What is the disease caused by the HBV virus?

The disease caused by the HBV virus is Hepatitis B. Hepatitis B is a serious liver infection transmitted through contact with infectious body fluids, such as blood, semen, or vaginal fluids, which may occur through sexual contact, sharing of needles, or from mother to child at birth. The HBV virus can lead to chronic liver disease, cirrhosis, and even liver cancer over time.

Understanding the distinctions between the various types of hepatitis is crucial. Hepatitis A is caused by a different virus and is usually transmitted through contaminated food and water. Hepatitis C is caused by the HCV virus and is primarily spread through blood-to-blood contact. Hepatitis D is unique in that it only occurs in those who are already infected with Hepatitis B, as it depends on the presence of the HBV virus for its replication. Each type has its own mode of transmission, symptoms, and potential complications, making the identification of the correct viral cause important for treatment and prevention efforts.
