What is Norovirus?
Norovirus, commonly referred to as the stomach flu, causes more than 20 million cases of gastroenteritis every year. It is highly contagious and spreads quickly. It usually causes 1 to 3 days of acute nausea, vomiting and diarrhea. Norovirus can be transmitted by touching contaminated surfaces, consuming contaminated food or water or by coming into contact with infected individuals. Norovirus particles can survive on hard surfaces like countertops and doorknobs for days or weeks. Preventing the spread of norovirus is the best defense against it.
