Norovirus is primarily associated with which of the following symptoms?

Norovirus is primarily associated with gastrointestinal symptoms, particularly vomiting and diarrhea. This highly contagious virus typically causes acute gastroenteritis, leading to inflammation of the stomach and intestines. The rapid onset of symptoms, which can occur within 12 to 48 hours after exposure, includes both vomiting and diarrhea, sometimes leading to dehydration if the fluid loss is severe.

While other symptoms such as fever, fatigue, and in rare cases skin rash can accompany norovirus infection, they are not the hallmark indicators of the disease. The vomiting and diarrhea resulting from norovirus can significantly impact hydration and overall health, making these symptoms critical in identifying and managing the infection. Therefore, vomiting and diarrhea are the primary symptoms associated with norovirus infections, highlighting the need for proper hygiene and food safety practices to prevent outbreaks.
