"Folks here's the truth: the pandemic is still here. It's going to be here for the foreseeable future until we get it under control or until we have safe and proven widely-available vaccine," Biden, who was campaigning in the battleground state of Pennsylvania, said. "COVID-19 is a fact of nature."
He went on to say that the 'greatest indictment' of Donald Trump was his 'complete, compelling lack of leadership' in the handling of the pandemic.
Trump is eager to reopen the economy and resume political campaigning even as coronavirus cases have started to rise again, with record increases reported this week in Oklahoma, Texas and Oregon.
Nationally, Biden now has his widest lead over Trump in the race, according to a Reuters/Ipsos poll on Wednesday, showing the Democrat with a 13-percentage-point lead.
