MedicineViral infection
Quick Answer
Norovirus is a highly contagious virus that causes sudden vomiting and diarrhea, often in outbreaks. It spreads easily in crowded places such as schools, cruise ships, and nursing homes.
The Full Story
Norovirus is a major cause of acute gastroenteritis worldwide. It spreads through contaminated hands, surfaces, food, water, and tiny airborne particles from vomiting. Even a small number of viral particles can infect a person, which is why outbreaks can move quickly through groups. There is no routine vaccine in widespread use yet, so prevention depends on handwashing, cleaning, and isolation of sick people.
