　　This report presents the epidemiological analysis of African swine fever (ASF) during 2022 ba sed on the surveillance and pig population data submitted by the European Unio n (EU) affected countries and one neighbouring country. Coinciding with regulatory changes and an im portant decrease in ASF outbreaks in 2022 in the EU, the number of domestic pig samples tested as part of active surveillance decreased by 80%, while the number of samples from passive surveillance almost doubled compared with 2021. Most outbreaks among domestic pigs in the EU were detected by testing clinical suspicions (93% of outbreaks), followed by tracing activities (5%) and weekly testing of the first two dead pigs per establishment (2%). Although most of the wild boar samples came from hunted animals, the probability of detecting PCR-positive animals was much higher in wild boar found dead. The ASF outbreaks among domestic pigs in the EU decreased by 79% while a decrease of 40% in the wild boar cases was observed in comparison with 2021. This was stro ngly marked in Romania, Poland and Bulgaria, with a reduction of 50�C80% compared with 2021. In many countries, an im portant decrease in the number of pig establishments was observed, especially of small establishments with fewer than 100 pigs. The regio nal between farm incidence and proportion of pigs lost due to ASF in the EU was in general very low (average of 1%) apart from some regions in Romania. The impact of ASF on wild boar populations was variable, with a decline in wild boar abundance observed in certain countries versus a stable or even increased population after ASF introduction. This supports the negative relatio nship observed in this report between the proportion of the country with restricted zo nes due to ASF in wild boar and wild boar hunting bags.
