(JTA) — More than 300 people in two New York State Orthodox enclaves have contracted the mumps.
The cases broke out in Monsey and New Square in Rockland County, about 25 miles from New York City, and have spread to Brooklyn and New Jersey Orthodox Jewish communities, according to The Journal News.
Most of those affected in Rockland Country are Orthodox or Chasidim; many had been vaccinated against the mumps.
The outbreak started in August in a summer camp in the Catskills for Orthodox Jewish boys. Twenty-five campers came down with the illness, the Centers for Disease Control told the newspaper.
