What is hepatitis caused by which pathogen and what part of the body is infected?

Hepatitis is primarily caused by viral pathogens, including hepatitis A, B, C, D, and E viruses. These viruses primarily infect the liver, leading to inflammation and potential liver damage. Additionally, hepatitis can also be caused by non-viral factors such as alcohol, toxins, and autoimmune diseases. The liver is crucial for various metabolic functions, and its impairment can affect overall health significantly.
