*Includes H1N1 flu deaths April - Sept. 26, 2009 (13) and all flu deaths since Sept. 27, 2009

Starting Sept. 27, 2009 North Carolina expanded reporting of flu deaths to cover all deaths related to influenza, whether seasonal flu or pandemic H1N1 flu. As of Sept. 26, 2009, a total of 13 deaths attributed to laboratory-confirmed pandemic H1N1 flu had been reported in North Carolina.

Influenza-associated deaths are based on reports from doctors and local health departments of people who died from an illness identified as influenza (either seasonal or pandemic) through medical testing. In previous years, only pediatric flu deaths were reported. Reporting of all flu-related deaths, including those in adults, is now required.
