Abstract

In 2022-2024, three outbreaks of sheeppox (SPP) were reported in the European Union. These occurred in Spain, Bulgaria, and Greece and had serious economic consequences due to animal losses and trade restrictions. Five sheeppox virus (SPPV) whole-genome sequences (WGSs) were determined from samples collected during these outbreaks and analyzed in the context of all other published WGSs. Sheeppox virus strains can be divided in two, or possibly three, main groups. The isolates from the recent outbreaks belong to clade A2, which includes strains historically circulating in the Middle East and Northern Africa. Sequence divergence was low among the isolates that caused the recent European outbreaks. These results highlight the need for more regular and dense surveillance in under-sampled areas and the use of WGS to increase the chance of pinpointing the origin of an introduction, identifying potential introduction routes, and providing insights into SPPV evolution.

2022-2024 年在西班牙、保加利亚和希腊爆发的欧洲 Sheeppox 病毒基因组序列

2022-2024 年，欧盟报告爆发了三次羊痘（SPP）疫情。这些疫情发生在西班牙、保加利亚和希腊，由于动物损失和贸易限制，造成了严重的经济后果。从这些疫情爆发期间采集的样本中确定了五种羊痘病毒（SPPV）全基因组序列（WGS），并结合所有其他已发表的 WGS 进行了分析。Sheeppox 病毒毒株可分为两大类，也可能是三大类。近期疫情中的分离株属于 A2 支系，其中包括历史上在中东和北非流行的毒株。导致最近欧洲疫情爆发的分离株之间的序列差异较小。这些结果突出表明，有必要在采样不足的地区进行更定期、更密集的监测，并使用 WGS 来增加精确定位传入来源的机会，确定潜在的传入途径，并深入了解 SPPV 的进化。

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
