Nebraska首次报告奶牛禽流感病例;目前17个州有病毒,但消毒牛奶是安全的。 Nebraska reports first dairy cow bird flu case; virus now in 17 states, but pasteurized milk is safe.

Nebraska证实,它第一次在奶牛群中出现禽流感病例,标志着病毒自2024年3月以来蔓延到17个州。 Nebraska has confirmed its first case of bird flu in a dairy cattle herd, marking the virus's spread to 17 states since March 2024. H5N1菌株类似于加利福尼亚的H5N1菌株,通过强制性牛奶测试在内布拉斯加州中部检测到。 The H5N1 strain, similar to one in California, was detected in central Nebraska through mandatory milk testing. 受感染的奶牛表现出诸如牛奶产量下降、食欲下降和鼻腔排泄等症状,但大多数恢复时死亡率极低。 Infected cows show symptoms like reduced milk production, decreased appetite, and nasal discharge, but most recover with minimal mortality. 受到影响的牛群被隔离,官员们强调,由于在消毒过程中病毒不活跃,消毒牛奶是安全的。 The affected herd is quarantined, and officials stress that pasteurized milk is safe due to virus inactivation during pasteurization. 虽然人类病例很少,而且大多与受感染动物直接接触有关,但一般公众的风险仍然很低。 While human cases are rare and mostly linked to direct contact with infected animals, the general public remains at low risk. USDA和内布拉斯加官员继续调查,敦促奶牛农场加强生物安保。 The USDA and Nebraska officials continue investigations and urge dairy farms to strengthen biosecurity.
