The US has recorded more than 250,000 deaths from Covid-19, a bleak marker as cases soar once again across the country.
According to Johns Hopkins University, the country has now reported 250,029 deaths and nearly 11.5 million cases.
It has more reported infections and a higher death toll than any other country worldwide.
And cases have once again started to soar throughout the US, hitting new daily highs in the last week.
Speaking to the BBC on Wednesday, top US infectious diseases Dr Anthony Fauci said the country was "going in the wrong direction at a very precarious time", with people more likely to gather inside as the weather gets colder.
New York City – the epicentre of the US outbreak in the spring – has ordered the closure of its schools from Thursday, amid a spike in cases.
The decision to close the US's largest public school system came as positive test rates for the virus surpassed the 3% threshold, officials say. It will affect some 300,000 children.
What did Dr Fauci say?
In an interview on the BBC News channel, Dr Fauci warned about the new surge in cases leading to more deaths.
"It's a very serious situation because there are lagging indicators," he said. "So when you see the massive increase in cases as we're seeing now particularly as more and more people are doing things inside, we're in a very difficult situation."
