About Hepatitis B

Hepatitis B virus (HBV) is a DNA virus that infects liver cells and can become chronic if the immune system is not able to clear the virus after an acute infection.

Roughly 450 million people worldwide live with chronic HBV, with 1 million deaths due to HBV-related illnesses.

HBV is a major public health burden in China with 73 million infections in 2019. About 80% of patients develop primary liver cancer or cirrhosis due to chronic HBV infection.

Antiviral drugs have been used effectively to control the disease, but cure rates are very low (less than eight percent cured after four years of daily oral antiviral therapy).
