Health services across the United Kingdom are facing significant strain as a new and distinctive flu variant drives a sharp rise in hospital admissions at the start of 2026.
Surge in Hospital Admissions and Critical Incidents
Data shows a worrying increase in flu-related hospitalisations, with an average of 2,924 people admitted daily with the virus up to January 4. This marked a 9% rise compared to the previous week. The pressure on the NHS has become so severe that four hospital trusts have declared critical incidents.
Three trusts in Surrey and one in Kent made the declaration due to what they describe as "significant and sustained pressures" on their services. Furthermore, major trusts including University Hospitals of North Midlands NHS Trust, University Hospitals Birmingham NHS Foundation Trust, and Betsi Cadwaladr University Health Board in North Wales all reported exceptionally high demand on Thursday.
The 'Distinctive' Symptoms of the New Strain
Medical professionals are highlighting that the emerging virus, identified as subclade K of the A(H3N2) subtype, is presenting with a set of pronounced symptoms. Respiratory specialist Dr Juanita Mora outlined the key signs, which include:
- Persistently high fevers that can last five to seven days.
- A severe, phlegmy cough that does not easily subside.
- Gastrointestinal issues such as vomiting and diarrhoea.
- Significant joint and muscle aches.
Dr Mark Loafman noted that the fever associated with this year's flu is more intense than usual and is proving difficult to manage, with standard treatments like paracetamol or ibuprofen often failing to bring it down effectively.
Public Health Advice and Urgent Calls for Vaccination
In response to the outbreak, Health Secretary Wes Streeting has issued a strong plea for eligible individuals to get vaccinated. "Flu can be serious, particularly for older people, young children and those with underlying conditions, and vaccination remains the best protection," he stated. "I urge everyone who is eligible to get their flu jab as soon as possible."
The NHS lists the main symptoms of flu, which typically come on suddenly. They are:
- A sudden high temperature (38C or above).
- An aching body.
- Feeling exhausted.
- A dry cough and sore throat.
- Headache, difficulty sleeping, and loss of appetite.
- Nausea, vomiting, or diarrhoea (more common in children).
For those with symptoms, the health service recommends rest, staying warm and hydrated, and using remedies like hot honey and lemon. Paracetamol or ibuprofen can help with fever and pain. Anyone over 65, pregnant, or with a long-term health condition should contact NHS 111 or their GP, especially if symptoms persist for more than seven days.
