Michigan health officials reported on Thursday that cases of cyclosporiasis have reached 4,312. This figure represents an increase of 550 cases from the previous day. The Michigan Department of Health and Human Services (MDHHS) stated that 102 individuals in the state have been hospitalized due to the infection since the outbreak began on May 1.
The U.S. Centers for Disease Control and Prevention (CDC) reported that as of Wednesday, there were 1,645 laboratory-confirmed cases across 34 states and 5,100 possible cases under investigation. While the outbreak is centered in Michigan, high case counts have also been noted in Ohio and New York. No deaths have been reported nationally, though total hospitalizations across the 34 states reached 141.
Cyclosporiasis is an intestinal illness caused by a parasite, often transmitted through water or produce contaminated with feces. Symptoms typically include diarrhea and nausea. While Michigan health officials have identified lettuce as a potential source, they have not yet linked the outbreak to a specific grower, supplier, or type of produce. The Food and Drug Administration is currently conducting traceback investigations on several items to locate the origin.
