Dr. Aron Hall, an epidemiologist at Centers for Disease Control and Prevention's Division of Viral Diseases, said getting norovirus is common, it is the leading cause of food borne illness and spreads easily.
"People who have the virus are more likely to spread it while they have symptoms and for three days after their symptoms stop," Hall said in a statement.
"You can get the virus by having close contact with infected people, or touching things that have the virus on them then putting your fingers in your mouth, or consuming contaminated food or drinks."
To reduce risk of contacting norovirus:
-- Wash your hands often with soap and water.
-- Rinse fruits and vegetables before preparing or eating them.
-- Disinfect contaminated surfaces.
-- Cook shellfish thoroughly.
-- Use rubber gloves if you clean up after someone who is infected.
