Health experts are warning of a severe strain of influenza that could sweep through the UK this winter. The seasonal flu virus has mutated, potentially evading some immunity defenses. This year’s flu season started a month earlier than usual, prompting an urgent alert from the NHS as flu cases surge.
Each year, a new flu vaccine is developed to combat the evolving strain of the influenza virus. However, experts are concerned about the significant mutations observed in this year’s virus. The H3N2 flu strain has undergone unusual dynamics with seven mutations occurring in June, raising alarm among experts.
Flu symptoms vary, with some individuals experiencing mild illness while others remain asymptomatic. Nevertheless, the flu can be life-threatening, especially for the elderly and those with underlying health conditions. The return of children to school post-half term, coupled with the onset of colder weather, has led to a notable increase in flu cases in the UK.
Experts emphasize the severity of the current H3N2 influenza strain, noting its potential impact on vulnerable populations. Hospital admissions for flu in England have risen significantly earlier this year compared to previous seasons, indicating a potentially challenging flu season ahead.
Health authorities are urging the public to get vaccinated against the flu to mitigate the potential impact of the mutated virus. The flu vaccine is designed to offer protection against different flu virus types, including drifted strains. Vaccination remains a crucial defense measure, particularly for high-risk individuals, to prevent severe illness and hospitalization during the flu season.
