HACKENSACK, NJ – Bergen County Jail will remain under quarantine through the end of the month as officials investigate additional suspected cases of mumps among the inmates.

In an update issued Wednesday, Bergen County Sheriff Anthony Cureton said a sixth case was confirmed, prompting an extension of the quarantine until July 29.

The facility was placed under quarantine last month after officials discovered the first case.

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.

“The jail will continue to allow visitation to the current population and the Bergen County Sheriff’s Office is working with nearby correctional facilities to house incoming county inmates,” Cureton said.

Until the quarantine is over, 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.
