Oakland County health officials have confirmed a case of hepatitis A at a restaurant in Novi.

Guests who ate at a Red Lobster in the 27700 block of Novi Road between Jan. 14 – Feb. 14 may have been exposed to the liver infection since an employee was diagnosed as having contracted it, the Oakland County Health Division reported Friday.

“Vaccination can prevent the disease if given within 14 days after potential exposure,” said Kathy Forzley, director of health and human services for Oakland County. “If you have eaten at this location during these dates and have not been vaccinated for hepatitis A or have a sudden onset of any symptoms, contact your doctor.”

Symptoms can include sudden abdominal pain, diarrhea, nausea, headache, dark urine, and/or vomiting often followed by yellowing of the skin and eyes. Symptoms can appear from 14-50 days after exposure, but average about one month, health officials said.
