HACKENSACK, N.J. - The Bergen County Jail in northeastern New Jersey has been quarantined after the jail diagnosed five cases of mumps among the inmate population.
The cases were clinically diagnosed, but the tests had not been confirmed as of late Tuesday afternoon, a Bergen County Sheriff's Office spokesman said.
The first case was discovered Monday but the cause is unknown, Bergen County Executive Jim Tedesco said at a Tuesday news conference.
"It cascaded after that," said Dr. Michael Hemsley, medical director of the jail.
The quarantine means that no new inmates will be accepted until the outbreak is over. Visitors and attorneys can still go to the jail but will not have direct access to the inmates.
People who would have been sent to Bergen County will instead go to another New Jersey jail in Hudson County. Additional jails may be used going forward, Tedesco said.
The five inmates were from the general population, Tedesco and Hemsley said.
If no new cases are discovered, the quarantine will end 25 days from Tuesday.
Anyone at the jail who needs a mumps vaccination will receive one, Hemsley said.
"We will do everything to ensure the safety of our staff and inmates," Tedesco said.
The Bergen County Jail has housed immigration detainees for ICE for years. Most of those detained in Bergen have pending immigration cases.

Although Bergen officials said the mumps cases were among the general population, Hudson County authorities are taking precautions with immigrant detainees. William O'Dea, a Hudson County legislator, said officials were acting on advice from a Bergen County warden to check immigrant detainees who arrived May 18 and were on the same flight as those taken to Bergen County.
"We isolated the individuals that came in on the flight so we can check them. We are examining them, isolating them until we examine them,'' O'Dea said. "So far, the ones that we have examined there have been no issues."
How is mumps transmitted?
Mumps spreads through direct contact with saliva or respiratory droplets from the mouth, nose or throat. It can be spread through:
Close quarters can make the disease more susceptible to spreading, according to the Centers for Disease Control and Prevention.
From Jan. 1 to late May, 42 states and Washington, D.C., had reported a total of 1,002 cases of mumps this year, according to the CDC.
The disease was greatly reduced once the mumps vaccine was introduced in 1989, but cases started increasing again in 2006.
