跟进：新墨西哥州多纳安娜县确认两例新世界螺旋蝇病例 州畜牧局扩大监测诱捕

新墨西哥州多纳安娜县拉斯克鲁塞斯市——新墨西哥州动物卫生官员10月27日确认，该县出现两例新世界螺旋蝇病例：一例是在新墨西哥州立大学拉斯克鲁塞斯校区的一只羊身上发现，另一例是在校外一处地点的一头牛身上发现。州与联邦官员正在受影响地点周边扩大监测和诱捕工作，以确定这种害虫是否已扩散到受感染动物之外，诱捕器已布设在大学校园内。新世界螺旋蝇是一种以活体动物伤口为食的寄生蝇，幼虫会侵害牲畜伤口，可造成严重伤害甚至死亡，对畜牧业构成威胁。州兽医、州畜牧局的萨曼莎·霍莱克博士表示，早期发现对控制新世界螺旋蝇、保护动物健康至关重要，她呼吁校园社区了解警示迹象，发现可疑伤口或虫害及时报告。官员提醒养殖户和动物主人检查牲畜伤口，发现异常及时向州畜牧局报告，不要自行处理疑似病例。监测范围扩大后，相关部门将根据诱捕和检查结果判断是否需要采取进一步防控措施。目前公布的信息未说明两例病例的具体发现日期，也未公布除上述两只动物外是否还有其他感染，相关调查仍在进行中。

Follow-Up: Two New World Screwworm Cases Confirmed in Doña Ana County, New Mexico; Livestock Board Expands Surveillance and Trapping

Las Cruces, Doña Ana County, New Mexico — New Mexico animal health officials confirmed on October 27 two cases of New World screwworm in the county: one in a sheep on the New Mexico State University campus in Las Cruces, and one in a cow at an off-campus location. State and federal officials are expanding surveillance and fly-trapping efforts around the affected locations to determine whether the pest has spread beyond the infected animals, and fly traps have been placed on the university campus. The New World screwworm is a parasitic fly whose larvae feed on the wounds of living animals; infestations can seriously injure or kill livestock and pose a threat to the ranching industry. Dr. Samantha Holeck, the state veterinarian with the New Mexico Livestock Board, said early detection is critical to containing the screwworm and protecting animal health, and urged the campus community to know the warning signs and report suspicious wounds or infestations promptly. Officials are reminding ranchers and animal owners to check livestock wounds and report abnormalities to the Livestock Board rather than treating suspected cases themselves. Authorities will decide on further control measures based on trapping and inspection results. The information released so far does not state the exact dates the two cases were found or whether any animals beyond the two are infected; the investigation is ongoing.
