What is hepatitis A?

1. An infection caused by a bacteria affecting the skin

2. An infection caused by a virus that causes inflammation of the liver

3. A type of allergic reaction affecting the respiratory system

4. A form of bacterial pneumonia

The correct answer is: An infection caused by a virus that causes inflammation of the liver

Hepatitis A is an infection caused by a virus, specifically the hepatitis A virus (HAV), which leads to inflammation of the liver. This viral infection primarily spreads through the fecal-oral route, often from consuming contaminated food or water, and can result in symptoms such as fever, fatigue, nausea, and jaundice. Understanding that hepatitis A is viral rather than bacterial is crucial, as it distinguishes it from infections that may affect other parts of the body, such as the skin or the respiratory system. This understanding is emphasized by the fact that liver inflammation is a hallmark of hepatitis A, highlighting its specific impact on the liver rather than other organs.
