Abstract

Vampire bat-transmitted rabies has recently become the leading cause of rabies mortality in both humans and livestock in Latin America. Evaluating risk of transmission from bats to other animal species has thus become a priority in the region. An integrated bat-rabies dynamic modeling framework quantifying spillover risk to cattle farms was developed. The model is spatially explicit, and is calibrated to the state of São Paulo, using real roost and farm locations. Roosts and farms characteristics, as well as environmental data through ecological niche model, are used to modulate rabies transmission. Interventions in roosts (such as culling or vaccination) and in farms (vaccination) where considered as control strategies implemented to reduce risk. Both interventions significantly reduce the number of outbreaks in farms and disease spread (based on distance from source), with control in roosts being a significantly better intervention. High risk areas where also identified, which can support ongoing programs, leading to more effective control interventions.
