加拿大数百只鹅在马尼托巴省南部死亡,在红河沿线社区附近以及在Winnipeg和Portage la Prairie等地区发现尸体。 Hundreds of Canada geese have died in southern Manitoba, with carcasses found near communities along the Red River and in areas like Winnipeg and Portage la Prairie. 这些死亡与H5N1禽流感病毒有关,在接受检查的726只鸟类中,有54只禽流感病毒检测呈阳性。 The deaths are linked to the H5N1 avian influenza virus, which has tested positive in 54 of 726 birds examined. 虽然该病毒对人类构成低风险,但2024年11月证实了一例国内传播病例。 While the virus poses a low risk to humans, a case of domestic transmission was confirmed in November 2024. 专家们认为,由于冬季气温变暖,鸟类密度增加,导致病毒传播,致使移徙推迟。 Experts believe delayed migration due to warmer autumn temperatures increased bird density, aiding virus spread. 寒冷的天气和粮食短缺可能导致死亡。 Cold weather and food scarcity likely contributed to the deaths. 由于死亡率仍然不同寻常,为了确定确切原因,正在出现各种死亡病例。 Necropsies are underway to determine exact causes, as the scale of mortality remains unusual.
