Peste des petits ruminants is a highly contagious viral disease of small ruminants, today spread throughout Africa, Asia and Middle-East. With recent spread of the disease towards Southern Africa, South Africa is put at risk. In a PPR-free country so where data is unavai lablc, risk analysis can be performed by spatial Multi Criteria Occision Analysis. We applied this method combining scientific knowledge and expert opinion to produce suitability maps. These maps highlight the most suitable areas for PPR spread within the territory in the case where the virus would have been introduced. The output of our work aims at providing support to decide where to target control and surveillance activities. However, our model has numerous bias due to its reliance on subjective decisions. These could be limited with the incorporation of more precise geographical data when later available; letting the opportunity to improve accuracy of suitability maps in a near future. |
