Flu making comeback in U.S. after unusual year off

The U.S. flu season has arrived on schedule after taking a year off, with flu hospitalizations rising and two child deaths reported.

Last year’s flu season was the lowest on record, likely because COVID-19 measures — school closures, distancing, masks and canceled travel — prevented the spread of influenza, or because the coronavirus pushed aside other viruses.

“This is setting itself up to be more of a normal flu season,” said Lynnette Brammer, who tracks flu-like illnesses for the U.S. Centers for Disease Control and Prevention.

The childhood deaths, Brammer said, are “unfortunately what we would expect when flu activity picks up. It’s a sad reminder of how severe flu can be.”

During last year’s unusually light flu season, one child died. In contrast, 199 children died from flu two years ago, and 144 the year before that.

In the newest data, the most intense flu activity was in the nation’s capital, Washington, D.C., and the number of states with high flu activity rose from three to seven. In CDC figures released Monday, states with high flu activity are New Mexico, Kansas, Indiana, New Jersey, Tennessee, Georgia and North Dakota.

The type of virus circulating this year tends to cause the largest amount of severe disease, especially in the elderly and the very young, Brammer said.
