Deadliest flu season since 2010
The virus has taken 172 lives this season, making it the deadliest season since 2010, per the AP, and it is reaching a peak at 14,000 new infections each week, according to CBS. The CDC has a great interactive map to track states and flu activity this season.
The good news: The Centers for Disease Control reports this year's vaccine is closely matched for the main strain this year, influenza A, which includes predominantly H3N2 strains, and that there's still time left to get the shot. There are also some trailing cases of H1N1 this year.
