ONE in four adults of working age in England are struggling with the flu as part of a "tidal wave" of infections, according to new data.
The latest surveillance data from the UK Health Security Agency (UKHSA) showed one in four tests done on Brits of all ages with coughs and colds tested positive for flu.
The tests were carried out last week and show cases have more than doubled from the previous week, when one in 10 cases tested positive.
There was a 70 per cent surge in hospital cases of flu in England in just seven days, the NHS said.
Health chiefs are now pleading with eligible Brits to get vaccinated immediately to avoid “festive flu" before it is "too late".
Last week, an average of 1,861 flu patients were in hospital every day, up from 1,099 the previous week - 3.5 times higher than the same time last year.
Medics fear hospitals will struggle to cope with surges of flu alongside Covid, cold virus RSV and the nasty vomiting bug norovirus, all hitting this winter.
Cases of norovirus were up ten per cent on the previous week and 64 per cent on last year.
While 152 children were in hospital with RSV each day - up 42 per cent from this time in 2023.
Health experts warn that this "quad-demic" is stretching NHS resources to its limit.
The risk of catching all four illnesses at once rises sharply at this time of year as people spend more time indoors with friends and family.
Eligible people are being urged to get jabbed.
The NHS provides vaccinations against flu, Covid and RSV.
Over-65s, pregnant women, and people with certain health conditions are among those who can get a free vaccination at a pharmacy.
Jabs are also being dished out at Christmas markets, football clubs, and supermarkets, to make them more accessible.
RSV vaccines are recommended during pregnancy and for adults aged 75 to 79.
There’s currently no vaccine to prevent norovirus, but research trials are underway to develop one.
Professor Sir Stephen Powis, boss of NHS England, said: "The tidal wave of flu cases and other seasonal viruses hitting hospitals is really concerning for patients and for the NHS - the figures are adding to our 'quad-demic' worries."
He added: "With one week left to book your vaccine, I cannot stress enough the importance of getting booked in to protect yourself against serious illness and to avoid 'festive flu.'"
Health and Social Care Secretary Wes Streeting, said: "With A&Es facing record demand, we are continuing to encourage people to protect themselves, their family, and the NHS by getting vaccinated before it’s too late.”
