Omaha, Nebraska -
The third American health worker infected with Ebola in Liberia will return to the US in the next few days.
A source tells CNN Dr. Rick Sacra is expected to land at a military base in Nebraska Friday or Saturday, and receive treatment at Nebraska Medical Center's Biocontainment Unit.
It's one of only four facilities in the country equipped to care for people with dangerous and contagious diseases.
Sacra became infected with Ebola while delivering babies at a general hospital in Monrovia.
