Viral hepatitis B, active component, U.S. Armed Forces, 2007-2016.

During 2007-2016, there were 1,258 and 1,259 incident diagnoses of acute and chronic hepatitis B virus (HBV) infection, respectively. The overall incidence rates of diagnoses of acute and chronic hepatitis B were both 10.0 per 100,000 person-years (p-yrs). Overall crude incidence rates of acute hepatitis B were highest among females, Navy members, Asian/Pacific Islander and non-Hispanic black service members, those in healthcare occupations, recruits, and service members with no history of deployment. Overall incidence rates of chronic hepatitis B were highest among service members who were female; in the Navy or the Army; in healthcare occupations; and of non-recruit status. Asian/Pacific Islander service members, those of other/unknown race/ethnicity, and non-Hispanic black service members had overall rates of chronic hepatitis B that were more than 41, 11, and 10 times that of non-Hispanic white service members, respectively. Crude annual incidence rates of acute hepatitis B fluctuated between 7.7 per 100,000 p-yrs and 13.2 per 100,000 p-yrs during the surveillance period. Approximately one of 10 acute cases and close to one of five chronic cases had at least one HBV-related hospitalization. Rates of hospitalized cases of acute hepatitis B decreased over the 10-year period.
