密歇根州卫生官员称生菜或沙拉绿叶菜可能是环孢子虫病爆发源头Michigan Officials Say Lettuce or Salad Greens May Be Source of Cyclospora Outbreak

根据密歇根州卫生官员公布的初步调查结果，生菜或沙拉绿叶菜已被确定为该州环孢子虫病爆发的潜在源头。密歇根州首席医疗官纳塔莎·巴格达萨里安博士在声明中指出，在流行病学调查过程中，生菜作为一种共同暴露的产品，经常在患者的饮食史中被提及。这一发现为追踪传染源提供了关键的早期线索。

According to the preliminary findings announced by Michigan health officials, lettuce or salad greens have been identified as a potential source of the state's cyclosporiasis outbreak. Dr. Natasha Bagdasarian, the state's chief medical executive, noted in a statement that early epidemiological information has regularly highlighted lettuce as a common product appearing throughout the ongoing investigation.

尽管生菜被列为重点怀疑对象，但密歇根州卫生与公众服务部强调，目前的调查数据还不足以锁定具体的农产品品种、种植者或分销供应商。卫生官员同时明确表示，由于食品供应链的复杂性，目前阶段仍不能排除其他食品作为传染媒介的可能性，相关溯源工作仍在持续进行中。

However, the Michigan Department of Health and Human Services emphasized that current data remains insufficient to pinpoint the specific type of produce, the grower, or the supplier involved. Furthermore, health officials cautioned that other food items cannot be ruled out at this stage of the inquiry, as investigators continue to analyze dietary histories to trace the exact origin of the contamination.

根据密歇根州卫生官员与美国疾病控制与预防中心的数据，关于生菜或沙拉绿叶菜可能是传染源的初步发现目前仅适用于密歇根州。尽管该调查结果具有地域局限性，但这场食源性胃肠道疾病疫情在全美范围内已波及31个州，累计报告病例接近3000例。这一数据表明，该疾病已经在全美多个地区引发了广泛关注。

According to state health officials and the Centers for Disease Control and Prevention, the preliminary finding identifying lettuce or salad greens as a potential source currently applies only to Michigan. Although this specific epidemiological lead is localized, the foodborne gastrointestinal illness has established a national footprint. The outbreak has now been documented across 31 states, with the total number of reported cases nationwide nearing 3,000.

在这场全国性的环孢子虫病爆发中，密歇根州承受了最主要的疫情冲击。截至目前，该州已报告了2640例病例，占全美已知病例总数的绝大多数。虽然其他30个州也陆续发现了感染病例，但密歇根州的病例集中度远超其他地区，这也解释了为何当前的溯源调查和初步发现主要集中在该州境内。

Within this national outbreak, Michigan has borne the vast majority of the impact, accounting for the lion's share of the infections. Out of the nearly 3,000 cases recorded across the country, Michigan alone has reported 2,640 cases. While health authorities in dozens of other states continue to monitor the spread of the disease, the heavy concentration of cases in Michigan has made the state the primary focal point for the ongoing dietary investigations.

根据美国疾病控制与预防中心（CDC）公布的数据，在这场波及全美多州的环孢子虫病疫情中，目前已有86人因病情严重而住院接受治疗。由于该病主要通过受污染的食物传播，会导致患者出现剧烈的腹泻等胃肠道症状，部分病情较重或伴有脱水症状的患者需要接受临床监护和支持性治疗。

According to data provided by the Centers for Disease Control and Prevention (CDC), the national cyclosporiasis outbreak has resulted in the hospitalization of 86 people so far. The severe gastrointestinal illness, which is characterized by intense diarrhea, has required clinical intervention and hospital care for these individuals as public health agencies continue to monitor the spread of the foodborne infection across multiple states.

公共卫生专家同时指出，当前的住院人数和确诊病例数据并不能完全反映疫情的最新实时进展，数据往往存在明显的滞后性。这主要是因为环孢子虫病的潜伏期较长，患者在摄入受污染的食物后，通常需要大约一周的时间才会开始显现出相关症状。从患者发病、就医、进行实验室检测到最终向卫生部门上报，这一系列流程导致了统计数据的延迟。

Health experts have explained that the official case counts and hospitalization figures often lag behind the actual state of the outbreak. This statistical delay is primarily due to the nature of the infection, as it can take up to a week after consuming contaminated food for patients to develop noticeable symptoms. The time required for individuals to seek medical care, undergo laboratory testing, and have their cases officially reported to health departments contributes to this ongoing data lag.
