The United States has seen the number of influenza cases climb significantly in December, coming after the most severe flu season since 2018, the Centers for Disease Control and Prevention (CDC) said.
It’s not yet clear whether there will be an increase in the total number of people who get the flu this season – or whether more people just got it at once in December – but more than 3,100 people died from the virus in the US in the year ending August 2025, according to the latest data from the CDC.
