Michigan Reports First Two U.S. Deaths Related to Diarrhea-Causing Parasite

Two individuals have died in Michigan's recent Cyclospora outbreak, marking the first U.S. deaths linked to the intestinal parasite, state health officials announced on Monday. Both victims had underlying health conditions that may have exacerbated the illness and dehydration. The Michigan Department of Health and Human Services declined to disclose further details about the fatalities.

Cyclospora, a microscopic parasite, typically triggers severe watery diarrhea and frequent bowel movements. Outbreaks often occur during late spring and summer months. While rarely fatal, the illness, known as cyclosporiasis, is less common than other foodborne pathogens like Salmonella and E. coli. Historically, few U.S. Cyclospora outbreaks were reported; however, the frequency has surged in recent years, with over 18,000 confirmed or suspected cases in the ongoing outbreak.

The CDC has identified lettuce imported from Mexico, served at Taco Bell locations across nine states, as a significant source of the widespread outbreak. As of late July, 1,947 cases linked to the contaminated lettuce were confirmed, including at least 98 hospitalizations. The agency asserts that other brands, restaurants, retailers, or distribution channels may also be implicated as the investigation continues.
