To what extent are field data vital for drawing up risk maps for avian influenza viruses propagation in West Africa?

International audience. Since 2015, West Africa has experienced several introductions of highly pathogenic avian influenza viruses, with majorconsequences for the poultry industry. The intensification of the circulation of avian influenza viruses in this low-incomeregion of the world, combined with the presence of many multi-species village flocks lacking biosecurity measures,makes it more necessary than ever to set up a risk-based surveillance system to reduce costs. During previoussurveillance campaigns funded by the CEIRR program in Benin and Togo, and more recently in Mali, data on theorganization of the poultry industry in these countries were collected to produce risk maps of avian influenzaoccurrence. The production of these risk maps requires the collection of geo-referenced data, some of which are freelyavailable, while others require an understanding of the organization of the poultry industry at the national level. As partof this project, we were interested in assessing the importance of local data by looking at the extent to which theirabsence impacted the final result of the risk maps obtained. Risk maps were therefore produced using the GIS-MCDAapproach applied to 12 West African countries. For Togo, Benin, and Mali, several maps were drawn, in one case takinginto account local data and in the other excluding such data. The results show that taking local data into account has asignificant impact on the final risk maps, by changing the risk areas that should be prioritized for surveillance of avianinfluenza viruses.
