ST. PAUL — School-age children continue to be at the center of Minnesota’s latest wave of coronavirus infections with more than 4,000 between the ages of five and 19 testing positive for COVID-19 in the last week.

There are now 96 school buildings with outbreaks confirmed by the Minnesota Department of Health Thursday, Sept. 23, up from 26 buildings a week ago.

Cases in long-term care are also on the rise with 284 facilities reporting infections, up from 267 the week before. Infections in long-term care had fallen to fewer than two dozen in late June.

State health officials say nearly all new cases are driven by the more contagious delta variant, which can also cause more severe disease. Nearly all severe infections are in Minnesotans who are unvaccinated.

While breakthrough cases are on the rise, of the 3.1 million Minnesotans who are fully vaccinated 99% have not reported a breakthrough infection. There have been 23,330 breakthrough cases, 1,268 hospitalizations and 118 deaths in fully vaccinated residents.
