There are five main types of hepatitis viruses: A, B, C, D and E. Hepatitis B and C are the two main types that can cause chronic disease in infected individuals and are the most common causes of cirrhosis and cancer. Viral hepatitis is the seventh leading cause of death worldwide, on par with deaths caused by tuberculosis and HIV; the total number of people infected with hepatitis C reaches 71 million worldwide, and there is no effective vaccine for hepatitis C. In addition, diagnosis rates and treatment access for hepatitis B and C remain low at present, but despite the increase in the total number of deaths due to hepatitis, the number of new hepatitis B infections is also showing a downward trend due to an increase in hepatitis B vaccination coverage in children. In 2016, WHO adopted the Global Health Sector Strategy for Viral Hepatitis, which identifies two targets to be achieved in 2030 in the fight against hepatitis. Dr. Ivan Hewdin, WHO’s technical lead for global hepatitis planning, noted that there is still a big gap to this goal, “We have started to act, but there is still a big gap to what we will achieve by 2030, which is to increase the proportion of people tested for hepatitis B and C to 90% and the proportion treated to 80%. WHO experts say viral hepatitis is seen as a major public health challenge that requires an urgent response. There are already vaccines and medicines that address hepatitis, and WHO is committed to promoting and ensuring that they reach all those who need them.
