Issues with gaps in mapping
Difficulty in rapidly locating villages of Ebola cases and their contacts due to: Villages with similar names, in different chiefdoms Villages with alternate names Missing locations of recent villages and satellite villages Laura Nic Lochlainn EPIET/MSF Mobilisation of local people and technology in mapping 3

Project Aim Improve mapping within Tonkolili District by mobilising local people in order to obtain reliable geographical information to trace Ebola cases and their contacts Improve mapping within Tonkolili District by mobilising local motorcycle riders and using readily available open-access smartphone technology in order to obtain reliable geographical information to enable the tracing of contacts of Ebola cases.

1. Mobilisation of local people
Possible due to availability of Motorbike “okada” drivers Local people with GPS-enabled smartphones Added advantages All familiar with the district Motorbikes able to navigate difficult terrain No training needed for devices Ivan Gayton/MSF All self-owned by 12 of the 24 workers. No resource injection required. Laura Nic Lochlainn EPIET/MSF Mobilisation of local people and technology in mapping 6
