Hepatitis B control in the World Health Organization's Western Pacific Region: targets, strategies, status

Abstract

WHO's Western Pacific Region has the highest rates of hepatitis B virus (HBV) infection in the world; most countries have >8% prevalence of HBV chronic infection in their adult population. In 2005, Member States of the Region adopted a resolution to reduce chronic hepatitis B infection prevalence to less than 2% among children by 2012 as an interim milestone toward a regional goal of less than 1% prevalence. Country commitments to hepatitis B control and successes represent a remarkable public health achievement by preventing over 1 million chronic infections and 300,000 HBV-related deaths per birth cohort. Reported here is a review of the process and strategies for translating this public health initiative into practice including such activities as setting up an Expert Resource Panel, developing implementation guidelines, focusing on facility births while supporting efforts to reach home births, providing guidance for conducting seroprevalence surveys, and establishing a verification process.
