Over 600 people attended shot clinics put on by the Kane County, Illinois, Department of Health after an employee at a Houlihan’s Restaurant was diagnosed with a hepatitis A infection, according to a story at Chicago’s ABC7 Web site. According to the story, The Kane County Health Department is offering the immune globulin shots for free to anyone who ate at the restaurant between January Eighth and the 19th.

People who ate at the restaurant should know that preventive measures are only effective during the two weeks after exposure to the hepatitis A virus. If the Immune globulin is not administered during the first two weeks after exposure, symptoms of hepatitis A food poisoning such as nausea, fever, and malaise will appear. Children can sometimes be infected and exhibit no symptoms, while adults, especially those 50 and older, can suffer severe complications of hepatitis A infection, including liver failure.
