Red cross 400 cholera first aid points

Sierra Leone Red Cross established 400 cholera first aid posts in rural communities, treating 95% of people with diarrhoea in their communities. Calling the volunteers provided daily data needed for the epidemic response. An idea was born: we need community based surveillance to inform operations and response.

The first CBS pilot

The first CBS pilot in Petit Goave and Grand Goave, Haiti: Community based volunteers are trained to provide first aid (rehydration) to people with acute watery diarrhea, and equipped with basic mobile phones to detect and report acute watery diarrhea cases by SMS. Several cholera outbreaks where detected and responded to throughout the project period, thus strengthening our belief in the CBS methodology: we had a proof of concept.

Ebola outbreak hit West Africa

When the Ebola outbreak hit West Africa in 2014 it became even more evident that a functional surveillance system that extended beyond health clinics, and that engaged communities to be part of the solution to stop the spread of disease was crucial. Since disease outbreaks start and stop in communities, the most acute need was to identify, isolate and treat sick people as early as possible.

Setting up an integrated CBS project in 3 districts

Sierra Leone Red Cross and the IFRC set up an integrated CBS project in 3 districts, aiming at early detection of suspected Ebola, Measles, and Cholera, in addition to floods and wild fire. Integrated programs may have bigger positive impact than only addressing one stand-alone risk. More than 2200 volunteers contributed to the CBS system - demonstrating the scale-up potential of the CBS system and the suitability of the method in addressing various community risks.
