The head of an intensive care unit (ICU) at a hospital in the US state of Florida has told the BBC that the facility is struggling with the number of patients being admitted.

"We have gone from one Covid floor to two, to three, and now we have a fourth area," Dr Andrew Pastewski, ICU Medical Director at Jackson South Medical Center in Miami, told the BBC's Newshour programme.

"At some point you're going to need some kind of Covid nursing home for patients who aren't that sick but can't go back to their skilled nursing home," he added.

Dr Pastewski also told Reuters news agency that the coronavirus "destroys the strength" of his elderly patients.

"If it's an elderly person that gets intubated, you know that it's the end because we have not been able to get elderly people off the ventilator."
