Snyderman, now a medical correspondent for NBC, was on assignment in Monrovia, Liberia during the outbreak, when her cameraman began exhibiting symptoms of the disease. Officials at Doctors Without Borders said he tested positive for the virus, on Thursday.

Saturday’s announcement from the CDC coincides with news that a passenger from Liberia suspected of carrying the deadly virus was taken, along with his daughter, from a plane that landed in Newark from Brussels.

The man reportedly exhibited possible symptoms of Ebola during the flight. CDC workers dressed in full hazmat gear escorted the man and his daughter off the plane.

Health officials said they do not believe the pair have Ebola.

Meantime, at Texas Health Presbyterian Hospital in Dallas, Ebola patient Thomas Eric Duncan’s condition has gone from serious to critical.

Duncan arrived from Liberia last month when he became ill.

There are no other confirmed cases of Ebola in the U.S., but as more and more cases surface, the Obama administration is instituting stricter health guidelines in an effort to allay growing public fears.

Saturday, tough restrictions for airline passengers went into effect. Now, all passengers arriving on international flights are subject to rigorous screening.

There will also be strict rules for health professionals, as well as expanded training.
