Health officials in Maine have traced a case of Hepatitis A back to a community dinner in the town of Durham. Attendees who ate at the Durham Friends Meetinghouse over the weekend of Sept. 28 have been encouraged to receive a vaccine for Hepatitis A if they have not previously been vaccinated. Approximately 100 people are believed to have attended the dinner. Those who receive vaccines within two weeks of exposure to Hepatitis A have a good chance of staving off illness. The Maine Centers for Disease Control and Prevention will hold a free vaccination clinic on Wednesday, Oct. 9, from 1 p.m. to 4 p.m. at the Durham Eureka Community Center. Symptoms of Hepatitis A illness include fatigue, nausea, vomiting and abdominal pain.
