(CNN) - Flu season is winding down, but the latest report from the Centers for Disease Control and Prevention says that B-viruses are being reported more frequently than the A-strain that had been dominant recently.
During the week ending March 17, nearly 58 percent of all confirmed cases of the flu were caused by the B-strain.
A CDC spokeswoman says B-strain flu viruses tend to be more severe for younger children.

Experts say it's possible for those who've already been sick with the flu to fall ill again with a different strain later in the season.
They recommend everyone who is unvaccinated, get a flu shot while strains are still circulating.
