背景 Cyclospora cayetanensis 是一种引起胃肠炎的寄生虫。直到去年，北美记录的大多数环孢子虫病病例都是海外旅行者。 1996年，北美爆发了环孢子虫病大流行。我们调查了这次疫情。方法卫生部门向临床医生和实验室收集有关环孢子虫病病例的信息，然后将这些信息报告给疾病控制和预防中心以及加拿大卫生部。我们对与事件（例如午餐）相关的病例进行了回顾性队列研究，并试图确定相关食物的来源。 结果 20 个州、哥伦比亚特区和 2 个省共报告了 1465 例环孢子虫病病例。在这些病例中，978例（66.8％）得到实验室确诊，725例（49.5％）与5月3日至6月14日举行的55场活动有关。50场活动中肯定提供了覆盆子，并且可能在4场活动中提供了覆盆子。对于有足够数据的41场活动中的27场（65.8％），浆果的消费（带或不带其他浆果的覆盆子）与食用之间的关联环孢子虫病具有统计学意义（P
Background Cyclospora cayetanensis is a parasite that causes gastroenteritis. Until last year most of the documented cases of cyclosporiasis in North America were in overseas travelers. In 1996, a large outbreak of cyclosporiasis occurred in North America. We investigated this outbreak.Methods Health departments solicited information from clinicians and laboratories on cases of cyclosporiasis, which were then reported to the Centers for Disease Control and Prevention and to Health Canada. We conducted retrospective cohort studies for the cases associated with events (e.g., luncheons) and attempted to identify the sources of the implicated food.Results A total of 1465 cases of cyclosporiasis were reported by 20 states, the District of Columbia, and 2 provinces. Of these cases, 978 (66.8 percent) were laboratory confirmed and 725 (49.5 percent) were associated with 55 events that were held from May 3 through June 14. Raspberries were definitely served at 50 events and may have been served at 4 events, For 27 of the 41 events for which adequate data were available (65.8 percent), the associations between the consumption of berries (raspberries with or without other berries) and cyclosporiasis were statistically significant (P
