* Rates per 100,000 population.
† Reported confirmed cases. For the case definition, see Chronic Hepatitis B.
§ Numbers reported in each category may not add up to the total number of reported cases in a year due to cases with missing data or, in the case of race/ethnicity, cases categorized as “Other”.
¶ Urban-rural region was categorized according to the 2013 National Center for Health Statistics (NCHS) urban-rural classification scheme for counties and county-equivalent entities. Large central metro, large fringe metro, medium metro, and small metro counties were grouped as urban. Micropolitan and noncore counties were grouped as rural.
** US Department of Health and Human Services Regions were categorized according to the grouping of states and US territories assigned under each of the ten Department of Health and Human Services regional offices. For the purposes of this report, regions with US territories (Region 2 and Region 9) contain data from states only.
During 2020, the rate of newly reported cases of chronic hepatitis B was highest among persons aged 30–39 and 40–49 years and accounted for 46% of all chronic hepatitis B cases reported during 2020. The highest rate of newly reported chronic hepatitis B cases occurred in urban areas, as defined by the National Center for Health Statistics, and among US Department of Health and Human Services Region 4 (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee).
Although the rate of reported acute hepatitis B was the lowest among Asian/ Pacific Islander persons (Figure 2.6), the rate of newly reported chronic hepatitis B was highest among Asian/Pacific Islander persons (17.6 cases per 100,000 population) and was almost 12 times the rate among non-Hispanic White persons (1.5 cases per 100,000 population).
Race/ethnicity information was only available for 7,558 (65%) cases of newly reported chronic hepatitis B. Because the majority of prevalent chronic hepatitis B virus infections in the United States are among persons who are non-US-born, differences in the rates of newly reported chronic hepatitis B by race/ethnicity are likely influenced by country of birth. However, country of birth is not routinely collected in the National Notifiable Diseases Surveillance System.
