Health experts say the UK may be entering one of its most severe flu seasons in a decade. Early signs suggest this year’s outbreak could be worse than last winter, when nearly 8,000 people died, and worse than the season before, when flu contributed to 16,000 deaths.
A new flu variant has appeared earlier than normal and is spreading faster, raising concern among doctors and public health officials.

New Flu Strain Spreading Quickly

Researchers have identified a sudden change in the H3N2 flu strain, with seven new mutations detected this summer. Scientists say these changes appear to make the virus easier to catch and easier to pass on.
Professor Nicola Lewis from the World Influenza Centre told the BBC that this year’s pattern is “unusual” and “worrying,” though she urged people not to panic.

Rising Cases in the UK and Abroad

Flu cases began increasing in September and have continued to rise across the UK. Japan has already closed schools in response to large outbreaks.
Experts warn the number of infections may climb even faster as people spend more time indoors during the colder months.

Professor Christophe Fraser of the University of Oxford said the UK is “already well into” the flu season and that early indicators point to a “bad winter.”

NHS Urges People to Get Vaccinated

Health officials say the H3N2 subtype tends to be more severe and more disruptive than other strains. The UK Health Security Agency (UKHSA) is encouraging everyone eligible to book their flu jab as soon as possible.
This includes people over 65, pregnant women, children, and those with conditions such as asthma, diabetes, or heart disease.

How to Protect Yourself and Others

Doctors advise people with flu symptoms—such as fever, cough, or body aches—to limit contact with others and rest at home. Most people recover within one to two weeks, but symptoms can last longer.
If symptoms worsen or fail to improve after seven days, people should contact their GP.
