Type B flu viruses are on the rise while overall rates drop

Flu infection rates continued dropping during the week ending Feb. 24 but influenza is still very active, the Centers for Disease Control and Prevention said Friday. And, the CDC reported another 17 pediatric deaths during that week, meaning 114 kids have died so far from the flu this season — already higher than the prior two years (110 last year and 93 the year before).

What you need to know: People are now reporting higher infections of influenza B viruses so it's possible there could be a second bump to the season, The Washington Post points out. CDC officials said earlier that it's possible to get the flu more than once in a season, and they still recommend people get a flu shot, which is estimated to be 42% effective against Influenza B for all ages.
