Ebola publications: surveillance, contact tracing, laboratory
Surveillance and contact tracing
A public health surveillance system should be in place to immediately detect and report cases of illness compatible with Ebola virus disease, or any other unusual health event possibly associated with the virus. Upon detection of a possible Ebola virus disease event, a rapid response team (or equivalent) should investigate, and conduct initial controls, including systematic contact tracing.
An alert system should be in place at the following sites: health-care facilities, especially in major hospitals, major border crossings with already affected countries, including at land crossings, airports and seaports.

Contact tracing is defined as the identification and follow-up of persons who may have come into contact with a person infected with the Ebola virus. All close contacts should be monitored for 21 days following their last known exposure to the case, and be isolated if they become ill.
