  • Hawaii 2011-2012 Flu Season: Weeks 44-28 (No New Deaths; Total One)

    Week 44:
    ILI: 1.6%
    P&I deaths: 12.9%
    No pediatric influenza-associated deaths since beginning of flu season.

    Since the beginning of the 201112 influenza season (MMWR week 40, 2011), a total of 1,127 specimens have been tested statewide for influenza viruses. Of these, 648 (57.5%) were screened only by rapid antigen tests whereas the remaining 479 (42.5%) underwent some type of confirmatory testing (either RT-PCR or viral culture). Altogether a total of 33 (2.9%) cases of influenza A and 10 (0.9%) cases of influenza B were detected using any method. Of the influenza A cases detected, 2 (6.1%) were 2009 H1N1, 17 (51.5%) were influenza A (H3), 1 (3.0%) were seasonal influenza A (H1), and the remaining (n = 13, 39.4%) were influenza A of unknown subtype.

    Of the 3.8% specimens that did test positive for influenza, more were likely to be aged 524 years than any other age group.
