Abstract：
In May 2021, Lesotho reported its first outbreak of highly pathogenic avian influenza (HPAI) to the OIE. Samples were collected from infected poultry and the virus was confirmed by molecular tests to be of the H5N1 subtype. Full genome sequencing and phylogenetic analysis revealed that the viruses belonged to clade 2.3.4.4b and showed high identity with A/H5N1 viruses identified in Nigeria and Senegal in early 2021. The identification of A/H5N1 HPAI in Lesotho has important implications for disease management and food security in the region.
摘要：
2021年5月，莱索托向OIE报告了首次爆发高致病性禽流感（HPAI）。从受感染的家禽中收集样品，并通过分子测试确认该病毒为H5N1亚型。全基因组测序和系统发育分析显示，这些病毒属于进化枝2.3.4.4b，与2021年初在尼日利亚和塞内加尔发现的A/H5N1病毒具有高度同一性。在莱索托确定A/H5N1型高致病性禽流感对该地区的疾病管理和粮食安全具有重要意义。
