美国联邦卫生部门正在调查一起由微观寄生虫环孢子虫引发的疫情[1]。截至周三，该暴发已确认72例患者[1]。
环孢子虫通过接触被人类粪便污染的水而污染食物，患者会出现肠道疾病症状，表现为"频繁且有时剧烈的腹泻"[1]。美国食品药品监督管理局(FDA)尚未确定与患者相关的具体产品，病例地理位置也未公开[1]。
卫生与公众服务部表示，"这是一项正在进行的调查，官员们正在合作确定该疫情群中疾病的具体原因"[1]。
此外，美国卫生部门还在追踪另一起多州疫情，该疫情与泰勒农场公司种植的冰岛生菜相关[1]。该公司上周宣布召回了在墨西哥中部种植的冰岛生菜[1]。
根据卫生部门信息，烹饪温度至少达158华氏度(70摄氏度)可杀死环孢子虫寄生虫[1]。
Federal health authorities in the United States are investigating an emerging outbreak of cyclosporiasis, a parasitic infection that causes gastrointestinal illness. As of Wednesday, health officials had confirmed 72 cases associated with the outbreak [1].
Cyclospora is a microscopic parasite that infects food through contact with water contaminated by human feces [1]. The disease manifests as intestinal illness characterized by "frequent and sometimes severe diarrhea" [1]. Cooking food to a minimum temperature of 158 degrees Fahrenheit (70 degrees Celsius) can kill the parasite [1].
The FDA has not yet identified specific products linked to affected patients, and the locations of cases have not been disclosed [1]. Officials are also tracking a separate multistate outbreak associated with iceberg lettuce grown by Taylor Fresh Foods, which announced a recall last week of lettuce cultivated in central Mexico [1].
The Department of Health and Human Services stated that "this is an ongoing investigation, and officials are collaborating to determine the specific cause of illness in this outbreak cluster" [1].
