A health worker in a protective suit carries equipment on October 1, 2014 at a Medecins Sans Frontieres (MSF) Ebola treatment centre in Monrovia, Liberia.
A 33-year-old American working in Liberia as a freelance cameraman for NBC News has been infected with Ebola and will be flown back to the United States, the network said Thursday.
"The freelancer came down with symptoms on Wednesday, feeling tired and achy. As part of a routine temperature check, he discovered he was running a slight fever," said NBC's website.
"He immediately quarantined himself and sought medical advice," NBC added.
The man, who was only hired on Tuesday, went to a Medecins Sans Frontieres (MSF) treatment centre to be tested on Thursday, and the positive result came back just under 12 hours later.
He was a second cameraman for NBC News chief medical editor and correspondent Dr. Nancy Snyderman, who is reporting on assignment in Monrovia with three other NBC employees.
He is the fourth American to have contracted Ebola in Liberia. The other three were Christian missionaries who became infected in health-care settings.
The cameraman's name was not revealed, but NBC said he "has been working in Liberia on various projects for the past three years."
