The worst Ebola crisis in all of history is causing European and American officials to reconsider how prepared they are to deal with the epidemic.
Last week a Spanish nurse who had treated an Ebola patient tested positive for the disease. Now some are questioning if proper precautions were followed at the hospital where the nurse worked.
While health officials have previously said there is no cause for concern of a full-blown outbreak in the U.S., they are now considering new measures at major airports.
Officials in the U.S. and Europe are working to quarantine people who may have come into contact with Ebola patients. To quarantine is to isolate someone in an effort to prevent the spread of disease. Officials hope this will prevent more people from getting sick.
