More Aid Workers Return to US for Ebola Monitoring

Two more American aid workers returned to the United States Wednesday to be monitored for Ebola.

Their return brings the total to 17 American citizens who have been flown back from Sierra Leone since Friday for observation.

They are staying near hospitals with special isolation units in Bethesda, Maryland, Atlanta, and Omaha, Nebraska. Thus far, none have tested positive.

All of the patients are connected to the unidentified American who returned last week after contracting the illness.
