What is hepatatis B?

Hepatitis B is a viral infection that attacks the liver, causing inflammation and potentially leading to serious health issues such as cirrhosis, liver cancer, and liver failure. It is caused by the hepatitis B virus (HBV), which is transmitted through contact with infectious body fluids, including blood, semen, and vaginal secretions. While some people can recover completely, others may develop chronic infections that require ongoing management. Vaccination is available and is the most effective way to prevent hepatitis B infection.
