Which virus is known to attack the liver and can lead to lifelong infection?

Hepatitis B is known to be a virus that specifically targets the liver and can lead to serious health issues, including chronic infection. This infection can persist throughout an individual's life if it becomes chronic, which is a possibility with this particular virus. Hepatitis B can lead to long-term complications, including liver cirrhosis and liver cancer, making it critical for healthcare professionals to recognize and manage effectively.

While other viruses listed, such as HIV and Hepatitis C, also pose significant health risks, Hepatitis B is particularly noted for its capacity to establish a lifelong infection in a host. Influenza, on the other hand, primarily affects the respiratory system and does not lead to chronic infection in the same manner as Hepatitis B and C. Understanding the nature of these viruses helps healthcare providers develop appropriate responses and interventions for affected individuals.
