Week 5 Isolates Chart. Like so many other states, AH3N2 is decreasing and both Influenza B and pH1N1 are increasing. There must be some immunological reason that Influenza B can co-circulate with pH1N1 while H3N2 cannot.

The %ILI is still rising and is at a level that currently exceeds levels seen during the peak of the Pandemic and the 2007-08 seasonal peak.

Re: North Carolina 2010-2011 Season: Weeks 40-6 (Three New Deaths; Total 14)

Re: North Carolina 2010-2011 Season: Weeks 40-6 (Three New Deaths; Total 14)

Of the 14 deaths reported in NC, 6 are pediatric deaths. The overall percentage of pediatric deaths to total reported deaths in the 2009-10 was ~12%. I know the sample size is small in comparison, but NC does require reporting of adult influenza deaths. I hope this is just an anomaly, but that is 4x the death rate for children during the pandemic.

In the 2009-10 season, NC had 7 pediatric deaths out of 107 total deaths.

The chart shows the age groups of deaths in NC. There was an additional pediatric death reported since last week, so that 7 of 18 deaths have been pediatric deaths in NC, which at 39%, is 3x the percent pediatric deaths from 2009-10 in the U.S.

Re: North Carolina 2010-2011 Season: Weeks 40-8 (No New Deaths; Total 22)

Re: North Carolina 2010-2011 Season: Weeks 40-8 (No New Deaths; Total 22)

North Carolina is reporting no deaths in Week 8, but has added 4 deaths to the total from prior weeks, including one pediatric death.

Eight pediatric deaths out of 22 is a very high ratio (more than a third) of pediatric deaths. During the 2009-10 season pediatric deaths represented ~12% of the reported deaths. In a typical year, it's probably <5%.
