In a follow up to a story earlier today about a possible measles outbreak in Central Ohio, health officials from the Ohio Department of Health (ODH), Knox County Health Department and the Centers for Disease Control and Prevention (CDC), have confirmed an outbreak of measles in the Knox County area.
The ODH initially reported 16 confirmed cases; however this number was reduced to 14. Health authorities expect that number to rise. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page.

CAM plans to send 400 volunteers on two-week trips during the next several months. There have been four trips so far this year. Only the first trip included Amish from Knox County; however the subsequent trips have included Amish from neighboring Holmes County and elsewhere in Ohio, plus some from out-of-state. CAM has been cooperative in providing the names and contact
Measles is an acute, highly contagious respiratory disease caused by a virus that is easily spread. Symptoms of the measles usually appear in 7-21 days after exposure. Symptoms include fever, cough, runny nose, pink eye and a rash. The disease is highly contagious and can be transmitted from four days prior to the onset of the rash to four days after the onset. Anyone who is not immunized and gets exposed to the disease has a high likelihood of getting ill.
