A nurse is teaching a group of newly licensed nurses about norovirus. Which of the following statements should the nurse make?

Norovirus is primarily transmitted through contaminated food, water, surfaces, or person-to-person contact (fecal-oral route). Contaminated shellfish (oysters) and leafy greens are common vehicles. Norovirus causes vomiting and diarrhea leading to dehydration — not fluid overload. Norovirus is not transmitted by mosquitoes (which spread malaria, dengue, Zika). The incubation period is 12–48 hours, not 7 days.
