The Ebola outbreak
The epidemiological data detailing the number of Ebola cases is updated by the World Health Organization (WHO).
* A probable or suspected case becomes CONFIRMED when a sample from that person tests positive for EVD in laboratory.
* A suspected case (evaluated by a clinician) or person who died from suspected EVD and had an epidemiological link to a confirmed case (but was not tested and did not have laboratory confirmation of the disease) becomes PROBABLE.
* Any person, alive or dead, who has/had Ebola symptoms and had contact with a suspected, probable or confirmed EVD case, or a dead or sick animal or with any person with unexplained bleeding or any sudden, unexplained death becomes SUSPECTED.
