During 2011–2019, rates of reported acute hepatitis B steadily increased among persons aged 40–49 and 50–59 years. In contrast, rates continued to remain low among children and adolescents aged 0–19 years. During 2015–2019, rates of reported acute hepatitis B have decreased by 86% among persons aged 20–29 years, likely explained, in part, because of the implementation of childhood hepatitis B vaccine recommendations in 1991. As the cohort of persons aged 20–29 years has grown older, rates of acute hepatitis B among persons aged 30–39 years began to consistently decrease beginning in 2015.
