The number of reported infections in the US has now surpassed 2.5 million. Over 125,000 Covid-19 patients are confirmed to have died nationwide – more than in any other country. A surge in cases is particularly acute in several southern and western states. One of those is Arizona where twice as many people are being admitted to hospital with Covid-19 symptoms now, compared to the start of the month. And that’s putting a huge strain on medical resources and the staff.

Bradley Dreifuss is an ER doctor in Tucson and he’s been talking about the pressures he and his colleagues are under.

Brad appeared again on the BBC in November for a follow-up interview.
