Columbus Public Health continues to investigate six confirmed measles cases in Franklin County, all involving young children, as health officials wrap up monitoring tied to a February airport exposure window.

According to reporting by WOSU, the six cases involve children under age 5. Health officials said five of the children were unvaccinated and one had received a single dose of the measles, mumps and rubella vaccine.
Columbus Public Health has said the cases are connected to a small number of households, and contact tracing has been underway to identify and notify people who may have been exposed. Officials described the overall risk to the broader public as low while the investigation continues.
Airport Exposure Alert
The Ohio Department of Health previously warned that travelers at John Glenn Columbus International Airport on Feb. 18, 2026, between 6 p.m. and 9 p.m. may have been exposed to measles. State officials advised people who were present during that window and are not vaccinated to follow public health guidance and monitor for symptoms through March 11, 2026.
Health officials have said vaccination significantly reduces the risk of infection and serious illness. The state reported it has worked with federal and local partners to notify potentially exposed travelers.
Hospital and Community Preparedness
Area health systems, including The Ohio State University Wexner Medical Center and Nationwide Children’s Hospital, routinely follow infection-control protocols for highly contagious diseases such as measles. Public health guidance emphasizes contacting a healthcare provider before arriving for evaluation if symptoms develop, so facilities can take appropriate precautions.
Columbus Public Health continues to share information about measles symptoms, vaccination clinics and general prevention measures through its website and community outreach.
What Residents Should Know
