Health officials in Quebec announced on Thursday, July 23, that reported cases of cyclosporiasis have risen to nearly four times the number recorded last year. The surge follows a continued spread of the intestinal parasite across the United States, marking a significant increase in the province’s incidence rate.
Cyclosporiasis is a parasitic infection that targets the intestinal tract, producing symptoms that include sudden, severe diarrhea, abdominal cramps, and sometimes fever. The disease is transmitted through ingestion of contaminated food or water, and outbreaks have been linked to fresh produce in previous instances. The parasite’s rapid multiplication can lead to dehydration and other complications if left untreated.
The latest figures from Quebec’s public health surveillance system show that the province is experiencing a rapid escalation that mirrors the broader North American trend. While exact case counts have not been disclosed, officials confirmed the rise represents a near quadrupling compared with the same period in the previous year. Epidemiologists note that the pattern aligns with the ongoing outbreak reported in multiple U.S. states, where health agencies have also documented heightened activity.
Provincial health authorities are monitoring the situation closely and have issued guidance for clinicians to consider cyclosporiasis in patients presenting with acute diarrheal illness, especially those with recent travel or consumption of high‑risk foods. Ongoing investigations aim to identify potential sources and transmission pathways to curb further spread. The public health response includes reinforcing food safety practices and encouraging individuals experiencing symptoms to seek medical attention promptly.
