About norovirus infections
Food and beverages contaminated with norovirus may not look or smell bad, but it can cause severe illnesses.

Symptoms of norovirus infection may include vomiting and/or diarrhea, nausea, muscle aches, fever, and headache, according to the Centers for Disease Control and Prevention. Symptoms typically start 12 to 48 hours after exposure and can last for one to three days. Most people recover without treatment, however some may need medical attention for dehydration.

People with norovirus infections can spread the infection easily to others. The virus can live on surfaces for long periods of time.
