Rising Flu Cases Hit Older Adults Harder

Flu cases in the U.S. are rising due to a new H3N2 strain, which may reduce vaccine effectiveness, especially affecting older adults. Despite concerns, health officials believe vaccines still offer protection against severe illness. The flu season is not yet at its peak, but hospitalizations and deaths are increasing, with the Northeast experiencing a significant surge. Winter conditions facilitate the spread of airborne viruses, and vaccination remains crucial to reduce severity and hospitalizations. COVID-19 levels are lower than during peak summer waves, but vigilance is still advised.
