CDC update confirm severity of H1N1 over common flu

It is the most complete statistics on swine flu that I had ever come
across so far although it is localised to some place in USA that is
suffering with winter.

Before it was estimated that 80% of flu cases were swine flu.

This time, it is not just estimate but actual tests.

H1N1 Swine Flu Spreading Quickly
The Reach of H1N1 Swine Flu Spreads Daily

On November 4th, the Centers for Disease Control and Prevention (CDC)
issued an update on H1N1 swine flu statistics in the US current
through October 24th, week 42.

H1N1 Swine Flu vs. Regular Seasonal Flu

During the week of October 18-24, there were 19,642 specimens tested
for influenza virus. Of those, 8,268 (42.1 percent) tested positive
for some variety of flu virus. 21 specimens were influenza B, with
the remaining 8,247 being influenza A. 5,453 of those cases were
confirmed as H1N1 swine flu; the remainder either were not subtyped,
or the sub typing was unsuccessful. Not one single specimen
successfully subtyped showed either of the normal seasonal flu
subtypes (H1 and H3).

What is the Current Spread of H1N1?

Forty-eight states reported geographically widespread influenza
activity, Guam and two states reported regional influenza activity,
the District of Columbia and Puerto Rico reported local influenza
activity, and the U.S. Virgin Islands did not report.

Region 3 (DE, DC, MD, PA, VA, WV) and Region 7 (IA, KS, MO, NE)
reported the greatest percentage of cases that tested positive for
flu. Region 3 also had, by far, the greatest number of confirmed
H1N1 swine flu cases.

Other Important H1N1 Swine Flu Statistics in the Update

* There were 22 pediatric deaths associated with an influenza
virus during the week in question, 19 of which were confirmed H1N1
swine flu, and three whose subtype was undetermined. The child deaths
were located in Arizona [3], Florida, Georgia, Guam, Montana, Ohio,
South Dakota, Tennessee [2], Texas [9], Washington, and Wisconsin.
This brings the total flu-related deaths in children since August 30th
to 74, and 114 overall with the H1N1 virus. In contrast, there was
only one influenza-related pediatric death in the same week last year.
* The percentage of deaths associated with P&I (pneumonia and
influenza) was above epidemic levels. For the week in question, the
epidemic level is considered to be 6.6 percent of all deaths; it was
at 7.1 percent.
* All areas reporting had levels of ILI (influenza-like illness)
above the baseline for this time of year. the national baseline for
the week in question is 2.3 percent; but the week's figures were right
at 8 percent.
