NHS prepares for unprecedented flu cases is the same strain spreading across continental Europe
The flu season is off to an early start in the northern hemisphere, typically from mid-November to mid-February. However, it can begin as early as October and extend into May. In England, flu activity hit 11% in early November, up from 3% the previous year, indicating a significant escalation. This season seems to have begun four to five weeks earlier than anticipated.
NHS Prepares for Unprecedented Flu Cases
Current Outbreak and Strains
This flu season is primarily driven by the H3N2 strain of influenza A, which has adapted through several mutations. The predominant variant, known as subclade K, has been linked to Australia’s record-breaking flu season. Though it spreads rapidly, current evidence suggests that it does not result in more severe illness compared to earlier forms.
Flu Activity Across Europe
- Germany: The flu season began 2-3 weeks early, with notable circulation of H1N1 and H3N2.
- France: Flu cases increased significantly, with both H1N1 and H3N2 being reported.
- Spain: Infections have surpassed last winter’s peak, resulting in doubled hospitalizations.
- Ireland: Nearly 3,000 cases were recorded in the first week of December, reflecting a 49% increase week-over-week.
Regions differ in their flu experiences; some parts of continental Europe have just begun to see an increase in H3N2 cases. France’s public health agency noted a strong increase in flu activity among all demographics, with all regions except Corsica in the epidemic phase.
Vaccine Effectiveness
Due to the genetic changes in this year’s H3N2 strain, vaccines have shown reduced effectiveness against infections. According to the UK’s Health Security Agency, the vaccine provides approximately 70-75% protection for children against hospitalization, and 30-40% for adults. Despite the reduced efficacy, officials urge the public to get vaccinated to mitigate the risk of severe illness.
In France, over eight million people have received the flu vaccine, marking a 21% increase compared to last year. Among patients in intensive care, 58% were aged 65 and older, and a staggering 90% had pre-existing medical conditions. Notably, 98% of the vaccinated individuals in these cases had not received this year’s flu shot.
In Ireland, a concerning 73% of hospitalized flu patients had not received the vaccine, underscoring the ongoing challenges in combating this year’s influenza. As health organizations brace for unprecedented flu cases, public health efforts continue to emphasize vaccination and early treatment.
