Re: Hawaii 2011-2012 Flu Season: Weeks 44-48

Week 48:
ILI: 1.9%
P&I deaths: 8.5%
Since the season began, a total of 43 (2.2%) cases of influenza A and 14 (0.7%) cases of influenza B were detected using any method. Of the influenza A cases detected, 3 (7.0%) were 2009 H1N1, 20 (46.5%) were influenza A (H3), 1 (2.3%) were seasonal influenza A (H1), and the remaining (n = 19, 44.2%) were influenza A of unknown subtype.
NOTE: WHO "strongly recommends that all un-subtypable influenza A specimens should be immediately sent for diagnosis and further characterization..." http://www.who.int/influenza/human_a.../en/index.html

Of the 2.9% specimens that did test positive for influenza, more were likely to be aged 5–24 years than any other age group.
