UK Hospitals Face Record Flu Cases Amid Doctors' Strikes, NHS Under 'High Alert'

Record Flu Admissions Strain English Hospitals

Hospitals across England are currently operating under 'high alert' as the number of patients admitted with influenza reached a record high of 3,140 by the end of last week, specifically the week ending December 14, 2025. This figure represents an 18% rise from the previous week and marks the highest total ever recorded for this period in the winter season. The unprecedented surge comes as the National Health Health Service (NHS) grapples with the additional strain of ongoing industrial action by resident doctors.

Flu Activity and Regional Variations

The current flu season has commenced earlier than usual, contributing to the significant pressure on healthcare services. While national flu activity appears to be stabilising, according to the UK Health Security Agency (UKHSA), it remains too early to definitively state whether the peak has been reached. Regional data reveals stark differences in the spread of the virus. Admissions saw substantial increases of 39% in the East of England and 40% in the South West. Conversely, the North West experienced a 4% decrease in hospital flu cases, a slowdown attributed by NHS officials partly to higher vaccination rates and increased public caution.

Impact of Industrial Action

The escalating flu crisis is compounded by a five-day strike by resident doctors in England, which commenced on December 17, 2025. Health and Social Care Secretary Wes Streeting stated that the strike action had 'undoubtedly added to the pressure' on hospitals this winter. Professor Meghana Pandit, NHS National Medical Director, acknowledged the challenging situation, noting that 'Combined with the impact of strikes, a stream of winter viruses means many hospitals will be on high alert in the days ahead.' The industrial action has led to concerns about significant disruption to patient appointments, with the NHS prioritising life-saving care.

Broader Winter Pressures on the NHS

The health system is facing widespread pressure, with average daily bed occupancy reaching 94.2% last week. Staff absences also saw a rise of over 1,100 in a single week. In addition to influenza, hospitals are also contending with an increase in other winter viruses, including norovirus, which saw 427 cases in hospitals daily last week. The NHS continues to urge eligible individuals to get their flu vaccination, with over 18 million people having already received a jab, and advises the public to practice good hygiene to help curb the spread of infections.
