The White House said Thursday it was closely monitoring a growing multistate parasite outbreak that has sickened more than 400 people as federal health officials race to identify the contaminated food behind the illnesses.

白宫周四表示，正在密切监测一场不断扩大的跨州寄生虫疫情，该疫情已导致超过400人染病，同时联邦卫生官员正加紧努力，力图查明导致这些疾病的受污染食品。

Press secretary Karoline Leavitt said the administration is working closely with the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) to trace the outbreak to its source, insisting the agencies have the resources they need despite questions about recent staffing changes.

新闻秘书卡罗琳·莱维特表示，政府正与疾病控制与预防中心（CDC）及食品药品监督管理局（FDA）密切合作，追溯此次疫情的源头，并坚称各机构拥有所需资源，尽管外界对近期的人员调整存在疑问。

"We're committed to providing the CDC and the FDA with the resources that they need," Leavitt told reporters. "Most importantly, we're working to trace the outbreak back to its original source, which we are currently in the process of doing."

“我们致力于向CDC和FDA提供它们所需的资源，”莱维特对记者表示。 “最重要的是，我们正在努力追溯此次疫情的原始来源，目前这项工作正在进行中。”

The outbreak has heightened concern because investigators still have not identified the contaminated food, leaving consumers without a specific product to avoid as federal and state officials work to trace the illnesses through patient interviews and food supply records.

此次疫情已引发高度担忧，因为调查人员至今仍未确定受污染的食品，导致消费者无法避开特定产品，而联邦和州官员正通过对患者的访谈和食品供应链记录来追踪疫情源头。

The White House comments came a day after the CDC warned it is investigating a large cyclosporiasis outbreak that has sickened more than 400 people in Michigan, Ohio, Kentucky and West Virginia. The agency said the actual number of illnesses is likely much higher because many infected people never seek testing or medical care.

白宫作出上述表态的前一天，CDC警告称，其正在调查一场大规模的环孢子虫病疫情，该疫情已导致密歇根州、俄亥俄州、肯塔基州和西弗吉尼亚州超过400人染病。 该机构表示，实际患病人数很可能远高于此，因为许多感染者从未接受检测或就医。

The CDC said the outbreak appears to have accelerated since May, and it is simultaneously investigating several additional clusters of cyclospora infections across the country. Public health officials are interviewing patients about everything they ate in the two weeks before becoming sick as they work to pinpoint the source.

CDC表示，自5月以来，疫情似乎呈加速蔓延趋势，同时该机构还在同步调查全美数起其他环孢子虫感染聚集性病例。 公共卫生官员正对患者展开访谈，了解他们在发病前两周内所食用的所有食物，以努力确定感染源。

Although investigators have not linked the outbreak to a specific food, cyclospora infections have historically been associated with fresh produce, including leafy greens, herbs and berries. Officials say identifying the contaminated item remains the investigation's top priority.

尽管调查人员尚未将此次疫情与某种特定食品关联起来，但环孢子虫感染历来与新鲜农产品有关，包括叶菜类蔬菜、香草和浆果。 官员表示，查明受污染食品仍是此次调查的首要任务。

Cyclospora is not typically life-threatening, but the CDC warns some people can become seriously ill and require hospitalization.

环孢子虫通常不会危及生命，但CDC警告称，部分人可能出现重症，需要住院治疗。

Symptoms generally begin about a week after exposure and can include prolonged watery diarrhea, fatigue, loss of appetite, stomach cramps and weight loss. Without treatment, the illness can last for weeks or even longer.

症状通常在接触病原体后约一周开始出现，可能包括持续性水样腹泻、疲劳、食欲不振、腹部绞痛和体重减轻。 如不及时治疗，病情可持续数周甚至更长时间。

The CDC is urging consumers to wash fresh produce thoroughly under running water, cook food when possible and to stay hydrated if symptoms develop. It also said to contact a healthcare provider if diarrhea persists.

CDC呼吁消费者在流水下彻底清洗新鲜农产品，尽可能将食物做熟，如出现症状则应注意补充水分。 该机构还表示，如腹泻持续不退，应去看医生。

Because routine stool tests do not always screen for cyclospora, officials say patients may need to specifically request testing for the parasite.

由于常规粪便检测不一定都会筛查环孢子虫，官员表示，患者可能需要主动要求进行针对该寄生虫的检测。
