UK braces for winter flu surge amid NHS concerns
The UK is experiencing an early and severe flu season, often called 'super flu,' caused by the influenza A/H3N2 subtype, but this is within normal seasonal variations. The NHS is under pressure, especially in England's north and Midlands, with higher infection rates among children and vulnerable older adults. Vaccination remains the best protection, with effectiveness varying by age and vaccine type, and it is still advisable to get vaccinated even late in the season. People should stay home if sick and seek NHS guidance if symptoms worsen.
