The government has outlined emergency legislation to tackle coronavirus, including measures to allow people to leave their jobs and volunteer to care for those affected.
Proposals would also allow court cases to be heard via video links.
It comes ahead of an expected move from the UK's "containment" phase of the outbreak response to "delay".
Meanwhile, Chancellor Rishi Sunak has pledged to address the outbreak in his first Budget on Wednesday.
The emergency coronavirus legislation could be introduced in the House of Commons this month, BBC political correspondent Chris Mason said.
By Saturday, the number of confirmed cases in the UK had risen to 209 from 164 the day before, and two people have died after contracting the virus - the latest being an 83-year-old man at Milton Keynes Hospital.
Volunteers would need training and protective equipment, but Dr Dolphin said retirees brought back into service would be aware of the risks they were taking in tackling a virus that disproportionately affected older people.
"Being exposed to infectious disease is part of being a doctor or a nurse," he said.
