New Jersey officials have issued a mandatory quarantine order for members of an NBC crew that was exposed to a cameraman with Ebola after they say a voluntary 21-day isolation agreement was violated.

The order went into effect Friday night.

Officials with the state Health Department told The Associated Press the crew remains symptom-free and there is no reason for concern of exposure to the deadly virus 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 with the disease in West Africa. Mukpo is being treated in Omaha, Nebraska.

An NBC representative didn't immediately respond to a message late Friday from the AP seeking comment.
