    Flu activity so far

    According to Friday's Weekly Influenza Surveillance report from CDC, 16 states were experiencing widespread flu activity in the week ending in Nov. 30, while Kansas, Rhode Island, Washington, D.C., and West Virginia were experiencing sporadic flu activity.

    Meanwhile, 31 states were experiencing local or regional flu activity:

    This flu season has been worse than last year's so far, according to the report. For example, the data shows the cumulative hospitalization rate for the flu is 2.7 per 100,000 people this season, compared with 1.8 per 100,000 at the same point last season.

    CDC last week also published its burden estimates for the 2019-2020 flu season. According to CDC, this year's flu season has led to at least 800,000 medical visits and 16,000 hospitalizations. The data also shows that between 910 and 2,400 flu-related deaths occurred from Oct. 1, 2019, to Nov. 30, 2019. The agency said six pediatric deaths have been reported this flu season, including one during the week ending in Nov. 30. In addition, CDC found that the percentage of outpatient visits for influenza-like illness increased to 3.5% this week, above the national baseline of 2.4%.

    According to CDC officials, a barrage of illnesses across the South—thanks to a surprise strain of the flu virus—is behind the quick escalation of this year's flu season. That strain of virus isn't as dangerous to older people, experts said. Scott Epperson, who tracks flu-like illnesses for CDC, said there's a chance the flu season could peak this month, which would be much earlier than when it usually peaks, around February.

    "It really depends on what viruses are circulating," Epperson said. "There's not a predictable trend as far as if it's early it's going to be more severe, or later, less severe" (CDC Weekly U.S. Influenza Surveillance Report, accessed 12/9; CDC "Flu View," accessed 12/9; AP/NBC News, 12/7).
