Cyclosporiasis

Factsheet

Cyclospora is a parasite that is composed of only one cell. It is too small to be seen with the naked eye (only 8-10 microns in diameter). Its full name is Cyclospora cayetanensis. It used to be called such names as cyanobacterium-like, coccidian-like, and Cyclospora-like bodies (CLBs). Cyclospora infects the small intestine (bowel) and usually causes watery diarrhea, with an average of about 6 to 7 stools per day. Other symptoms can include loss of appetite, weight loss, bloating, increased flatus (gas), stomach cramps, nausea, vomiting, tiredness, muscle aches, and low-grade fever.


Disease Reporting

 
Health-care providers and clinical laboratories:
Health-care providers and clinical laboratories are required to report cases and suspect cases of cyclosporosis to local health departments within one working day of identification.  Cases are subject to restriction on school and day-care attendance, food handling, and patient care for the duration of any diarrhea and/or vomiting.
