Alberta Investigates Cyclospora Cases Amid US Outbreak

Health authorities in Alberta are actively investigating an increase in cyclosporiasis cases, a parasitic illness that can lead to severe diarrhea. Since early May, six individuals have developed symptoms and tested positive for the infection. While four of these cases are associated with recent travel to Mexico, none have been linked to travel within the United States. Authorities have confirmed no hospitalizations or deaths related to these cases.

Despite the uptick in Alberta, no direct link has been established between these illnesses and a significant outbreak currently affecting the United States, which has seen thousands of confirmed and suspected cases. Investigations are ongoing, focusing on travel histories and potential food exposures. Experts suggest that unusual weather patterns in regions like Mexico could contribute to such outbreaks by affecting water sanitation and agricultural practices.

Cyclosporiasis symptoms typically include watery diarrhea, stomach cramps, and a mild fever, with recovery sometimes taking weeks to months. Vulnerable populations, including the very young, elderly, and immunocompromised, are at higher risk. Previous outbreaks in Canada have been traced to imported produce, with leafy greens, berries, and herbs often implicated. Washing produce may not fully eliminate the risk, as the parasite can adhere strongly to plant surfaces. Cooking produce is recommended, and choosing locally-grown options may reduce exposure risk due to higher water sanitation standards in Canada.
