Toronto public health officials say the number of cases of a diarrhea-causing parasite in the city is “on par with seasonal trends” following an outbreak in Michigan.
“There is currently no indication that Toronto is experiencing an unusual increase in cases,” Toronto health officials told CTV News in a statement.
Cyclospora is a microscopic parasite spread through fecal contamination of food or water.
Last week, public health officials in Michigan reported an outbreak that infected more than 170 people at the time. As of Thursday, the number of cases climbed to 1,251. No clear source of the outbreak has been identified.
Toronto Public Health confirmed 35 cases of Cyclospora have been reported in Toronto since May, with cases occurring in May and June. No cases were reported before May.
People can become infected with the parasite by consuming contaminated food or water. It is most commonly linked to raw fresh produce.
Common symptoms can include “watery” diarrhea, nausea, stomach cramps, bloating and fatigue, and are typically experienced between two to 14 days after consumption.
Person-to-person transmission is unlikely, according to health officials, as the organism requires time outside the body to undergo a transformation after being released in feces.
“Anyone experiencing symptoms of cyclosporiasis, particularly after international travel or consuming raw produce, should contact their health care provider for guidance and support.” said Toronto Health officals.
