Flu Remains 'Elevated' in U.S — CDC

Flu season has peaked, but nasty strain is on rise: report

Flu season has peaked, but nasty strain is on rise: report

The flu was geographically widespread in 48 states and Puerto Rico during the week ending March 2, though a CDC forecast has said there's "about a 90 percent chance that the flu season has peaked nationally". However, over the last two weeks, more illnesses have been tied to the Type A H3N2 strain, which poses a more significant risk to the elderly.

Overall, severity markers such as hospitalizations and deaths continue increase, as they typically do later in the flu season, but the levels are substantially lower than last season, which was severe. But that strain has been present - and vigorous in Nebraska for most of this flu season. Earlier this year, the prominence of H3N2 led World Health Organization officials to postpone the decision about which strains should go into this year's flu vaccine. Out of those deaths, 64 were children. And at public health labs, of subtyped influenza A viruses last week, 62% were H3N2 and 38% were 2009 H1N1.

"Although it's not ideal, it still prevents many, many infections, and even if you should get influenza despite having received the vaccine, it tends to make a less severe infection".

333 people died during the previous flu season. "You are certainly less likely to get the complications of pneumonia, having to be hospitalized and dying", Schaffner said.
