NEW YORK (CBSNewYork/AP) – New Jersey officials have issued a mandatory quarantine order for members of an NBC crew that was exposed to a cameraman with Ebola.

The order went into effect Friday night after they say a voluntary 21-day isolation agreement was violated, WCBS 880’s Jim Smith reported.

The crew must remain confined until October 22, the end of the time frame when the Centers for Disease Control says someone exposed to Ebola would show symptoms.

The health department is not releasing specifics on the violation, but did say the rest of the crew remains symptom-free so there is no reason for concern of exposure to the community.

Citing privacy concerns, department officials wouldn’t give further details, including who violated the voluntary agreement and how the state learned of the violation.

The NBC crew included medical correspondent Nancy Snyderman, who lives in New Jersey. She was working with Ashoka Mukpo, a cameraman who was infected in West Africa. He is being treated in Nebraska.

The cameraman has worked in Liberia for the past three years and had most recently covered the outbreak for U.S. news outlets. It is unclear what his condition was Tuesday evening, according to a CBS News report.

An NBC representative told The Associated Press it fully supports the guidelines set by local health authorities.

Nancy Writebol and Dr. Kent Brantly were both infected while working at a missionary clinic outside Monrovia. Dr. Richard Sacra, fell ill just weeks after the first two. Each was returned to the United States for treatment and each has made recoveries.

Beginning Saturday, new screenings are in effect at John F. Kennedy International Airport to help prevent the spread of the deadly Ebola virus.
