- Hepatitis B is caused by the hepatitis B virus (HBV) and can cause liver inflammation, vomiting, jaundice, and rarely death. It can become chronic and lead to cirrhosis or liver cancer. - HBV is highly resistant and can survive for long periods outside the body. It is transmitted through bodily fluids and sexually, through blood transfusions, needle sharing, and from mother to child during birth. - HBV infection leads to liver damage as the immune system attacks the liver. Chronic infection can happen if the immune response is impaired or tolerant, possibly leading to cirrhosis or liver cancer.
