The Thunder Bay District Health Unit says about 450 people were vaccinated as a precaution after a worker at a waterfront restaurant was diagnosed with hepatitis A.
The Health Unit held two vaccination clinics since April 18, and say they have not seen another case of the disease appear since the initial diagnosis.
However, officials at the Health Unit say anyone who ate at Bight Restaurant between March 23 and April 12 should continue to monitor themselves for signs of the illness, which include fever, loss of appetite, stomach pain, tiredness, nausea, vomiting, dark urine, pale stools or yellowing of the skin or eyes.
According to Health Unit officials, the liver disease is spread from person to person or through contaminated food or water. It is not spread by coughing or sneezing.
Hand hygiene is key to preventing its spread. While most people recover completely with no permanent liver damage, in rare cases it can be serious or life-threatening. Those who are immune-compromised or have liver disease are at higher risk for complications should they contract hepatitis A.
Anyone still wishing to be immunized can make an appointment for Thursday or Friday by calling 625-5900.
