NHS leaders caution that soaring flu cases could mark one of the toughest winter periods in recent years
BY FRANCESCA RAPISARDA
Hospitals across the UK have been reporting a sharp increase in flu-related admissions, prompting warnings from health leaders that services are entering one of the most difficult winter periods in recent years.
New NHS data released this week showed a steep rise in patients needing hospital care for influenza, with numbers climbing significantly faster than expected for December. Health officials said the spike is being driven by an aggressive strain of the virus and unusually early community transmission.
NHS England said the current volume of flu patients is placing intense pressure on already stretched services, with senior clinicians warning that the system is approaching a critical point. Several regions have reported sustained increases in admissions over the past 10 days, with no clear indication that cases are yet reaching a peak.

Trust leaders across England have described emergency departments as “exceptionally busy”, noting that the combination of flu, other seasonal infections, and high bed occupancy is making it increasingly difficult to maintain normal winter capacity.
In London, NHS medical director Dr Chris Streather said to the BBC that staff were working under “significant operational pressure”, urging the public to take symptoms seriously and seek vaccinations where eligible. He cautioned that although the situation is challenging, comparisons with the early pandemic should be avoided. “Rates are rising quickly, but we must stay measured in how we describe this,” he said.
Healthcare teams in Scotland, Wales and Northern Ireland are reporting similar trends, with flu circulating widely among children and young people. In several local areas, schools have reintroduced infection-control measures to limit further spread after witnessing notable spikes in absence.
Public health officials say the groups most affected by severe symptoms remain adults over 75 and children under five, both of whom are experiencing the highest hospitalisation rates so far this season. Experts believe a combination of limited recent exposure to circulating flu strains and ongoing pressures in primary care may be contributing to higher susceptibility.
There are also concerns about rising cases of norovirus, which NHS England says is beginning to occupy an increasing number of hospital beds alongside flu patients.
Health Secretary Wes Streeting has described the emerging winter picture as “extremely serious”, urging eligible groups to receive flu vaccinations before Christmas. More than 17 million people have already been vaccinated, but uptake remains uneven across some communities.
Streeting warned the BBC that flu admissions could continue rising into January, potentially tripling if current patterns persist. “We are facing a winter challenge that demands everyone’s cooperation,” he said, noting that service disruption could worsen if planned industrial action by resident doctors goes ahead later this month.
The UK Health Security Agency (UKHSA) said infection rates in the community are continuing to rise, though the most recent figures show a slightly slower week-on-week increase. Epidemiologists caution that this should not be interpreted as a turning point.
