In the week ending March 17, the CDC says 58 percent of confirmed flu cases were from the B-strain.
Health officials warn this strain tends to be more severe for younger children.
Here's some even more bad news.
If you were sickened by the A-strain earlier this season you can still catch a different strain.
You can still take some steps to protect yourself. The CDC says anyone who didn't get the flu shot this year can still get vaccinated.
