Sri Lankan cassava mosaic virus was first detected in Southeast Asia in 2015. Surveillance and a survey of cassava seed networks in Vietnam and Cambodia were conducted. This resulted in two publications integrating this information to model the combined effects on risk of virus spread. Impact network analysis was used to combine environmental risk factors, seed network data, and surveillance data to generate risk maps. This identifies key areas for disease surveillance, predicts likely spread pathways, and identifies areas for clean seed interventions. The model can incorporate updated data to recalibrate predictions in real time.
