- 美国食品药品监督管理局表示，目前由于地理位置因素，美国大多数犬类感染新大陆嗜人锥蝇的风险较低，这种害虫以牲畜的血肉为食。
- 不过，生活在动物卫生部门已确认存在嗜人锥蝇感染区域的犬只、前往过该区域或从该区域返回的犬只，以及美国边境以南部分国家的犬只，应密切监测是否出现感染迹象，比如可见的蛆虫、伤口或身体开口处散发恶臭。
- 目前，仅在得克萨斯州和新墨西哥州的特定区域检测到了新大陆嗜人锥蝇。
- 美国食品药品监督管理局授予紧急使用授权，是为了在公共卫生威胁出现且无其他替代治疗方案时，允许使用未获批的治疗药物。
- 基于现有全部数据，美国食品药品监督管理局表示，有理由相信Simparica TRIO可有效治疗新大陆嗜人锥蝇感染。
- 该药物于2020年获得美国食品药品监督管理局批准，用于治疗犬类和幼犬的犬心丝虫病、跳蚤和蜱虫感染相关病症，且仅可凭处方购买。
- 礼蓝动保去年也获得了其药物Credelio的紧急使用授权，用于治疗感染新大陆嗜人锥蝇的犬只。

- Currently, most dogs in the U.S. are at low risk of exposure to NWS, which is a flesh-eating livestock pest, due to their geographic location, the FDA said.
- However, dogs that live in, travel to, or return from areas where screwworm infestations have been identified by animal health officials, as well as certain countries south of the U.S. border, should be closely monitored for signs of infestation, such as visible maggots, foul odors in wounds or body openings, the agency said.
- At present, NWS has only been detected in specific areas of Texas and New Mexico.
- The FDA issues emergency use authorizations to allow the use of unapproved treatments during public health threats when no alternatives are available.
- Based on the totality of data available, the FDA said it is reasonable to believe that Simparica TRIO may be effective in the treatment of NWS infestations.
- The drug was approved by the FDA in 2020 for heartworm, flea and tick-related indications in dogs and puppies. It is available only by prescription.
- Elanco Animal Health also received an emergency use nod for its drug, Credelio, last year to treat dogs infected with New World screwworm.
