NOTES
  • Data source: Hepatitis Elimination and Epidemiology Dataset (HEED), as of January 2023.
  • An HCV diagnosis is determined by a positive HCV RNA test (quantitative or qualitative) or genotype test. The year of HCV diagnosis is based on the date of the earliest positive HCV RNA or genotype test since January 1, 2010. Some individuals, especially those appearing here in 2010-2011, may have been first diagnosed prior to 2010, resulting in the inflation of numbers and rates of diagnoses for these years. Numbers and rates from 2010-2011 should be interpreted with caution.
  • All rates shown are per 100,000 population as of 2020.
  • Neighborhood Tabulation Areas or NTAs, are aggregations of census tracts that are subsets of New York City’s 55 Public Use Microdata Areas (PUMAs).
  • Stratification by age is available in 7 categories(<20, 20-29, 30-39, 40-49, 50-59, 60-69, 70+) for New York State, NYS (excluding NYC), region, New York City, and NYC borough. At the county level (excluding NYC counties) and NYC NTA level (map view only), age groups are limited to 2 categories (<40 and 40+).
  • Data by age group and sex combined is not available at the county level or NYC NTA level.
  • Data on sex/gender are obtained primarily through laboratory reports, which may not reflect the gender identity of the individual. Data filtered by sex excludes two recorded HCV diagnoses to a transgender person in New York State.
