据美国食品安全新闻网消息，自6月美国亚特兰大州首次发现环孢子虫病以来，环孢子虫疫情在美国迅速蔓延，目前已扩大至20个州，近600人患病。
美国FDA与州流行病学专家分别对疫情展开了调查，调查发现墨西哥泰勒农场与两个州的疫情相关联。其他州的疫情是否也与此有关有待进一步调查。目前尚无死亡病例。
部分原文报道如下：
In the 52 days since the federal Centers for Disease Control and Prevention （CDC） in Atlanta first announced an outbreak of the single-celled parasite known as Cyclospora cayetanesis.
But the question that remains unanswered in 8th week of the outbreak asked by the CDC itself is: "…whether this conclusion applies to, or helps explain, the increase in ill persons with cyclosporiasis in other states." In other words, CDC and the states involved are officially stumped, but the investigation continues and so do the case count updates. It is not yet clear whether health officials are dealing with one big outbreak or several smaller ones.
