New Mutated Flu Strain Sparks Severe Illness Across the UK
A new variant of the flu virus has begun spreading earlier than usual in the UK and may cause thousands of deaths this year.
Public Health Concerns and Responses
- Experts warn the UK might face the worst flu season in a decade, surpassing last year's 8,000 deaths and the previous season's 16,000 deaths.
- Japan has closed schools as a precaution.
- The UK Health Security Agency (UKHSA) advises people to avoid contact if symptomatic.
- Doctors recommend seven days of isolation if someone becomes ill.
Characteristics of the New Strain
The new flu strain appears to be easier to catch and spread than typical seasonal flu, described as "hotter and nastier."
Professor Nicola Lewis, director of the World Influenza Centre at the Francis Crick Institute, told the BBC: "We haven't seen a virus like this for a while, these dynamics are unusual. It does concern me, absolutely. I'm not panicking, but I am worried."
Mutation Details and Expert Opinions
In June, a sudden mutation was detected in the H3N2 variant involving seven new mutations, potentially increasing its transmissibility.
Professor Derek Smith, director of the Centre for Pathogen Evolution at the University of Cambridge, said: "It almost certainly will sweep the world."
Flu cases began to rise sharply in the UK from September, supporting concerns that these mutations help the virus spread more easily.
