Hepatitis B - Summary
Hepatitis B
Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). The liver is an important organ that helps in processing nutrients, filtering blood, and fighting infections. When someone gets hepatitis, it can cause inflammation or damage to the liver, affecting its key functions. Many factors can lead to hepatitis, like heavy consumption of alcohol, exposure to toxins, certain medications, and specific medical conditions.
Hepatitis is mostly caused by a virus. In India and across the world, the major types of viral hepatitis include Hepatitis A, Hepatitis B, and Hepatitis C.
Understanding Hepatitis B Virus (HBV)
The hepatitis B virus (HBV) is responsible for both acute and chronic liver disease and is found in many parts of the world. This virus spreads through direct contact with the blood or other body fluids of an infected person.
- When the virus is passed from a mother to her child (vertical transmission) or spreads among young children (horizontal transmission), it often leads to a chronic infection.
- In older children and adults, the virus spreads mainly through sexual contact, sharing of contaminated needles, or, less commonly, through blood transfusions. In such cases, the infection may go away unless the person has a weak immune system, like those who are infected with the human immunodeficiency virus.
- Learning about and practising safe methods is very important to prevent the spread of HBV.
- HBV is a significant risk for healthcare workers, who must take precautions.
- Luckily, a safe and effective vaccine against HBV has been available since 1982, offering 95% protection against new infections.
