of that group, with teachers and school staff accounting for the remainder.
