What are the primary causes of viral hepatitis?

• A. Excessive alcohol consumption
• B. Bacterial infections
• C. Viral infections
• D. Autoimmune diseases

Answer: (C)

Viral hepatitis primarily results from viral infections, which lead to inflammation of the liver. There are several different viruses that can cause hepatitis, with the most common being hepatitis A, B, C, D, and E. Each of these viruses has different modes of transmission and risk factors associated with them. For instance, hepatitis A is often transmitted through contaminated food or water, while hepatitis B and C are primarily spread through contact with infected bodily fluids. The viral nature of these infections distinguishes them from other potential causes of liver inflammation, such as alcohol consumption, bacterial infections, or autoimmune processes, which do not directly involve viruses. Understanding that viral infections are the main etiology helps in developing appropriate preventive measures and treatment options for hepatitis.
