Avian migration is a global phenomenon that transcends geographical boundaries. These migratory birds serve as unwitting carriers of diverse Gammacoronaviruses (γ-CoVs) and Deltacoronaviruses (δ-CoVs). While recombination events have been documented among γ-CoVs in avian species and β-CoVs in mammals, evidence for recombination between CoVs of distinct genera remains limited. This minireview examines the prevalence of CoVs in both domestic waterfowl (ducks and geese) and wild bird populations inhabiting various regions. We investigate the dissemination patterns of γ-CoVs and δ-CoVs among these populations, highlighting their shared characteristics. Furthermore, the review explores the intricate web of cross-species transmission of δ-CoVs from wild birds to mammals, with a particular focus on pigs. Understanding the distinct features of CoVs harbored by waterfowl and wild birds and their potential for cross-species transmission is crucial for preparedness and response to future CoV epidemics.
禽类迁徙是一种跨越地理边界的全球性现象。这些候鸟不经意间成为了多种γ 冠状病毒（γ-CoVs）和 δ 冠状病毒（δ-CoVs）的携带者。虽然已经记录了在禽类的γ-CoVs 与哺乳动物的β-CoVs 之间存在重组事件，但不同属的 CoVs 之间发生重组的证据仍然有限。这篇小型综述考察了在不同地区栖息的家养水禽（鸭和鹅）和野生鸟类种群中 CoVs 的流行情况。我们研究了 γ-CoVs 和 δ-CoVs 在这些种群中的传播模式，强调了它们的共同特征。此外，该综述还探讨了 δ-CoVs 从野生鸟类向哺乳动物的跨物种传播的复杂网络，特别关注猪。了解水禽和野生鸟类所携带的 CoVs 的独特特征及其跨物种传播的潜力，对于为未来的 CoV 流行做好准备和应对至关重要。
