People who visited Kraft House No. 5 in Powell on Oct. 4 may have been exposed to measles, the Delaware Public Health District said as it investigates a case involving someone who visited the restaurant and was later diagnosed with the virus. The possible exposure was at the restaurant, 5 S. Liberty St., between 11 a.m. and 4 p.m. that Sunday. Health officials said there is no known continuing exposure risk outside those hours. Anyone who was there during the identified period should watch for symptoms for 21 days after the visit. Measles symptoms commonly begin with a high fever, cough, runny nose and red, watery eyes. A rash may develop three to five days after the initial symptoms and spread from the face down the body. Anyone who develops symptoms should stay home, avoid contact with other people and call a health care provider before going to a clinic or hospital, so staff can take steps to limit exposure to others. Kraft House No. 5 said its employees are vaccinated and that no staff member who worked during the identified period had reported symptoms. The restaurant said it is cooperating with the health district and following its guidance. Ohio has reported more than 200 measles cases this year, the most in the state in more than a decade, according to the Ohio Department of Health. The MMR vaccine is the best protection against measles. People unsure of their vaccination status can contact their health care provider or the Delaware Public Health District at 740-203-2040.
