As COVID-19 cases increase in the United States, flu activity continues to decrease sharply, according to the Centers for Disease Control and Prevention.

While the U.S. flu season is ebbing, it's still not over.

"Influenza-like illness activity, while lower than last week, is still elevated," the CDC said Friday.

The overall severity of this season's flu remains moderate to low.

The CDC estimates that so far there have been at least 24,000 deaths from flu, 39 million flu illnesses and 400,000 hospitalizations.
