Percentage of Deaths Attributed to Influenza...

CDPH receives weekly year-to-date dynamic data on deaths occurring in California from the CDPH Center for Health Statistics and Informatics. These data are limited to deaths occurring in California residents and are analyzed to identify influenza-coded deaths. Influenza-coded deaths are defined as deaths with influenza noted in any cause of death field on the death certificate (influenza specified in a literal [text] cause of death field or an influenza ICD-10 code in a coded cause of death field). Influenza-coded deaths are not necessarily laboratory-confirmed and are likely to be an underestimate of all influenza-associated deaths. CDPH calculates the percentage of influenza-coded deaths by dividing the number of influenza-coded deaths by the total number of all cause deaths during the same period.
