*Key Flu Indicators*

Each week CDC analyzes information about influenza disease activity in the United
States and publishes findings of key flu indicators in a report called FluView [
http://www.cdc.gov/flu/weekly/ ]. During the week of December 27, 2009-January 2,
2010, most key indicators declined compared to the previous week. Below is a summary
of the most recent key indicators:

  * Visits to doctors [ http://www.cdc.gov/flu/weekly/index.htm ] for influenza-like
illness (ILI) nationally decreased this week over last week. Visits to doctors for
ILI also are examined by region. ILI increased in 4 regions, but decreased in 6
regions of the country.
  * Overall hospitalization [ http://www.cdc.gov/flu/weekly/index.htm#HS ] rates for
this season were unchanged from the previous week in all age groups.
  * The proportion of deaths  [ http://www.cdc.gov/flu/weekly/index.htm#MS
]attributed to pneumonia and influenza (P&I) based on the 122 Cities Report
decreased over the previous week and is back below the epidemic threshold. (The
epidemic threshold is the point at which the observed proportion of deaths
attributed to pneumonia or influenza is significantly higher than would be
expected at that time of the year in the absence of substantial influenza-related
mortality.) In addition, another four
 flu-related pediatric deaths [ http://www.cdc.gov/h1n1flu/updates/us/#pedh1n1cases
] were reported this week: all four of these deaths were associated with laboratory
confirmed 2009 H1N1. Since April 2009, CDC has received reports of 293
laboratory-confirmed pediatric deaths: 248 due to 2009 H1N1, 43 pediatric deaths
that were laboratory confirmed as influenza, but the flu virus subtype was not
determined, and two pediatric deaths that were associated with seasonal influenza
viruses.
 (Laboratory-confirmed deaths are thought to represent an undercount [
http://www.cdc.gov/h1n1flu/estimates_2009_h1n1.htm#UnderCounting#UnderCounting ] of
the actual number. CDC has provided estimates about the number of 2009 H1N1 cases
and related hospitalizations and deaths [
http://www.cdc.gov/h1n1flu/estimates_2009_h1n1.htm ].
  * One state (Alabama) continues to report widespread influenza activity [
http://www.cdc.gov/h1n1flu/updates/us/ ]; a decline of three states from last
week.  Twelve states continue to report regional influenza activity. They are:
California, Georgia, Hawaii, Indiana, Maine, Nevada, New Hampshire, New Jersey,
New Mexico, New York, Tennessee, and Virginia.
