In their first televised debate, Democratic challenger Joe Biden accused US President Donald Trump of concealing the danger posed by the coronavirus and of having no plan to combat it, while the White House incumbent hailed his administration's response.
"The president has no plan. He has not laid out anything. He knew all the way back in February how serious this crisis was. He knew it was a deadly disease. What did he do? He's on tape acknowledging he knew it, he said he didn't tell us or give people a warning of it, because he didn't want to panic the American people," the former vice president said.
Trump countered that his administration had "done a great job" in responding to the virus, saying: "We got the gowns, we got the masks, we made the ventilators… and now we're weeks away from a vaccine, we're doing therapeutics already."
Trump's response to the virus -- which has killed more than 205,000 people in America and infected nearly 7.2 million -- is a key issue for voters who will decide whether the real estate mogul-turned-politician will win a second term.

Trump downplayed the danger of the virus
Trump told Bob Woodward on February 7, 2020 that the virus is "deadly stuff" and is "more deadly than... even your strenuous flus," according to a recording of a call between the investigative journalist and the US president.
"You just breathe the air -- that's how it's passed," Trump said.
Although Trump knew the virus was dangerous, he did not reflect that in his public remarks, instead repeatedly downplaying the risks it posed.
On February 27, Trump had said the risk the virus posed to the American people was "very low" and that the number of cases "is going to be down to close to zero" within days, during one of his daily briefings on the virus. He then compared it to the common flu on March 9.
Trump told Woodward on March 19 that "I wanted to always play it down," adding: "I still like playing it down, because I don't want to create a panic."
Trump's virus response
There have been major shortages of key personal protective equipment such as masks during the coronavirus crisis, which Trump's administration has taken steps to combat.
But while the president has invoked the Defense Production Act to respond to the pandemic, the non-partisan Congressional Research Service said in late July that, "Despite continued congressional concerns over personal protective equipment (PPE) availability, the Administration has not consistently employed DPA authorities to expedite PPE contracts."
Coronavirus vaccines are, as Trump said, in the works, but his timetable of "weeks" is questionable.
Dr Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases (NIAID) and a member of the Coronavirus Task Force, said that: "We hope as we go along that by the end of this year, or the beginning of 2021, we will at least have an answer whether the vaccine, or vaccines plural, are safe and effective."
Trump has also advocated treatments that were ineffective if not potentially harmful, and delayed advocating the use of face masks, despite evidence that they help curb the virus's spread.
Trump repeatedly pushed hydroxychloroquine as a treatment for Covid-19. But according to health authorities and independent experts, the drug -- which Trump said he took himself -- does not treat or prevent the disease caused by the novel coronavirus, and can in fact pose health risks.
He also suggested countering the virus with "light inside the body" or injecting disinfectant.
Although the US Centers for Disease Control and Prevention recommended on April 3 that Americans wear face masks to help curb the spread of the virus, Trump refused to do so in public until July, a stance that was embraced by his political supporters.
The president did not take a firm stance in support of masks until later that month, as cases rose in southern states.
Trump said in late March that keeping the virus death toll in the 100-200,000 range would mean that "we all, together, have done a very good job." Those figures have been exceeded.
Biden's coronavirus plan
Biden's coronavirus plan calls for steps including making free testing widely available -- something that has been done under Trump, albeit with major delays in getting results in some areas -- accelerating the development of treatments and vaccines, which is currently taking place, and eliminating out-of-pocket costs for Covid-19 treatment, which has currently only been done for testing.
