Elimination of Hepatitis B virus transmission in an endemic area in Western Alaska.

ABSTRACT:

Objectives

In the US, hepatitis B virus (HBV) is only endemic in western Alaska, where 90% of the population are Alaska Native (AN) peoples; in the 1970s, the incidence of hepatocellular carcinoma (HCC) in children was the highest in the world. In the 1980s, we screened 53,860 AN peoples for HBV infection, administered HBV vaccine to 43,618 HBV seronegative persons, and initiated universal newborn vaccination. In this study, we examine the impact of this effort 40 years later.

Methods

This is a population-based outcome study. We used vaccine and electronic health records to examine rates of newborn vaccination between 2015 and 2019 and changes in HBV incidence rates, as well as the prevalence of HCC in persons under 30 years of age over a 50-year period.
