A U.S. citizen working with a humanitarian organization in Congo has tested positive for the Ebola virus, the U.S. Centers for Disease Control and Prevention announced on Friday, as the Central African nation grapples with a rapidly expanding outbreak.
The CDC confirmed it is collaborating with the individual's employer, various U.S. agencies, public health authorities, and Congolese partners to prevent further transmission and identify close contacts. No additional details were immediately provided.
