Novel H1N1 influenza hospitalizations: Minneapolis-St. Paul metropolitan area, 2008-2009.
The influenza season of 2008-2009 will be remembered for the initial wave of novel influenza A (nH1N1) that was noted in the spring. This strain of influenza rapidly spread throughout the United States and Minnesota. Notable features in Minnesota include a higher incidence rate among children, a higher proportion of patients who also had asthma, and a higher incidence rate of pneumonia at discharge among hospitalized nH1N1 cases compared with seasonal influenza A cases.
