Mapping the likelihood of introduction and spread of HPAI in Africa and Indonesia using Multicriteria Decision Modelling
Spatial analysis of the distribution of disease risk and its visual presentation through risk maps can be used to inform the design of animal disease surveillance resulting in more cost-effective strategies. It is suitable for application in the context of HPAI H5N1 in Africa and Indonesia where the...
