The governor of Wisconsin has called on Donald Trump to consider canceling a pair of campaign rallies scheduled for Saturday as the key swing state struggles to control a 22% surge in coronavirus cases over the last week.The increasing infections in Wisconsin are part of a national trend of rising cases playing out as the presidential election enters the homestretch and the president, trailing badly in the polls, accelerates his search for votes.That search will take Trump to airport hangars in the Wisconsin cities of Green Bay and La Crosse on Saturday, where thousands of people, many unlikely to be wearing masks based on recent rallies, are expected to huddle in open-air crowds to hear Trump speak. Barring a surprise victory elsewhere, Trump needs to win Wisconsin to win re-election.The campaign plan took shape as a major new study by researchers at Cornell University suggested that Trump is the world’s largest source of misinformation about Covid-19. The findings were based on a comprehensive survey of 38m articles from traditional and online media.While incidents of coronavirus transmission in open-air environments have not been documented as thoroughly as viral spreading in indoor settings, Wisconsin’s governor, Tony Evers, a Democrat, suggested it was reckless for the president to draw thousands of people together in a “red zone” for transmission.“The president could do two things: one is maybe not come to these two municipalities and cities that are ranked right up towards the top of all the places in the country [for infections],” Evers said.“The second thing that could be done is for him to insist that if people are there, they wear a mask. He can make that happen. He could wear one too. Those are the two things that he could do to make sure that it doesn’t become a super-spreader event.”New daily infections have risen in 25 states in the past week, according to analysis by Axios published on Thursday, with about 43,000 new cases a day on about 935,000 daily tests in the United States.And the city of Boston hit the brakes on reopening on Wednesday after the state public health department said the city could be a “red zone” for active circulation of the virus. Infection rates were above 7% in some neighborhoods, Marty Walsh, the mayor, said at a news conference, and half the recent cases have been among people under age 29.Walsh urged people not to hold house parties tied to a weekend football game and told the city’s large student population to observe social distancing guidelines.“You wanted to come to college in Boston, you wanted to be treated like adults. Well then, act like it,” Walsh said. “We’re asking you to be responsible.”Republican officials in some states have followed Trump’s lead in relaxing or ignoring coronavirus mitigation measures even as cases rise nationally. Governor Tate Reeves of Mississippi, where new case numbers are flat, allowed a statewide mask mandate to expire on Wednesday.“There is a difference between being wise and being a government mandate,” Reeves said. “We have to trust the people of this country to look after themselves and to make wise decisions.”The Republican governor of Missouri, Mike Parson, who is running for re-election, defended himself this week over reports that an outbreak of dozens of cases at a military veterans home in Missouri followed his campaign visit there.Parson and his wife later tested positive for Covid-19. A spokesperson for the candidate told the local Riverfront Times “there is no connection between the two”.Trump also denies that his campaign events have spread the virus.“So far, we’ve had no problem whatsoever,” he said during the presidential debate on Tuesday night. “It’s outside. That’s a big difference, according to experts. We do them outside. We have tremendous crowds as you see.”But Trump does not always “do them outside”. Local health officials tied a Trump rally in Tulsa, Oklahoma, that drew more than 6,000 people into an arena in July to an outbreak of hundreds of cases in the area. Trump supporter Herman Cain, the businessman and former presidential candidate, died of Covid-19 after attending the event. More
