Some statistics about hepatitis B viral infection

Approximately 90% of infants infected at birth and 25%- 50% of infected children aged 1-5 years have chronic persistent infection.
• Approximately 20% of people with chronic hepatitis B infection have their lives shortened by complications of liver disease, cirrhosis, or liver cancer.
