Thanks to the outbreak of the Orthodox Jewish community, 285 cases began in October last year.
In December, the Department of Health commissioned Jeshiv and childcare centers serving the Orthodox Jewish community to exclude all vaccinated students from school attendance or day care until the outbreak of the outbreak in the affected postcodes in Brooklyn.
Then, in January, one of Williamsburg riders did not respect the exclusion powers, allowing children to return to school or day care without vaccination.
Officials say that this only yeshiva is associated with more than 40 cases.
The Department of Health has since issued orders from the Commissioner for all Williamsburg Yeshivis to comply with the mandatory exclusion of non-vaccinated children or to face violations of fines and possible school closures.
"It is a public health crisis and can be quite easily stopped," said New York City Adviser Stephen Levin.
Officials say that many in Williamsburg listen to false information about the vaccine.
"We have to make sure there is good information there that is culturally sensitive, coming to the right people to make sure it is real scientific information so people know it is not a risk," said Levin. "Vaccination of your children is in the interests of them and the whole community."
Breastfeeding is a highly contagious disease and can cause pneumonia, encephalitis and in rare cases death. During the current outbreak, deaths have not occurred and only three deaths have occurred in the last two decades.
The majority of cases are children under 18 years of age and 39 cases in adults.
Before the Passover, the Health Department encourages everyone in New York, especially the Orthodox Jewish community, to obtain a measles-mumps-rubella (MMR) vaccine to prevent further spread of the virus.
Health officials say that people traveling to areas with high outbreaks, including Israel, Europe, the New York River and other United States, need to make sure they and their children are appropriately vaccinated with MMR.
