Nausea, vomiting, abdominal pain or cramps, watery or loose diarrhea, malaise (general uneasiness or discomfort), low-grade fever, and muscle pain. Signs and symptoms usually begin 12-48 hours after first exposure to the virus and last 1-3 days. Some infected people may not show any signs or symptoms, but they are still contagious and can spread the virus. The virus is highly contagious and commonly spread through food or water that is contaminated during preparation or contaminated surfaces. Can also be infected through close contact with an infected person. Cannot prevent norovirus after you are exposed but there are ways to prevent yourself from getting the infection      Wash your hands thoroughly.

Avoid contaminated food and water, including food that may have been prepared by someone who was sick. Wash fruits and vegetables before eating. Cook seafood thoroughly. Dispose of vomit and fecal matter carefully, to avoid spreading norovirus by air. Disinfect virus-contaminated areas with bleach. Stay home from school or work, especially if your job involves handling food. You may be contagious as long as three days after your symptoms end.

Avoid traveling until symptoms end. Norovirus causes inflammation of the stomach or intestines or both. This is called acute gastroenteritis. It occurs most frequently in closed and crowded environments such as hospitals, nursing homes, child care centers, schools, and cruise ships. Norovirus symptoms are developed 12-48 hours after the first exposure. The illness lasts 1-3 days and will last 4-6 days in young children, sick people, and older adults.

No specific medicine to treat people with norovirus illness. Norovirus infection cannot be treated with antibiotics because it is a viral (not a bacterial) infection. If you are under 65, you may take over-the-counter anti-diarrheal pills. Hydrate with plenty of liquids so you do not become dehydrated from diarrhea and/or vomiting.
