The contest between Donald Trump and Joe Biden comes to a head on Tuesday.
Twenty-one states are experiencing outbreaks, with some of the most severe in the states that will be key in deciding the 2020 election.In the battleground state of Wisconsin, hospitals in Green Bay warned that President Trump’s Friday rally there could make the outbreak worse.
“It is more important now than ever to avoid large crowds, especially here in Green Bay, Wisconsin, where we are seeing some of the most rapid spread of Covid-19 in the United States,” a joint statement from several hospitals said.On Friday, ahead of his scheduled rallies, Mr Trump tweeted: “More Testing equals more Cases. We have best testing. Deaths WAY DOWN.”
At recent Trump rallies, attendees have been screened and given masks. The events have also been held outdoors due to the pandemic. But there has not been social distancing, and some supporters continue to avoid masks.
Mr Biden has also continued to campaign, though the Democrat’s rallies have enforced social distancing practices, opting to have people attend inside their cars, for example.
