Public health officials are urging anyone who ate at a Lloydminster restaurant to contact their local health office for a hepatitis A vaccination.

A worker at the KC Steakhouse in Lloydminster has tested positive for hepatitis A.

"Given Lloydminster is on a well-travelled route, there may be people across Alberta who have eaten at the restaurant between Nov. 20 to Nov. 28," Dr. Karen Grimsrud, deputy provincial health officer for Alberta, said in a release Thursday.

"It's important that people contact public health as soon as possible for a vaccine as it can prevent the disease."

Lloydminster is on the Saskatchewan border, east of Edmonton.

Hepatitis A is a viral infection that affects the liver. Symptoms include fever, fatigue and nausea followed by yellow jaundice.

A vaccine will offer protection from the virus if received within 14 days after contact. However, if more time has elapsed since contact with the virus, there is no preventative vaccine or medication, Grimsrud warned.
