What is the incubation period for cyclosporiasis?

Step 1 of 2

Cyclosporiasis is an infection caused by Cyclospora cayetanensis. It causes traveler’s diarrhea. Cyclosporiasis cases have been reported from worldwide, including, United States, Southeast Asia, Caribbean, South America, Eastern Europe, Central America, Nepal and Australia. The oocysts of this protozoan have been found in many immunocompromised individuals with no travelling history as well as in immunocompromised travelers traveling to developing countries.

Individuals raveling to the poorly developed, warm regions and immunocompromised patients are at the higher risk of contracting disease. The infection is caused mainly through ingestion of food contaminated with oocyst of C.cayetanensis. Three of the businessmen in Toronto were diagnosed with cyclosporiasis, after they came back from United States, in the year 1996. The outbreak that took place in United States was believed to have occurred after ingestion and importation of Guatemalan raspberries.
