As of today, 11 measles cases have been confirmed in Georgia this year. Three members of a metro Atlanta family tested positive back in May.

The department said the children were “either unvaccinated or not fully vaccinated” and it is working to identify additional close contacts.

The Georgia Department of Early Care and Learning did not release the location of the daycare where the exposures happened.

The Atlanta-based Centers for Disease Control and Prevention says if one person has measles, up to nine out of 10 people who come into close contact with that person will become infected if they are not protected.

The CDC said the best protection is vaccination.

DPH said measles spreads through the air when an infected person coughs or sneezes, and the MMR vaccine is safe and effective.
