Getting a foodborne illness by ingesting infected particles of feces or vomit is commonly associated with which virus?

The correct choice, Norovirus, is linked to foodborne illness primarily through the fecal-oral route, which often involves the ingestion of small particles from feces or vomit of an infected person. Norovirus is highly contagious and known for causing outbreaks in settings like cruise ships, restaurants, and schools. Its resilient nature allows it to survive on surfaces and in food, making transmission via contaminated food or water common.

Hepatitis A is also spread through the fecal-oral route but is specifically related to the consumption of contaminated food or water rather than direct contact with vomit or feces. Abscess virus is not a recognized pathogen associated with foodborne illness, and adenovirus, while it can cause gastrointestinal illness, is less commonly transmitted in this specific manner compared to Norovirus. Thus, Norovirus stands out as the primary virus linked to ingesting infected particles of feces or vomit, leading to outbreaks and foodborne illnesses.
