Doctors warn London hospitals face a “triple threat” as Christmas and New Year gatherings bring a wave of admissions for flu and winter viruses.
NHS bosses urged patients to get vaccinated amid “extreme pressures” caused by infectious illnesses that forced them to close beds.
In the capital, the number of flu patients hospitalised stood at 419 in the week ending January 4, NHS London said.
It’s believed festive gatherings may have led to “bounce back” in winter viruses.
As of Sunday, 45 beds at St George’s Hospital in Tooting, Epsom in Surrey and St Helier University, Carshalton, were occupied by people needing specialist care.
Some beds have also had to be closed due to the influenza and other other illnesses such as norovirus.
In south-east England, flu patient numbers increased by 24 per cent (jumping from 290 to 360), while in the eastern region they rose 17 per cent (from 338 to 396).
Elaine Clancy, group chief nurse for the St George’s, Epsom and St Helier, warned of a triple threat from cold weather, winter bugs and sicker people.
She said: “It’s been a bleak start to the new year as, like other hospitals up and down the country, we’re seeing some very sick patients come to our hospitals – and the cold weather and winter illnesses are having a real impact.
“Don’t make the mistake of thinking flu is just a bad cold – these figures show the infection can make people seriously ill, and I’d urge people to take steps to ensure they and their loved ones don’t suffer.”
A spokeswoman said getting vaccinated, washing hands and staying home when displaying symptoms can all prevent the spread of respiratory viruses.
Londoners can also take steps to help themselves by keeping warmer by heating homes to at least 18C in key rooms and wrapping up when going outside.
Checking in on vulnerable friends, family and neighbours, and ensuring they have food, medication, and warm clothing is also recommended.
Health Secretary Wes Streeting said on Thursday: “While the NHS is better prepared and performing more strongly than this time last year thanks to the tireless work of staff, the current cold snap is putting fresh pressure on frontline services.
“Flu can be serious, particularly for older people, young children and those with underlying conditions, and vaccination remains the best protection. I urge everyone who is eligible to get their flu jab as soon as possible.
“By acting now, we can help keep people out of hospital, support our NHS staff through the toughest weeks of winter, and ensure emergency care is there for those who need it most.”
