Wisconsin and the entire country is experiencing a significant increase in influenza activity, with outbreaks in schools, long-term care and communities. According to the Wisconsin immunization report
prepared by Jon Temte, MD, in Wisconsin, 85 percent of recent detections are influenza A and 97 percent of A viruses are H3N2. There have been 837 influenza-related hospitalizations since September 1, 2016, with 97 admitted to ICU and 12 requiring mechanical ventilation. This compares to 163 hospitalizations last year at this time, and 3,763 for the 2014-2015 season. Sixty-six percent of hospitalizations have been in individuals age 65 and older. Influenza A[H3N2] is less kind to elders; across the U.S. one out of every 870 people age ≥65 has been hospitalized with laboratory-confirmed influenza.
