African Swine Fever Virus (ASFV) genotype II dominates outbreaks in Tanzania's Southern Highlands, continuing to persist as the dominant strain over a decade after its first incursion in 2010. A total of 205 samples from 120 holdings were collected, with 21 confirmed ASFV-positive animals from 14 holdings. Molecular analysis revealed genetic uniformity among isolates, all clustering within ASFV genotype II. Poor biosecurity measures, such as feeding of untreated swill (80% of holdings) and lack of restrictions on visitors (90% of holdings), were identified as risk factors. Additionally, co-infection with porcine circovirus-2 (PCV-2) further complicates disease management. This study underscores the urgent need for enhanced biosecurity and farmer education to mitigate ASFV outbreaks in endemic regions.
非洲猪瘟病毒（ASFV）基因型II在坦桑尼亚南部高地的疫情中占主导地位，自2010年首次入侵后的十多年里，一直作为优势毒株持续存在。共从120个养殖场采集了205份样本，其中14个养殖场的21只动物经确认感染ASFV呈阳性。分子分析显示，分离株之间存在基因一致性，均聚集在ASFV基因型II内。未采取良好的生物安全措施，如投喂未经处理的泔水（80%的养殖场）以及对访客缺乏限制（90%的养殖场），被确定为风险因素。此外，与猪圆环病毒2型（PCV - 2）的共同感染使疾病管理更加复杂。本研究强调，迫切需要加强生物安全措施并对农民进行教育，以减轻地方病流行地区的ASFV疫情。
