Analiza przebiegu epizootii afrykańskiego pomoru świń w zachodniej Polsce

African swine fever (ASF), remains serious epidemiologic and economic concern in pig industry in Europe and Asia. The true rates of ASF spread in the individual countries, affected by this disease, are different from the theoretical scenarios. The most unpredictable factor, which is also crucial in the new episodes of ASF in wild boar observed in the areas thus far free from this disease, is human activity. These areas could be located several to even hundred kilometers from the current region of ASF occurrence in wild boar. An example may be represented by the occurrence of ASF cases in wild boar around Warsaw area in 2017, as well as in western Poland in autumn 2019. Therefore ASF may spread in wild boar population not only in a low, “natural” way, at a rate of 1–2 km per month, but also by human-mediated transfer of the virus at a rate of dozens or hundreds of kilometers. The administrative measures introduced by the Chief Veterinary Officer and the representatives of Veterinary Inspection in Poland, aimed at limiting further ASF expansion in wild boar to northern, western and southern regions. Further scenario for ASF spreading in wild boar and pig population will depend on joint, consistent and effective actions and collaboration between the Veterinary Inspection, hunters and pig producers in Poland.
