美国报告,在马里兰州最近前往萨尔瓦多的一位居民中,美国第一个人类案例是食肉寄生虫“新世界螺丝虫”。 The U.S. has reported its first human case of the New World screwworm, a flesh-eating parasite, in a Maryland resident who recently traveled to El Salvador. 虽然在人类中很少见,但寄生虫主要影响牲畜。 Though rare in humans, the parasite primarily affects livestock. 病人已经康复,公共卫生风险被认为较低。 The patient has recovered, and the risk to public health is considered low. 美国以前曾在1960年代消灭过寄生虫,但它一直从南美洲向北扩散。 The U.S. had previously eradicated the parasite in the 1960s, but it has been spreading northward from South America. 预防性措施包括在得克萨斯州建造一个无菌苍蝇生产设施。 Preventative measures include building a sterile fly production facility in Texas.
