A measles outbreak has been reported in Knox County. The Ohio Department of Health says it appears to be linked to a group of people who traveled to the Philippines for disaster relief work.

"They returned to Ohio and it now appears that there was some potential spread within the community," said ODH's Brian Fowler.

He says there are currently 13 unconfirmed cases reported. Testing should be completed on Friday.

Symptoms of the measles usually appear in 7-18 days after exposure. 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.

All this comes on the heels of a large mumps outbreak in central Ohio.

"Mumps is contagious, but measles is even more contagious," said Fowler.

The vaccines for the mumps also work for the measles.

The Knox County Health Department and the Holmes County General Health District will offer a vaccination clinic for the public on Friday from 10 a.m. to noon at the Holmesville Church of Christ, 204 W. Main Street, Holmesville, Ohio.

"We encourage all residents to consult with their physician and get vaccinated to protect themselves from this highly contagious virus," said Health Commissioner Julie Miller of the Knox County Health Department.

The Centers for Disease Control recommends that all travelers be up to date on routine vaccinations while traveling to any destination.
