Killer Flu Warning for UK as Virus Mutates to Bypass Immunity
Experts have issued a warning about a potentially deadly flu strain that could severely impact the UK this winter. This year's seasonal flu may be worse than ever because the virus has mutated, enabling it to evade some immunity defenses established in our bodies.
Early Start to Flu Season
The flu season has begun a month earlier than usual, coinciding with an NHS "urgent SOS" alert due to rising flu cases.
Significant Virus Mutation
Influenza viruses constantly change, which is why a new flu vaccine is developed yearly. Typically, these changes are minor, but this summer the virus underwent a notable shift causing increased concern among experts.
Prof Nicola Lewis, World Influenza Centre, Francis Crick Institute, stated, "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."
H3N2 Strain Mutation Details
The H3N2 seasonal flu strain experienced seven mutations in June, significantly altering its behavior.
Flu Symptoms and Risks
- Symptoms range widely: some people fall ill for a few days, others show no symptoms at all.
- The virus poses high risks to older adults and vulnerable individuals with underlying health conditions.
Author's summary: This winter's flu could be unusually severe due to a significant virus mutation that helps it evade immunity, prompting early alerts and concerns for vulnerable populations.
