Norovirus is a leading cause of gastroenteritis, causing inflammation of the stomach and intestines. It leads to symptoms like diarrhea, vomiting, nausea, stomach cramps, and occasionally, low-grade fever
Symptoms of norovirus infection can appear suddenly, typically within 12 to 48 hours after exposure. The illness is generally self-limiting, lasting for 1 to 3 days, but severe cases may require medical attention.
