Speaking from Liberia on Thursday night on “The Rachel Maddow Show” on MSNBC, Dr. Snyderman said, “The good news is this young man, our colleague, was admitted to the clinic very, very early. I spoke with him today. He’s in good spirits.”

In a note to the NBC News staff, the division president, Deborah Turness, said: “We are doing everything we can to get him the best care possible. He will be flown back to the United States for treatment at a medical center that is equipped to handle Ebola patients.”

NBC said Dr. Snyderman has not shown any symptoms of the disease, nor have the other members of the NBC team.

“We are also taking all possible measures to protect our employees and the general public,” Ms. Turness told the staff in her message. “In an abundance of caution, we will fly them back on a private charter flight, and then they will place themselves under quarantine in the United States for 21 days — which is at the most conservative end of the spectrum of medical guidance.”
