In this characterization of 1088 cases of H1N1 that were either hospitalized or died between April-August 2009 in California, researchers found that 2/3 of the patients had abnormal chest xrays, 1/3 had false negative antigen testing, 2/3 had risk factors for complications, and 1/3 were admitted to the ICU. Median age was 27, overall mortality was 11%, and the highest risk of death (once hospitalized) was in those > age 50. Secondary bacterial infection was rare (4%) (abstract).
