Site-level data not shown for 2401 persons (2%) from 6 sites who participated in FluSurv-NET surveillance for 3 or fewer of 10 influenza seasons (Iowa, Idaho, North Dakota, Oklahoma, Rhode Island, South Dakota).
During the 2017 to 2018 season, California, Georgia, New Mexico, Ohio, Oregon, and Albany, New York, conducted medical record abstractions on a 50% random sample of adults aged 50 to 64 years and a 25% random sample of adults aged 65 years or older. During the 2018 to 2019 season, these same sites conducted medical record abstractions on a 50% random sample of adults aged 65 years or older. These sites conducted medical chart abstractions on 100% of persons in all other age groups and seasons.
During the 2017 to 2018 season, Minnesota conducted medical record abstractions on a 50% random sample of adults aged 65 years or older. Minnesota conducted medical record abstractions on 100% of persons in all other age groups and seasons.
