Four questions, about one minute. This check cannot tell you if you have Ebola. Only a laboratory test can. It tells you whether to call the health authorities and what to do while you wait.
Update : Nigeria has confirmed one imported Ebola case in Abuja. Health teams are following up everyone who was in contact. Most fevers in Nigeria are still malaria.
What does protect you: wash hands with soap and water, do not touch the blood, vomit, stool or body of a sick person, and call 6232 early.
