Analysis of surveillance and prevention plan for African Swine Fever in Italy in 2020.

ABSTRACT

BACKGROUND: African Swine Fever (ASF) is a challenge for pig health worldwide. The disease has spread to multiple countries on five continents. ASF-free countries need to apply effective strategies to prevent the introduction of infection. METHODS: Italy implemented a surveillance and prevention plan for ASF in 2020, supported by a dedicated information system. Several pillars for action have been identified passive surveillance in both domestic pigs and wild boar populations, verification of the implementation of biosecurity measures on farms and an awareness campaign for all involved stakeholders. RESULTS: There were some regional differences in the management of passive surveillance. In order to identify all critical points and apply corrective measures, regional authorities were called to carry out a gap analysis exercise in July 2020. There were an adequate number of samples collected from wild boar but the number of samples collected from domestic pigs was below the target in most regions. Furthermore, sample distribution within the country was not homogeneous. CONCLUSIONS: During the forthcoming year, some issues must be addressed in order to establish an effective early detection system in Italian ASF-free regions.
