(BBC) The US saw a record high of 91,000 new Covid-19 cases reported on Thursday, with spikes in dozens of states just days before the presidential election.
The same day, over 1,000 Americans died with the virus, as the national death toll and number of patients in hospital continue to trend upward.
The US is just shy of nine million total cases, according to a Johns Hopkins University tally.
The contest between Donald Trump and Joe Biden comes to a head on Tuesday.
This is the third time this month that the US daily death toll has surpassed 1,000, according to Reuters.
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.
Mr Trump’s eldest son, Donald Trump Jr, made an appearance on Fox News on Thursday where he repeated his father’s line that the pandemic is under control.
“I went through the [Centers for Disease Control] data, because I kept hearing about new infections,” the younger Mr Trump said.
“But I was like, ‘Well, why aren’t they talking about deaths?’ Oh, because the number is almost nothing. Because we’ve gotten control of this and we understand how it works.”
CDC data on 29 October reported an additional 1,060 deaths due to Covid-19. The total US death toll is over 228,000 people.
US health experts are warning the case load and death toll will continue to rise as the flu season coincides with the outbreaks.
Infectious disease expert and White House coronavirus task force member Dr. Anthony Fauci told CNBC on Wednesday that the nation was “going in the wrong direction”.
“If things do not change, if they continue on the course we’re on, there’s going to be a whole lot of pain in this country with regard to additional cases and hospitalisations and deaths.”
