A parasitic infection that causes miserable bouts of “explosive” diarrhea is surging across the United States at rates that appear to be higher than this time last year. Meanwhile, public health authorities are racing to identify the source or sources driving the surge.
这种引起痛苦“喷射性”腹泻的寄生虫感染正在全美迅速蔓延，其发病率似乎比去年同一时期更高。与此同时，公共卫生当局正急于查明引发这种蔓延的来源或来源。
As of July 10, over 3,000 cases of cyclosporiasis have been reported, according to NBC News’ latest tally based on information from state health departments. Meanwhile, the U.S. Centers of Disease Control and Prevention confirmed 843 cases from 31 states had been reported to them as of July 9.

According to NBC News reporting, Michigan, New York, Ohio, Illinois and North Carolina are among the states hit hardest by the parasitic stomach bug. Rates usually increase during the warmer months in the United States, according to the CDC.
根据NBC新闻的报道，密歇根、纽约、俄亥俄、伊利诺伊和北卡罗来纳是受到这种寄生虫肠胃病毒打击最严重的州之一。据CDC称，在美国，这类病例在温暖的月份通常会增加。
The infection is caused by the Cyclospora cayetanensis parasite, which spreads through food and water contaminated with feces from an infected person, also known as the fecal-oral route.
该感染由环孢子虫（Cyclospora cayetanensis）寄生虫引起，通过受感染者粪便污染的食物和水传播，也就是所谓的粪口途径。

CDC在7月10日的更新中还称，“已知还有超过1500例病例需要进一步分析，以确认其是否为国内感染的环孢子虫病。”
The true number of people infected with cyclospora in the U.S. is likely higher than the numbers being reported “because some people recover without medical care and are not tested for cyclospora,” the CDC said.
CDC表示，美国环孢子虫感染的实际人数可能高于报告数字，“因为有些人未经医疗护理就康复了，且未接受环孢子虫检测。”
