HACKENSACK, NJ – Bergen County Jail was placed under quarantine Tuesday as officials investigate suspected cases of mumps among the inmates.

During a press conference Tuesday evening, County Executive Jim Tedesco said the first case was discovered a day earlier at the facility 

According to the county sheriff’s office, they believe five inmates have mumps but they are waiting for tests to confirm the diagnosis. Symptoms of mumps include swollen glands, fatigue and headaches.

Tedesco also said all inmates and staff are being screened and officials will monitor everyone to determine if further testing is needed. Also, officials ordered 1,000 doses of the MMR vaccine for jail staff and inmates.

If no new cases are discovered, officials said the quarantine will be over by July 6.

Until then, no additional inmates will be accepted at the jail and inmates who would have been sent to the facility will instead go to Hudson County Jail, according to the county executive.

Attorneys and visitors can still go to the jail, but they won’t be given direct access to the inmates, he said.
