The county is experiencing New York state's longest measles outbreak since the disease was declared officially eliminated from the United States in 2000. Day said only 72.9 percent of people under 18 have been vaccinated against measles in Rockland County, which has more than 300,000 residents. This month, a federal judge, citing the "unprecedented measles outbreak," denied the parents' request to let unvaccinated children return to the Waldorf School. The lawsuit said the county's order banning unvaccinated children from schools regardless of religious or medical exemptions violated their constitutional rights. The outbreak began in the Rockland area when seven unvaccinated travelers diagnosed with measles entered the county last October.
