During 2010-11 the percent positive for influenza virus peaked at 36%: 74% A and 26% B with influenza A (H3N2) being predominant over 2009 influenza A (H1N1). Currently, ~80% A and ~20% B, A(H3N2) predominant. Showing peak at 37%?
During the 2010-11 influenza season, P&I exceeded the epidemic threshold for 9 weeks. Current season, P&I has been at or slightly exceeded threshold only four times) since week 40.
From October 3, 2010, to May 21, 2011, 122 laboratory-confirmed influenza-associated pediatric deaths were reported. (Of 105 deaths, 40 were associated with influenza B viruses, 27 with 2009 influenza A (H1N1) virus, 18 with influenza A (H3N2) viruses, and 20 with influenza A virus for which the subtype was not determined) Currently around 37 pediatric influenza-associated deaths have been reported. (Of 29 deaths, 10 were associated with influenza B and 19 with influenza A). http://gis.cdc.gov/GRASP/Fluview/PedFluDeath.html
88 influenza-associated pediatric deaths were reported for the 2007-08 season; A (H3) predominated with 28.7% B; above the epidemic threshold for 13 consecutive weeks.
Season 2010-11 (at peak of recorded hospitalizations) per 100,000 vs current season per 100,000:
Age group 5-17: (9.1) vs currently (4.8) ~2x less than 2010-11
Age group 18-49: (11.4) vs currently (5.6) ~2x less than 2010-11
Age group 50-64: (21.9) vs currently (12.1) ~2x less than 2010-11
Age group 0-4yr: (46.2) vs currently (22.4) ~2x less than 2010-11
Age group >64 : (64.0) vs currently (53.4)
In 2010-11, hospitalization rates overall were similar to rates reported during the 2007-08 influenza season, when influenza A (H3N2) was the predominant strain and was less severe than the pandemic year (2009-10) and the 2007-08 season, but more severe than the 2008-09 influenza season, as determined by the percentage of deaths resulting from pneumonia or influenza, the number of influenza-associated pediatric deaths reported, and the percentage of visits to outpatient clinics for ILI.
Looking at the current data, the only age group that may exceed the 2010-11 hospitalization rate is 65 and older, unless the reporting lag changes things drastically.
