Table 1: Hepatitis B and C disease burden, by country in the WHO Western Pacific Region
Reliable epidemiological estimates for hepatitis B and C are not available for many countries in the Region. Presented in this table is estimated prevalence of chronic HBV and HCV in the Western Pacific Region.
NOTE: updated as of 23 July 2018
HBsAg - hepatitis B surface antigen
HCV RNA - hepatitis C RNA viral load

Cirrhosis and liver cancer cause most hepatitis-related deaths
Most (97%) deaths due to viral hepatitis in the WHO Western Pacific Region, are the result of chronic hepatitis B and C related cirrhosis or hepatocellular carcinoma (liver cancer). An estimated 3% of deaths in the region are attributed to acute hepatitis B and E related-complications.
In 2016, most deaths from chronic hepatitis occurred in China, followed by Japan and Viet Nam.
The WHO Western Pacific Region (WPRO) has a high burden of hepatitis B and C with high incidence rates of liver cancer in many countries.
