Abstract
We describe an outbreak of Cyclospora cayetanensis infection among Dutch participants at a scientific meeting in September 2001 in Bogor, Indonesia. Fifty percent of the investigated participants were positive for C. cayetanensis. To our knowledge, this outbreak is the first caused by C. cayetanensis among susceptible persons in a disease-endemic area.

Summary
We describe an outbreak of Cyclospora cayetanensis infection among Dutch participants at a scientific meeting in September 2001 in Bogor, Indonesia. Fifty percent of the investigated participants were positive for C. cayetanensis. To our knowledge, this outbreak is the first caused by C. cayetanensis among susceptible persons in a diseaseendemic area. After the meeting, several participants reported mild-to-severe gastrointestinal symptoms, and C. cayetanensis infection was diagnosed in 4 participants. We investigated the extent of the outbreak among participants from our institute and identified C. cayetanensis–specific symptoms. All Dutch participants stayed in this hotel during the meeting and consumed the same meals (buffet). The questionnaire was set up to collect information about gastrointestinal symptoms, duration of stay, and results of earlier fecal diagnostic examination
