Rockland County’s Commissioner of Health, Dr. Patricia Schnabel Ruppert, announced Wednesday that all schools in the Village of New Square are now required to keep students who are un-vaccinated or under-vaccinated against the disease home until 21 days have passed since the last case of measles is confirmed in the county.

A total of 15 schools in the county are now impacted by the new requirement, Ruppert said. That is up from 10 schools affected earlier.
