Health officials in the county say 8 children have been infected and 6 are from the same family. Their ages ranges from 6 months to 14-years-old.
None attend public school or daycare.
The county health department said it's working with the families and healthcare providers to identify locations where others may have been exposed.
The latest cases come after Rockland County instituted a 30 day ban on unvaccinated children, which was shot down in court.
In New York City, Mayor Bill de Blasio has put in place a mandatory vaccination order for 4 zip codes in Williamsburg, Brooklyn.
Many ultra-orthodox parents have refused to have their children vaccinated for measles, and the reason why may lie in a 40 page publication called 'the vaccine safety handbook.'
It was created by a group called PEACH which stands for Parents Educating and Advocating for Children's Health. It warns that the vaccine's ingredients aren't kosher and quotes a couple of noted Philadelphia rabbis.
But the head of the Orthodox Union, Mencham Genack, said it's irrelevant because vaccines aren't eaten, so kosher laws don't apply, and the final product is highly purified.
Still, ultra orthodox mothers say giving children the vaccine goes against their religious beliefs.
On Tuesday, Mayor de Blasio announced that fines would be levied on parents who refuse to vaccinate their children.
