The NHS remains connected precocious alert complete flu, wellness bosses say, but location are clear signs nan surge successful nan microorganism has travel to an extremity for now astatine least.
Community dispersed appears to person stabilised, nan UK Health Security Agency says.
Meanwhile, nan emergence successful infirmary cases has slowed. And pinch conscionable complete 3,000 patients successful infirmary successful England pinch nan virus, nan dire prediction by NHS main executive Sir Jim Mackay of "between 5,000 and 8,000" cases has not materialised.
How superior past is this flu play truthful far, and really does it really comparison to erstwhile outbreaks of nan virus?


The awesome quality betwixt nan 2025 flu play and nan past 3 years is that nan microorganism started spreading a fewer weeks earlier than normal.
When personification goes to their GP aliases infirmary pinch flu-like symptoms, they tin beryllium swabbed and tested for influenza, Covid, RSV and different viruses.
UKHSA past records nan percent of those tests that travel backmost affirmative for flu.
Figures had been rising quickly complete nan autumn and astatine nan commencement of winter.
But past week nan dispersed of nan microorganism appears to person stabilised astatine a mean level, UKHSA says.
It is excessively early to opportunity whether this marks nan commencement of nan peak. Flu is unpredictable, a lull tin beryllium followed by different surge.


The image crossed nan 4 nations of nan UK is similar.
Some virologists person linked nan earlier flu play this twelvemonth to nan type of microorganism that is circulating - known arsenic H3N2.
Historically, seasons dominated by that strain thin to beryllium much severe, pinch larger numbers of hospitalisations successful older people, successful particular.
H3N2 has not been nan main shape of flu detected successful nan UK for 3 years, which whitethorn mean that little immunity has been built up successful nan population.
Scientists besides spotted a further displacement successful nan familial constitution of nan microorganism complete nan summer.
This seems to person fixed nan microorganism a head-start successful nan autumn.
Can we telephone it super-flu?
The sanction 'super-flu' has been utilized by nan NHS to picture this latest outbreak.
But that is not a aesculapian term, and it does not mean nan microorganism itself has abruptly go much vulnerable aliases harder to treat.
"It is misleading and a spot frightening to telephone it ace flu; it's conscionable a flu version that is intelligibly a small spot much infectious than normal," says Prof Lawrence Young, professor of molecular oncology astatine nan University of Warwick.
"What we're seeing is simply a flu play that's possibly 2 to 3 weeks earlier than normal."
Separately, nan NHS besides records nan number of nan sickest patients successful infirmary pinch flu complete nan winter. Trends successful infirmary information tends to lag down organization dispersed arsenic it takes immoderate clip for group to get sick capable to activity infirmary care.
Figures for past week showed nan number deed 3,140, an 18% emergence connected nan week before. But that was aft a 55% jump successful nan week earlier that.
Although nan nationalist fig masks what is happening crossed different regions pinch immoderate areas seeing numbers autumn and others still seeing steep rises.
Those complete 85-years-old are 5 times much apt to beryllium hospitalised than nan wide population.
Comparing outbreaks complete nan decades is difficult because testing has improved successful caller years, truthful a emergence successful infirmary admissions complete clip mightiness besides bespeak amended detection.
But estimated figures connected flu deaths shows that immoderate winters person been peculiarly superior complete nan past 20 years.
In 2017-18, for example, it's thought 25,000 group died from nan microorganism successful England, pinch attraction homes and older adults astir affected.
That twelvemonth an different shape of nan influenza B microorganism started circulating and nan 'beast from nan east' acold threat bought freezing temperatures to nan UK, creating nan perfect situation for nan illness to spread.
Just 3 years earlier that, successful 2014-15, modelling by scientists astatine UKHSA estimated that 35,000 had died, making it 1 of nan astir lethal flu seasons successful decades.
Again, that was blamed connected an outbreak of nan H3N2 shape of nan microorganism and a seasonal vaccine that was not good matched to nan nonstop shape of nan illness circulating.
There is thing successful nan information truthful acold which suggests thing comparable successful 2025, but we won't cognize for judge until nan first estimates for this season's influenza deaths are published successful nan caller year.
The connection coming from doctors and nan NHS is for millions of group to proceed to travel guardant for a flu vaccine.
Even though nan familial make-up of nan microorganism has shifted, nan main jab is still thought to connection an effective level of protection, peculiarly against ending up successful infirmary pinch terrible disease.
The flu vaccine is free connected nan NHS for those complete 65-years-old, young children, pregnant women, those pinch definite wellness conditions, carers, and front-line wellness and societal attraction workers.
All different adults tin get nan aforesaid vaccine for betwixt £15 and £25 from precocious thoroughfare pharmacists.
The latest information shows that much than 70% of older group and attraction location residents had taken up nan connection of a free jab by 14 December.
But vaccination rates successful immoderate different groups are overmuch lower.
Only 39% of each front-line NHS workers successful England person been vaccinated truthful acold this year.
