Comparative epidemiological study of the spread of African swine fever in Ukraine and some Eastern European countries

African swine fever is one of the most serious threats to the world pig industry due to high infectivity and mortality rates among pigs. To date, no effective means of active prevention of the infection have been developed. The only effective method of control is passive monitoring of the spread of the pathogen among the population of domestic and wild pigs, detection of infected animals and their depopulation. The study analyzes the spread of African swine fever in Ukraine from 2012 to 2024 and compares it with the countries that share a common border – Poland, Romania, Hungary, Slovakia and Moldova. In Ukraine, the first outbreaks were recorded in 2012 in Zaporizhzhia region among domestic pigs. In total, 619 outbreaks were detected during the study period: 482 among domestic pigs and 137 among wild pigs. The largest number of outbreaks was recorded in Odesa (64), Poltava (54), Mykolaiv (52) and Kyiv (46) regions. In Eastern European countries, African swine fever was detected later: in Poland – since 2014 (1304 among domestic and 17871 among wild pigs), Romania – since 2017 (6729 and 3649, respectively), Hungary and Slovakia – since 2018 (0 and 7875; 72 and 3645). In Moldova, the first outbreak was in 2020 (39 among domestic and 45 among wild pigs). The highest total number of outbreaks was recorded in Poland (19175), mainly among wild boars (93.2%). In Hungary, all detected cases involved wild animals. The analysis revealed a statistically significant difference in the number of African swine fever outbreaks between the analyzed countries. There is also a difference in the number of outbreaks within the analyzed time period. If we analyze the number of cases since 2018, there is no statistically significant difference. Prevention and control of African swine fever are complicated by the circulation of the pathogen among wild boars, non-compliance with biosecurity measures by owners of small pig farms and the movement of infected animals. Comprehensive monitoring with early detection of outbreaks and timely destruction of infected animals plays a key role.
