Which virus is specifically associated with liver infection transmitted through blood exposure?

The Hepatitis B Virus (HBV) is specifically associated with liver infection and is transmitted primarily through exposure to infectious body fluids, particularly blood. This virus can lead to a range of health issues, including acute and chronic liver diseases, and can be particularly severe, leading to liver cirrhosis and hepatocellular carcinoma.

HBV is known for its capacity to survive outside the body for an extended period, making blood exposure a significant risk factor for transmission. Unlike some other viruses, HBV can be transmitted through activities such as needle sharing, unprotected sexual contact, and from mother to infant during childbirth.

In contrast, Hepatitis A Virus (HAV) is primarily transmitted through the fecal-oral route and does not cause chronic liver disease. Hepatitis C Virus (HCV), while also causing liver infection and transmitted through blood, is not characterized as having the same prevalence of transmission potential as HBV. Human Immunodeficiency Virus (HIV) is associated with a different infection that compromises the immune system rather than specifically causing liver disease. Thus, HBV is recognized for its direct relationship with liver infection through blood exposure.
