Abstract

African swine fever (ASF) is a highly fatal viral haemorrhagic disease affecting pigs. This study uses official surveillance data to investigate the persistence and spread of ASF in wild boar populations in Serbia from 2020 to 2024. A total of 480 ASF cases were analysed, with spatiotemporal clustering conducted via SaTScan™ and proximity analyses performed in the Quantum Geographic Information System. The yearly prevalence of ASF in wild boar rose steadily from 0.66% in 2020 to 1.47% in 2023. Seasonal trends showed a significant increase in cases during winter (68%) and spring (24%). Five distinct clusters were identified, predominantly near the borders with North Macedonia and Bulgaria, suggesting potential cross-border transmission. Proximity to major roads was significantly associated with ASF case distribution (p  0.01), while proximity to water bodies and elevation showed no consistent pattern. The findings highlight critical gaps in current passive surveillance systems, which likely underestimate ASF prevalence. The study underscores the need for enhanced surveillance in remote and wooded areas and proposes strategies to improve ASF monitoring and control in wild boar populations.Contribution: This study highlights the feasibility of cost-effective, non-invasive surveillance methods for ASF detection, offering critical insights for low-income countries where resources for intensive disease monitoring are limited. By demonstrating how environmental and anthropogenic factors drive ASF dynamics, this research provides actionable strategies for improving regional and global ASF control efforts.

2020 - 2024年塞尔维亚野猪非洲猪瘟时空分析。
非洲猪瘟(ASF)是一种影响猪的高致命性病毒性出血性疾病。本研究使用官方监测数据调查2020年至2024年塞尔维亚野猪种群中非洲猪瘟的持续存在和传播。共分析了480例ASF病例,通过SaTScan™进行时空聚类,并在量子地理信息系统中进行接近性分析。野猪ASF年患病率由2020年的0.66%稳步上升至2023年的1.47%。季节性趋势显示,冬季(68%)和春季(24%)病例显著增加。确定了五个不同的聚集性病例,主要在与北马其顿和保加利亚的边界附近,表明可能存在跨境传播。靠近主要道路与ASF病例分布显著相关(p < 0.01),而靠近水体和海拔没有一致的模式。这些发现突出了当前被动监测系统的严重缺陷,这些系统可能低估了非洲猪瘟的流行程度。该研究强调了在偏远和树木繁茂地区加强监测的必要性,并提出了在野猪种群中改善非洲猪瘟监测和控制的策略。贡献:本研究强调了非洲猪瘟检测的成本效益高、无创监测方法的可行性,为加强疾病监测资源有限的低收入国家提供了重要见解。通过展示环境和人为因素如何驱动非洲猪瘟动态,本研究为改善区域和全球非洲猪瘟控制工作提供了可行的策略。

期刊介绍: The Onderstepoort Journal of Veterinary Research, is the official publication of the Onderstepoort Veterinary Institute. While it considers submissions from any geographic region, its focus is on Africa and the infectious and parasitic diseases and disease vectors that affect livestock and wildlife on the continent.
