So What?
1) The Centers for Disease Control and Prevention collects, compiles, and analyzes information on influenza activity year round
in the United States. The surveillance system is a collaboration between the CDC and public and private health care providers
and vital statistics offices around the U.S.
2) This graph plots the number of pediatric (less than 18 year olds) deaths each week attributed to influenza plotted throughout
flu season around the chart over multiple seasons. The CDC defines the official flu season starting each year at week 40, in
early October. The distance from the center indicates more pediatric deaths due to influenza, with the middle being zero.
3) One can see a general pattern for the incidence of pediatric flu deaths between weeks 7 and 16 of the year, between
mid-February and mid-April each year.
4) There was a secondary outbreak around week 25 of the 2008-09 season, around mid-June.
5) One can see a very early and severe increase in pediatric deaths starting at week 38 of the 2008-09 season, in late
September, peaking during weeks 44 (Oct/Nov) and 46 (November), then fading by week 50 (December). This is likely due to
the 2009 Influenza A (H1N1) (swine flu).
6) Pediatric deaths peaked in the 2009-10 season with weekly deaths more than three times the peak of the other seasons
plotted, again likely due to the 2009 Influenza A (H1N1) (swine flu).
7) Note that this chart tells us nothing about the number of flu cases not resulting in death, nor non-pediatric cases. It does
tend to indicate the timeframe and severity of flu for pediatric patients.
