Flesh-eating screwworms feast on humans in Mexico; human cases top 500
摘要
自2024年食肉螺旋蝇再次入侵墨西哥以来，人类感染病例持续增加。墨西哥卫生部监测报告显示，2025至2026年人类病例已超500例。本周《新兴传染病》期刊研究分析了2025年4月至2026年3月间200余例确诊病例，发现感染速度正在加快。该研究中报告6例死亡，其中至少1例直接由蝇蛆导致。螺旋蝇曾在墨西哥和美国流行，其成虫在温血动物伤口、黏膜等处产卵，幼虫孵化
Since the flesh-eating screwworm fly reinvaded Mexico in 2024, human cases of the voracious parasite have been mounting. According to a July surveillance report from Mexico's Ministry of Health, there have been over 500 human cases in 2025 and 2026. A study this week in the journal Emerging Infectious Diseases analyzed the information on over 200 confirmed cases reported between April 2025 and March 2026 and found that the infestation pace is increasing.
Among the 200 confirmed cases in the study, six deaths were reported. At least one of the deaths was directly caused by the fly's maggots, researchers in Mexico reported in the study.
The New World screwworm (NWS) fly was once endemic in Mexico—as well as the US. The flies lay hundreds of eggs in the wounds, inflamed tissue, mucous membranes, and orifices of warm-blooded creatures. The resulting maggots hatch within a day and begin ravenously feasting on the living flesh of their victims. While the fly's maggots generate ghastly, life-threatening wounds in a variety of warm-blooded species, including humans, they're particularly devastating to livestock.
