Ontario has experienced 36 locally-acquired cyclosporiasis since April 1, 2018 until July 19, 2018.
Cyclosporiasis is an infection of small bowel by parasite Cyclospora cayetanenis. Symptoms are: frequent, watery diarrhea; anorexia; fatigue; abdominal cramps; nausea; and myalgia. If untreated, symptoms last 6-7 weeks and vary in intensity.
Cases are usually from travelers to endemic countries( Caribbean, South and Central America, South and East Asia) and by ingesting food or water contaminated with the parasite.
Diagnosis can be done by a simple stool test.
Treatment is Septra or Bactrim.
