A measles outbreak in central Ohio that sickened 85 children has been declared over, officials at Columbus Public Health announced Sunday.

Local health officials waited until no new cases were reported within 42 days – or two incubation periods of the measles virus – before declaring the outbreak over.

“This milestone fits the CDC’s definition of the end of an outbreak, however we still have test results pending for suspected cases,” Columbus health officials posted to Twitter on Sunday morning.

When the outbreak began, the CDC sent a small team to Columbus to assist with tracking measles cases and pinpointing how the virus was spreading.

There was not one single community or demographic of people within central Ohio that was at an increased risk of measles infections or had low vaccination rates.

Measles can spread through the air when an infected person coughs or sneezes or shares germs by touching objects or surfaces.
