Health authorities are currently investigating a significant increase in cyclosporiasis cases across 31 U.S. states, with a high number of infections reported in Michigan and Ohio.

衛生部門目前正在調查美國 31 個州環孢子蟲病病例顯著增加的情況，其中密西根州和俄亥俄州報告的感染人數較高。

The current outbreak is caused by Cyclospora cayetanensis, a tiny parasite spread through food or water contaminated with human waste. Common symptoms include long-term watery diarrhea, loss of appetite, and weight loss. While the CDC confirmed 843 cases and 86 hospitalizations by July 9, state data suggests the number is much higher; for example, Michigan reported about 2,640 cases, the largest outbreak in its history. However, the CDC emphasized that there is no evidence of a single nationwide source or an increase in how easily the parasite spreads.

目前的爆發是由環孢子蟲（Cyclospora cayetanensis）引起，這是一種透過受人類排泄物污染的食物或水傳播的微小寄生蟲。常見症狀包括長期水樣腹瀉、食慾不振和體重減輕。雖然美國疾病控制與預防中心（CDC）在 7 月 9 日前確認了 843 例病例和 86 例住院病例，但州政府數據顯示實際人數高得多；例如，密西根州報告了約 2,640 例病例，為其歷史上最大規模的爆發。然而，CDC 強調目前沒有證據顯示存在單一的全國性來源，或寄生蟲的傳播變得更容易。

Finding the contaminated food is difficult for several reasons. Because the parasite takes two weeks to show symptoms, patients often struggle to remember what they ate during interviews. Furthermore, the parasite cannot be grown in a laboratory, and standard chlorine disinfectants do not work against it, making it hard to identify tainted produce. In the past, outbreaks have been linked to imported fresh produce like basil, cilantro, and raspberries. Consequently, health officials recommend eating cooked vegetables or fruits with thick skins to reduce the risk.

找出受污染的食物相當困難，原因有幾點。由於寄生蟲需要兩週才會顯示症狀，患者在面談時往往難以回憶當時吃過什麼。此外，該寄生蟲無法在實驗室中培養，且標準的氯消毒劑對其無效，導致難以識別受污染的農產品。過去的爆發曾與進口新鮮農產品（如羅勒、香菜和覆盆子）相關。因此，衛生官員建議食用熟蔬菜或具有厚皮的水果以降低風險。

Recent budget and administrative changes have also affected the ability to respond to the outbreak. Experts, such as Barbara Kowalcyk from George Washington University, asserted that a $11.4 billion reduction in grants to health departments has made it harder to hire enough staff during crises. Additionally, some consultants argue that narrowing the FoodNet program's focus to only salmonella and E. coli has weakened data coordination between states. In contrast, the administration defended these changes, stating they were necessary to remove repetitive surveillance efforts.

近期的預算和行政變動也影響了應對爆發的能力。喬治華盛頓大學的 Barbara Kowalcyk 等專家指出，撥給衛生部門的資助減少了 114 億美元，導致危機期間難以聘僱足夠的人員。此外，一些顧問認為將 FoodNet 計劃的焦點縮小至僅限於沙門氏菌和大腸桿菌，削弱了各州之間的數據協調。相對地，政府則為這些變動辯護，稱其對於消除重複的監測工作是必要的。

The source of the current cyclosporiasis increase has not yet been found, and public health agencies continue to monitor the situation while advising people on dietary precautions.

目前環孢子蟲病增加的來源尚未找到，公共衛生機構將繼續監控情況，並就飲食預防措施向民眾提供建議。
