The Maine Center for Disease Control and Prevention is warning people may have been exposed to hepatitis A in two different locations in recent weeks. Hepatitis A is a contagious liver disease caused by the hepatitis A virus. It can spread through contaminated food or water. The most recent case involves a food service worker at Waterville Country Club's Nineteen 16 Restaurant in Oakland. The Maine CDC says that a worker handled food while infectious between April 26 and May 17 and that anyone who ate food from this restaurant during that time could be at risk.The CDC says there is no evidence linking this case to another case of hepatitis A reported on Tuesday in Skowhegan. In that case, a worker in the deli at the Skowhegan Walmart handled food while contagious between May 7 and 21.According to the CDC, you can prevent getting hepatitis A with a vaccine. Even people who are exposed to hepatitis A can avoid getting sick if they get the vaccine within 14 days of exposure.Symptoms of hepatitis A include: tiredness  low or no appetite  stomach pain  nausea  dark-colored urine  jaundice (yellowing of the skin and eyes)  Hepatitis A can spread from person-to-person or through contaminated food or water, especially in food prepared by a person who is infected. Symptoms begin to show 15–50 days after exposure to the virus. An infected person can spread the virus to others about two weeks before symptoms begin and lasting until one week after symptoms begin.
