The nation has repeatedly recorded more than 3,000 dead per day over the past few weeks.

“We are entering a very dangerous new phase of the pandemic, and we’re going to need decisive early national action to prevent a catastrophe in January and February,” said Andrew Hayward, professor of infectious disease epidemiology at University College London.

More than 71,000 people in Britain have died within 28 days of a positive test for the disease.

Federal Emergency Management Agency has received nearly 2,200 aid requests from hospitals and thus far has approved about 15% of them, for a total of $894 million, the agency told Reuters. Hospitals can request more money as U.S. infections surge, and FEMA officials expect total aid awards to rise significantly.

Some health policy experts say that large and well-capitalized nonprofit systems – which typically pay no taxes – do not need the additional relief money. Among the aid applicants are some of the nation’s best-known health systems, including the Cleveland Clinic, Providence and Stanford Health Care.
