In 2017, the Sierra Leone Ebola Database (SLED) Project was established and funded by the U.S. Center for Disease Control and Prevention (CDC), and implemented by eHealth Africa (eHA), in collaboration with Sierra Leone’s Ministry of Health and Sanitation (MoHS) and CONCERN Worldwide.

The goal of the SLED project is to collect, link, and analyze data recorded during the Ebola epidemic in Sierra Leone. The project also aims to use the database to reunite families with graves of loved ones lost during the epidemic through a family reunification program.

Project Details:

After the 2014 Ebola Virus Disease (EVD) outbreak in Sierra Leone, there was a need for an accurate database that stored data about the outbreak. The data could be used for a variety of reasons particularly for research for future epidemiology challenges on prevention and response to EVD outbreaks.

SLED Database is made up of five sources of data categories from data contributors. The five data categories are:

Hot Line alerts (117, Kambia, and Kailahun hotlines) Viral Hemorrhagic Fever (VHF) system data - Laboratory testing database, consolidated daily laboratory results - Burial records from multiple sources -

Ebola Treatment Unit (ETU) and Ebola Holding Center (EHC) records

With accurate and verifiable data in place via SLED, family members can now get the appropriate information for locating the graves of their deceased loved ones through the family reunification program. The family reunification program was started in 2018, and the data managers work in close collaboration with CONCERN Worldwide to ensure that search requests from the public are received (via secure File Transfer Protocol (sFTP) and gravesite location matches are made, when possible.

eHA's role

  • Facilitate the data acquiring and storing processes.

  • Provide technical oversight to the family reunification program.

  • Hired and trained data managers to be responsible for the day-to-day data activities that facilitate proper data storage, security, and linkage capacity.
