This SSHAP Case Study explores the effective implementation of a community health worker (CHW) programme during the Ebola Virus Disease (EVD) epidemic within a collapsed health system in Port Loko district, Sierra Leone. Fear, misinformation, and distrust meant that a comprehensive community-based response was needed to support effective disease screening and referral to Ebola treatment facilities. Partners in Health (PIH), a health-care non-governmental organisation (NGO) founded in the USA, delivered a CHW programme that provided 250,000 people affected by Ebola in Port Loko district with health system services and linkages required to combat Ebola.
