In this case study, we describe an outbreak of highly pathogenic avian influenza (HPAI) virus subtype H7N3 in an ecological reserve in Chiapas, Mexico, affecting captive and wild birds. The virus was detected mainly in plain chachalacas displaying respiratory and gastrointestinal clinical signs and death within 24 hours. Mortality in white-fronted parrots and a clay-colored thrush was also recorded. We describe control strategies implemented to prevent virus dissemination and active surveillance within the risk area. Phylogenetic analysis revealed that the HPAI H7N3 virus detected in affected birds shared a close genetic relationship with Mexican H7N3 isolates from 2012.
在本案例研究中，我们描述了墨西哥恰帕斯州一个生态保护区内高致病性禽流感（HPAI）病毒H7N3亚型的一次暴发，此次暴发影响了圈养鸟类和野生鸟类。该病毒主要在出现呼吸道和胃肠道临床症状并在24小时内死亡的纯色冠雉中被检测到。白额鹦鹉和一只褐胸鸫的死亡情况也有记录。我们描述了为防止病毒传播和在风险区域内进行主动监测而实施的控制策略。系统发育分析表明，在受感染鸟类中检测到的HPAI H7N3病毒与2012年墨西哥的H7N3分离株具有密切的遗传关系。
