Confirmed Case Reports  Between 9/1/2009 and 6/5/2010, 831 laboratory-confirmed H1N1 cases have been reported in Idaho; 57% were female,  43% were male, and the median age of all case reports was 22 years (range: 1 month–96 years). Figure 1: Confirmed cases by report date. Figure 2: Confirmed case reports, by health district. For the locations of all seven Idaho Health Districts, see our Where to get Vaccinated page Figure 3: Confirmed H1N1 influenza cases, by 10 year age group. Laboratory confirmation is defined as a positive test for the 2009 H1N1 virus performed by either the Idaho Bureau of Laboratories or a commercial laboratory offering H1N1 confirmation. The Idaho Bureau of Laboratories limits testing to those hospitalized with suspected influenza, persons working in a hospital setting, pregnant women, or in support of a public health district outbreak investigation. The total number of case reports presented here is considered an underestimation of 2009 H1N1 activity in Idaho, as persons with mild illness may not seek medical attention, persons may seek medical attention but not be tested, or persons may be tested too late in the course of illness to detect the virus.   An additional 340 confirmed 2009 H1N1 cases were reported in Idaho prior to September 1, 2009.

Influenza-Associated Hospitalizations:  Between 9/1/2009 and 6/5/2010, 389 influenza-associated hospitalizations were reported in Idaho; 46.5% were male, 53.5% were female and the median age was 32 years (range: <1–87 years). Hospitalizations are considered influenza-associated when any influenza-specific test is positive (e.g., a rapid influenza test, DFA, or H1N1 confirmatory test).   Figure 4: Hospitalized cases are shown by 10 year age group. Underlying medical conditions: Detailed clinical information was available for 51.9% of hospitalized cases and of those, 84% had some kind of underlying medical condition: cardiovascular disease, chronic metabolic disease (such as diabetes) and asthma were the top three reported.  Detailed clinical information was available for 202 of the 389 (51.9%) of hospitalized cases. Of these 202 hospitalized cases, 17 (8%) were pregnant.  -back to top-
Influenza-Associated Mortality, by Month:  Between 9/1/2009 and 6/5/2010, 23 laboratory-confirmed H1N1-associated deaths were reported; 52% of deaths were male, 48% were female and the median age of fatal cases was 50 years (range: <1 year–83 years). Laboratory confirmation is defined as a positive test for the 2009 H1N1 virus carried out by either the Idaho Bureau of Laboratories or a commercial laboratory offering 2009 H1N1 confirmation.     Figure 5: Confirmed H1N1-associated deaths are shown by month of death. Twelve were reported with underlying conditions including cancer, chronic obstructive pulmonary disease (COPD), developmental delay, diabetes, heart disease and liver disease.     -back to top-
