What causes hepatitis B?

Hepatitis B is caused by a virus known as the hepatitis B virus (HBV). This virus specifically targets the liver and can lead to acute and chronic liver diseases, including cirrhosis and liver cancer. Understanding that hepatitis B is viral in nature is crucial for both prevention and treatment.

Viral infections are distinct from bacterial infections, fungal infections, and genetic disorders. While bacteria and fungi can cause a variety of health issues, they are not responsible for hepatitis B. Similarly, genetic disorders involve inherited conditions that are not linked to viral infections like hepatitis B. Therefore, recognizing that hepatitis B is specifically related to a viral infection underlines the importance of vaccination and risk-reduction strategies in its prevention.
