"Viral hepatitis accounts for a significant global disease burden and high mortality from liver cancer and cirrhosis. In 2019, 296 million people were living with chronic hepatitis B virus infection and 58 million people with chronic hepatitis C virus infection worldwide. New estimates show that about 1.5 million people newly acquire hepatitis B infection each year, despite the availability of a highly efficacious vaccine. About 1.5 million people newly acquire hepatitis C virus infection. Viral hepatitis caused 1.1 million deaths in 2019, 96% of which were caused by hepatitis B and C virus (5). Most of these deaths result from chronic liver disease and liver cancer. The greatest burden of hepatitis B and C infection is concentrated by geography and population, with 80% of the global burden of hepatitis C infection in the 10 most severely affected countries. People from economically disadvantaged regions, displaced people and migrants, and rural populations are more severely affected. Further, injecting drug use is a major contributor to the hepatitis C epidemic globally (6). Other affected population groups include health-care workers exposed through needle-stick injuries, people in prisons and closed settings, and gay men and other men who have sex with men."
