The child, who tested positive for influenza B, died sometime during the week of Sept. 30, although privacy concerns prevent officials from saying exactly where, CBS affiliate WTSP-TV reports.
Last flu season, 183 children in the U.S. died from flu or flu-related causes. That's the most since the Centers for Disease Control and Prevention (CDC) began keeping these records in 2004. Overall, an estimated 80,000 Americans died from flu last season.
The CDC recommends everyone age 6 months and older get vaccinated against the flu every year.
