• Description:
  In comparison to other recent seasons, the 2012-2013 season was moderately severe, with a high percentage of outpatient visits for influenza-like illness (ILI), high rates of hospitalization (particularly among people 65 years and older), and more reported deaths attributed to pneumonia and influenza compared with recent years. This season had a somewhat early increase in flu activity through November and December, with a peak in late December. Influenza-like-illness rose quickly to well above the baseline of expected activity and remained elevated for 15 consecutive weeks, making this season slightly longer than average.
