Which virus is associated with adult gastroenteritis from contaminated food and water?

• A. Norwalk-like viruses
• B. Rotavirus
• C. Hepatitis C virus
• D. Coronavirus

Answer: (A)

Norwalk-like viruses, now commonly referred to as noroviruses, are a major cause of viral gastroenteritis among adults, particularly associated with outbreaks stemming from contaminated food and water. These viruses are highly contagious and can spread rapidly in crowded environments like cruises, restaurants, and nursing homes. The symptoms typically include diarrhea, vomiting, stomach cramps, and nausea, which can lead to dehydration, particularly in vulnerable populations. Unlike noroviruses, rotavirus primarily affects infants and young children, leading to severe diarrhea and dehydration, but it is not a common cause of gastroenteritis in adults. Hepatitis C virus primarily affects the liver and is associated with chronic liver disease rather than gastroenteritis. Although some coronaviruses can cause gastrointestinal symptoms, they are more widely known for respiratory infections, especially highlighted by the COVID-19 pandemic. Thus, noroviruses stand out as the primary viral agents responsible for adult gastroenteritis linked to contaminated food and water.
