Wisconsin and other states in the U.S. Midwest and beyond are battling surges in Covid-19 cases, with new infections and hospitalizations rising to record levels in an ominous sign of a nationwide resurgence as temperatures get colder.

U.S. cases of the novel coronavirus crossed 8 million, rising by 1 million in less than a month, as another surge in cases hits the nation at the onset of cooler weather.

The number of new Covid-19 cases rose 11% in the United States last week compared to the previous seven days, with infections spreading rapidly in the Midwest, which reported some of the highest positive test rates, according to a Reuters analysis.

Covid-19 shattered records for new cases in the U.S. Midwest, straining hospitals, and will darken New York’s Broadway theaters until June, a decision the Actors’ Equity Association union called “difficult but responsible.”

Six states reported record numbers of hospitalized Covid-19 patients, including Wisconsin, where officials issued a new order limiting the size of indoor public gatherings.

Nine U.S. states reported record increases in Covid-19 cases over the last seven days, mostly in the upper Midwest and West where chilly weather is forcing more activities indoors.

New cases of Covid-19 rose in 27 out of 50 U.S. states in September compared with August, led by an increase of 111% in Wisconsin, according to a Reuters analysis.
