(JNS) The U.S. Centers for Disease Control and Prevention has reported that the current measles outbreak in the United States is the worst in over 25 years, as the City of New York closed another yeshiva in Brooklyn due to failure to vaccinate students.

According to a report on Monday, 41 new cases of measles have been confirmed. Twenty-eight states have now been infected, with 1,022 cases reported from January 1 to June 6, including 330 cases in New York State outside Manhattan, and 262 cases in Rockland County alone.

An additional 588 confirmed cases have been reported in New York City since September 2018, with the city ordering the vaccination of all Williamsburg and Borough Park residents under the age of 19.

Health officials have argued that low vaccination rates are to blame for the current outbreak, and New York City has ordered the closure of 10 Orthodox Jewish schools due to failure to comply with city vaccination orders.
