Noroviruses explained

Norovirus is a highly contagious virus causing viral gastroenteritis in humans. It spreads mainly through the fecal-oral route, either by consuming contaminated food or water or through direct contact. Symptoms include nausea, vomiting, diarrhea, and sometimes fever, with recovery typically in two days. No medical treatment exists, but hydration and easily digestible foods are recommended. Prevention includes frequent hand washing.
