Flu season is winding down, but the Centers for Disease Control is warning of a second wave, Flu Virus B, which is happening right now.
The CDC says that B-viruses are being reported more frequently than the A-strain, which had been more dominant recently. A CDC spokesperson says B-strain viruses tend to be more severe for younger children.
Experts say it’s possible for those who have already been sick with the flu to fall ill again with a different strain later in the season.
According to the CDC, Kansas is reporting moderate flu activity in the state.
