Contact tracing

Contact tracing is one of the interventions that have been used to effectively control Ebola virus disease (EVD) outbreaks in Africa.

A burial team assistant interviews Ibrahim B Kallon, the brother of a man who died in a community in Freetown, Sierra Leone. Detailed information, including previous contacts of the deceased, was carefully documented during the interview.

Those in close contact with others who have EVD or who have died from EVD are at higher risk of infection, and of potentially infecting others if they begin to show symptoms. Closely watching such persons for 21 days from the last day of exposure will help that person to get care and treatment and will prevent the further transmission of the virus to others.

On this page you will find guidelines and resources for contact tracing, which are based on extensive field experience and outbreak response in Africa.
