Investigators used data from the Global Burden of Disease Study to estimate global morbidity and mortality from acute viral hepatitis and hepatitis-virus-related cirrhosis and liver cancer from 1990 to 2013. Viruses studied included hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV), and hepatitis E (HEV).
Between 1990 and 2013, deaths from viral hepatitis increased 63%, from 0.89 million to 1.45 million, and disability (measured as disability-adjusted life-years or DALYs) increased 34%, from 31.7 million to 42.5 million. The absolute increases in morbidity and disability were driven primarily by population growth.
HBV and HCV accounted for 96% of hepatitis-related deaths and 91% of hepatitis-related DALYs in 2013. HBV- and HCV-related m…
