CDC warns of a second wave of flu virus, happening now

TAMPA, Fla. (WFLA) - 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.

The Florida Department of Health reports that flu activity has decreased but it is well above the national baseline. Despite the decrease, levels are similar to peak activity observed during the 2016-17 season, indicating this season is not over yet. 

In Florida this week, influenza A (H3) has been the most common strain of influenza identified, however, influenza B activity has continued to increase in recent weeks. The late-season circulation of influenza B is expected, according to the Florida Department of Health.

Remember, it’s never too late to get the flu shot.

Information from WTNH and WTEN was included in this report.
