The head of NHS England, Sir Simon Stevens, has revealed he contracted coronavirus and self-isolated at home for seven days.
He has said his condition was at "the milder end of the symptoms".
Sir Simon has appealed to people not to stay away from urgent NHS care, BBC reports.
New figures for England and Wales show an unexplained number of non-coronavirus deaths, some of which may be due to people avoiding hospitals because of coronavirus risks.
Sir Simon said: "These figures underline the seriousness of coronavirus - there are 19,000 coronavirus patients in hospitals in England.
"But we've also got capacity in the NHS to look after patients with urgent and emergency needs that aren't about coronavirus so our message is... our staff are here to look after you."
