The next few weeks will be "nail-bitingly difficult" for the NHS, hospital bosses have warned.
Staff absences and the new Covid variant are creating a "challenging situation", Saffron Cordery, of NHS Providers, which represents hospital trusts in England, said.
Doctors are urging the public to "take it seriously and follow the rules" to protect the health service.
On Thursday, the UK reported 55,892 daily Covid cases, the highest to date.
Meanwhile, new analysis by Imperial College London has confirmed the new variant of coronavirus has a much quicker rate of transmission than the original strain.
And an analysis of NHS England data from 23 hospital trusts by the Health Service Journal shows that Covid-19 is putting intense pressure on adult acute care and general beds, as well as those in intensive care.
It found that more than a third of these beds were occupied by patients with Covid-19 on Tuesday, and in three trusts - North Middlesex in London, and Medway and Dartford and Gravesham in Kent - the figure was more than half.
Based on the recent rise in numbers, the analysis suggests that all acute and general beds might soon be filled with Covid-19 patients.
Speaking on BBC One's Breakfast, Ms Cordery said the surging transmission and death rates were "incredibly hard to deal with".
"When we are seeing major London trusts saying they are under pressure, that's when we know we're in a very challenging space," she said.
A leading intensive care doctor has urged people to follow restrictions until the vaccination programme is fully rolled out.
Prof Anthony Gordon, of Imperial College, told BBC Radio 4's Today programme: "There is light at the end of the tunnel so I would urge people to hold on for these few more months while the vaccination programme makes that difference and then we can truly get back to normal.
"But we can't overrun the health service because this will just lead to thousands more deaths."
More than three-quarters of England is currently under the strictest tier four - "stay at home" - coronavirus measures, and other parts of the country have joined higher tiers.
Mainland Scotland, Northern Ireland and Wales are under lockdown.
