Which virus is known to cause jaundice?

1. Norovirus

2. Hepatitis A

3. Hepatitis C

4. Rotavirus

The correct answer is: Hepatitis A

Hepatitis A is known to cause jaundice because it is a viral infection that specifically targets the liver. When the liver becomes inflamed due to the virus, it can lead to a build-up of bilirubin in the bloodstream, which causes the skin and the whites of the eyes to take on a yellowish tint, a condition known as jaundice. This virus is primarily spread through consumption of contaminated food or water and can lead to symptoms such as fatigue, nausea, abdominal pain, and fever, in addition to jaundice. Understanding the implications of Hepatitis A is crucial for food safety, as outbreaks can occur in food service settings where hygiene practices are not properly followed. The other viruses listed are associated with gastrointestinal symptoms but do not typically cause jaundice. Norovirus is primarily linked with foodborne illnesses characterized by vomiting and diarrhea. Hepatitis C, while also affecting the liver, is less commonly associated with acute jaundice compared to Hepatitis A, often presenting with chronic liver conditions over time. Rotavirus primarily affects infants and young children, leading to severe diarrhea but does not cause jaundice.
