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.
