Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
It is commonly transmitted from mother to child during birth but can also spread through contact with infected blood or other body fluids.
According to the World Health Organization (WHO), an estimated 240 million people were living with chronic hepatitis B in 2024, with about 0.9 million new infections recorded annually.
The disease caused an estimated 1.1 million deaths in 2024, mainly due to cirrhosis and liver cancer.
Despite its heavy toll, hepatitis B can be prevented through safe, effective vaccines.
