- Two people in Michigan have died in connection with the outbreak of cyclosporiasis, health officials reported Monday. These are the first known deaths related to the multi-state outbreak of explosive diarrhea in the United States.
- The Michigan Health Department confirmed that both individuals had significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration.
- Deaths from cyclosporiasis are far from common, as the infection is generally not a life-threatening illness, according to health officials.
- Michigan has reported a total of 11,234 cases of cyclosporiasis, including 193 hospitalizations tied to the outbreak.
- Cyclosporiasis is caused by a microscopic parasite that can contaminate fresh food or water and lead to severe diarrhea in those infected.
- The CDC has identified more than 18,000 cases of domestic cyclosporiasis this season, with 6,707 cases confirmed and about 11,500 others undergoing further laboratory testing.
- In mid-July, Taylor Farms recalled iceberg lettuce from central Mexico that was believed to be the source of the outbreak.

The outbreak has resulted in 11,234 reported cases in Michigan, with 193 hospitalizations. The CDC has noted that the state appears to be the hardest hit, with its case count surpassing national figures.

Cyclosporiasis, caused by a microscopic parasite, typically contaminates fresh food or water, leading to severe diarrhea. The illness is known to peak during the spring and summer months, with a typical season running from May to August. Although deaths from cyclosporiasis are rare, the Michigan Health Department emphasized that the infection is generally not life-threatening.3
In mid-July, a recall of iceberg lettuce from central Mexico was issued by Taylor Farms, believed to be the outbreak's source. The FDA is also investigating additional cyclosporiasis outbreaks, as health officials continue to monitor the situation closely.7
“Michigan has reported 11,234 cases and 193 hospitalizations, making it the hardest-hit state; CDC has tallied more than 6,700 lab-confirmed cases since May 1.
