Geographic information systems: a useful tool to approach African swine fever surveillance management of wild pig populations 463-467
       

Summary
The epidemiological surveillance of African swine fever in wild pig populations requires the previous collection of numerous samples of biological materials for virological and serological testing from each animal that has been killed during the hunting season. The number of samples needs to demonstrate the absence of the disease at a prevalence level of 5% (and confidence level of 95%) in the area subject observed. Since the typology of the territory suitable for maintaining wild pig populations and the precise location can be identified, it is possible to pinpoint specific areas within Sardinia where organised sampling is undertaken. The results from tests are used to estimate the prevalence of the disease in the wild pig population in the place of origin. Areas were identified using the geographic information system technology with support from maps in the field. The correct localisation of seropositivity has led to the redefinition of high-risk areas for African swine fever. Results from the outbreaks and the surveillance of the wild pig population has confirmed the decreasing role of the wild boar in maintaining the disease
