Hepatitis B is a viral infection targeting the liver, capable of causing both acute and chronic illnesses. The virus is primarily transmitted from mother to child at birth but can also spread through exposure to infected blood and other bodily fluids.

According to the World Health Organization (WHO), by 2024, roughly 240 million people globally were living with chronic hepatitis B. Each year, about 900,000 new infections are reported, contributing to a significant health burden.

The disease led to approximately 1.1 million deaths in 2024, primarily due to complications such as cirrhosis and liver cancer. Despite its severe impact, hepatitis B is largely preventable through the use of safe and effective vaccines.
