Hepatitis A, B, and C can cause what serious health issue?

Hepatitis A, B, and C are viral infections that primarily affect the liver and can lead to serious liver disease. This includes conditions such as hepatitis (inflammation of the liver), cirrhosis (severe scarring of the liver), and even liver cancer in chronic cases. The liver plays a crucial role in various bodily functions, including detoxification, metabolism, and the production of essential proteins. When the liver is compromised due to these infections, it can lead to significant health issues and potentially life-threatening complications.

The other options presented relate to different organ systems or types of diseases that are not directly caused by hepatitis viruses. For instance, autoimmune deficiency and kidney failure involve different pathophysiological processes. Pneumonia is an infection of the lungs, which is unrelated to the hepatitis viruses. Understanding the direct impact of hepatitis viruses on liver health is essential for recognizing the potential severity of these infections.
