| Abstract | Classical Swine Fever (CSF) is an endemic viral disease in European wild boar populations causing high economic impact to the pig farming industry. Virulence is a crucial factor determining persistence in local wild boar populations. We considered shift in virulence on the time scale of recent outbreaks using an individual-based spatially-explicit model which represents knowledge on wild boar ecology and CSF virus epidemiology. Two alternative scenarios were supposed as reasonable mechanisms that shift virulence pattern: 1) evolution of pathogen's virulence and 2) selection for host resistance. With both processes we found a possible short term shift to lower virulence. Pathogen evolution, however, resulted in faster decline down to a threshold level, while host selection resulted in slower but continuous decline of virulence. Both mechanisms promoted disease persistence. |
