美国正面临有记录以来最大规模的环孢子虫病疫情[2]。美国疾病控制与预防中心已确认4,173例实验室确诊的国内病例，另有7,400例正在调查，总计超过11,500人疑似患病[2]。
疫情已扩展至九个州，包括印第安纳州、肯塔基州、密歇根州、俄亥俄州、西弗吉尼亚州、伊利诺伊州、俄克拉荷马州、宾夕法尼亚州，以及堪萨斯州[2]。此外，美国全国共有41个州报告环孢子虫病病例[2]。
疫情与餐饮供应链密切相关。Taco Bell餐厅供应的冰山莴苣与前五个州的病例相关联[2]。该莴苣来自单一供应商Taylor Farms de Mexico公司，该公司已发布自愿召回[2]。食品药品监督管理局还在调查72例单独的环孢子虫病病例[2]。
A parasitic infection outbreak has spread across the United States, with the epidemic now linked to nine states. [2] The disease, cyclosporiasis, has affected more than 11,500 people, according to ongoing investigations. [2]
The Centers for Disease Control and Prevention (CDC) has confirmed 4,173 laboratory-confirmed domestic cases, while an additional 7,400 cases remain under investigation. [2] Beyond the nine affected states—Indiana, Kentucky, Michigan, Ohio, West Virginia, Illinois, Oklahoma, Pennsylvania, and Kansas—the CDC has documented cyclosporiasis cases across 41 states nationwide.

The outbreak has been traced to contaminated iceberg lettuce supplied to Taco Bell restaurants. [2] The lettuce originated from a single supplier, Taylor Farms de Mexico, which has issued a voluntary recall of its products. [2] The contaminated produce has been linked to cases in five states. [2]
Separately, the Food and Drug Administration is investigating an additional 72 cyclosporiasis cases. [2] This marks the largest recorded cyclosporiasis outbreak in the United States. [2]
