A measles outbreak in central Ohio has now infected at least 82 children. Most of those impacted by the outbreak have been under the age of 5, state officials reported. Since details of the first measles cases were announced last month by Columbus Public Health, 32 children have been hospitalized.

he first four cases were in unvaccinated children with no travel history who were linked to a child care facility in Franklin County, Ohio.

Vaccination data wasn't available for four of the infected children, but all of the others were at least partially unvaccinated, having had no doses or just one dose of the two-shot measles-mumps-rubella vaccine (MMR).
