It's becoming the main cause of food borne disease in the U.S., this Norovirus, also called the Norwalk Virus, has struck Bay County twice in the past year.
Infectious diseases Dr. Ikram-Ul-Haq says the virus strikes in large groups.
"From time to time we see some outbreaks in the community. Whenever we have lots of people together, you can acquire that," he says.
The Norwalk Virus is commonly known as the "cruise ship virus” because once let loose, it's extremely contagious in close quarters, even restaurants, on a much smaller scale.
More than 50 people got sick with the virus after eating at Uncle Ernie's Bayfront Grill and Brew House and 150 people got sick after eating at Mikato Japanese Restaurant earlier this year.
"It's not fatal, but it can cause significant dehydration," Dr. Ikram-Ul-Haq says.
The virus is spread through contaminated food. More often than not, a feces particle will attach to uncooked or poorly cooked food.
"Mostly by the ingestion of the contaminant. Either water or salad or sometime people consume poorly cooked clam or oysters," adds the doctor.
The Centers for Disease Control says half of all food-related illnesses are caused by the Norwalk and more often than not food handlers are to blame for spreading the virus.
The owner of Uncle Ernie's told Newschannel Seven the Health Department found no fault of wrong doing on the part of the restaurant.
