    Week 52 (12/21/2014 ? 12/27/2014)
    2014-2015 Season (9/28/2014 ? 10/3/2015)

    Influenza activity highlights:
    ? 317 laboratory-confirmed cases of influenza were reported in the past week, from twelve counties.
    941 cases have been reported this season, with laboratory-confirmed cases identified in fourteen
    counties.
    ? 840 (89%) reports this season are influenza A, 78 (8%) are influenza B, and 23 (3%) are of unknown
    type.
    ? In the past week, 127 (84%) of 152 specimens tested positive for influenza at ASPHL: 124 influenza
    A (H3) viruses and 3 influenza B viruses.
    ? Influenza-like illness activity at sentinel providers was below Arizona?s threshold in week 51;
    however, not many providers have reported data for this week, so this may not be representative of all
    providers.
    ? New influenza-like illness data for sentinel schools was not available due to the winter break.
    ? One influenza-associated pediatric death has been reported for the 2014-2015 season in Pima County.
    This case had underlying conditions and was PCR positive for influenza A (H3).

    ? The cases included in this report represent a small proportion of the true number of cases of influenza.
    Many people do not visit the doctor when ill and doctors should not be expected to run tests on all
    patients exhibiting influenza-like symptoms.
