WASHINGTON (AP) - District of Columbia health officials say flu cases in the city have more than tripled since last flu season - with about half of the season remaining.
The city's health department says hospitals have reported 310 cases of influenza since the season began in late September. Just since Jan. 1, there have been 40 new cases.
Last flu season, there were 97 reported cases. The season ran from early October to late May.
Officials say no one has died from the flu this season.
Health officials are urging residents to get vaccinated and say the vaccine is still widely available.
The Centers for Disease Control and Prevention reported in late December that the district was one of just a few states and territories not experiencing "widespread" flu outbreaks.
