Read Original Source
As flu season gets underway, global health experts are increasingly worried about a new strain of the virus that popped up in June — four months after the makeup of this year’s flu shots had been decided. Limited time: Save 25% on NBC News subscription Get exclusive reporting, live Q&As and ad-free reading. The new strain, a version of H3N2, is causing outbreaks in Canada and the U.K., where health officials are warning about the early wave that’s sending people to the hospital.
AI Summary
Main Idea: The World Health Organization says a new H3N2 flu strain is spreading quickly, and the United Kingdom is already seeing a severe early flu season.
Key Points:
- The new strain appeared after this year’s flu shots had already been planned, so the vaccine may not match it well.
- The United Kingdom says flu cases are far higher than this time last year, and hospitals are seeing an early wave.
- Canada and Japan are also reporting sharp rises in flu cases, which experts say are troubling signs for the Northern Hemisphere.
- U.S. flu tracking is less clear because the CDC has not released a full national update since Sept. 26, and experts say this could delay response efforts.
Impact on the People
Negative Impact
A more severe flu strain may bring more hospital visits, missed work, and extra strain on US families, hospitals, and small businesses if it spreads here.
Positive Impact
Flu shots can still lower the risk of severe illness and hospitalization, even if the match is not perfect.
