Fearful that New York's measles outbreak could infiltrate the federal correctional institution in Orange County, the facility has been closed to outsiders after the state health department revealed a sick child had been a visitor.

The child visited the satellite camp at the Federal Correctional Institution in Otisville on March 28. The New York Health Department notified the staff on April 3 that the child had recently been diagnosed with the illness, according to a press release.

Inmate visits at the satellite camp have been suspended since the notification. The facility houses 815 inmates, including 118 at the satellite camp, according to the Bureau of Prison's website.

“The Bureau of Prisons takes communicable diseases seriously. Infectious diseases are managed through a comprehensive approach that includes appropriate treatment, prevention, education and infection control measures,” the bureau said in a statement.

No inmates or staff members have contracted the disease. The vaccine is being offered to those who are unvaccinated.

About 200 people have come down with the disease in Rockland County and Brooklyn since October. Members of the Orthodox Jewish community have been disproportionately affected since many are unvaccinated.
