Which highly contagious virus is known for causing vomiting and diarrhea?

Norovirus is recognized as the highly contagious virus responsible for causing acute gastroenteritis, which leads to symptoms such as vomiting and diarrhea. It is often spread through contaminated food or water, as well as through direct contact with an infected person or contaminated surfaces. The virus is particularly notorious for outbreaks in settings like cruise ships, schools, and nursing homes, where close proximity facilitates its rapid spread.

Other viruses listed in the choices have different effects. Influenza primarily affects the respiratory system and is associated with symptoms like fever, cough, and body aches. Hepatitis viruses, such as Hepatitis A, B, and C, primarily impact the liver and can lead to symptoms like jaundice and liver dysfunction, although some types can also cause gastrointestinal distress but not as distinctly as norovirus. Rhinovirus is most commonly linked to the common cold, impacting the upper respiratory tract, and does not typically cause the severe digestive symptoms that norovirus is known for. Thus, norovirus is specifically identifiable for its role in gastrointestinal outbreaks, confirming it as the correct answer.
