New York City has been hit with a record case of the measles. The outbreak even led Mayor Bill de Blasio to declare a state of emergency in pockets of Brooklyn where the disease is spreading within ultra-Orthodox communities. Those who refuse to get vaccinated could be fined.
The first case of measles was first reported in Brooklyn in September — a child caught the infectious disease on a trip to Israel, which is having its own outbreak. Since then, the outbreak has continued to gain momentum in Brooklyn and heavily Jewish areas of suburban Rockland County, where rates of vaccination have dropped despite most rabbis and other community leaders urging families to get vaccinated.
