Four Americans are being monitored for Ebola at the University of Nebraska Medical Center. The four individuals may have been exposed to the virus while in Sierra Leone, the hospital said in a statement on Sunday.
All four patients arrived at the hospital on Saturday and will be monitored by medical personnel for 21 days. The patients are not sick or contagious, said spokesman Taylor Wilson.
A U.S. healthcare worker that tested positive for the virus arrived at Maryland’s National Institutes of Health Friday. The worker is reportedly in serious condition.
The individuals who are under observation are four of 10 Americans who may have been exposed to the Ebola patient now in Maryland. All were flown back to the U.S. on non-commercial aircrafts.
The deadly Ebola virus has killed approximately 10,000 people in Liberia, Sierra Leone and Guinea. Thus far, only a few cases of the virus have been seen in the U.S., Britain and Spain. In each of these cases, the patients contracted the virus in West Africa.
The remaining six individuals are expected to be monitored at either Emory University Hospital or NIH. The CDC has stated that all individuals who were flown back to the United States were symptom-free.
