Michigan health officials said Aug. 3 the state’s cyclosporiasis outbreak has tallied 11,234 cases, 193 hospitalizations and two deaths, as of July 30.
The two individuals who died “had significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration,” according to medical records accessed by the Michigan Department of Health and Human Services. “Cyclosporiasis is generally not a life-threatening illness. Death resulting from cyclosporiasis is uncommon in the United States.”
The Michigan health department will not provide additional information on these two deaths, according to an Aug. 3 update of the state’s outbreak.
Michigan has been the hardest-hit state of the outbreak, which has hit 45 states between May 1 and July 27, according to the most recent CDC data. Federal officials are tracking several transmission chains linked to the parasitic illness, including iceberg lettuce.
The CDC’s public-facing webpage providing details of the cyclosporiasis outbreak, last updated July 28, reports 7,725 confirmed cases, 465 hospitalizations and zero deaths. The agency said it is aware of more than 11,500 probable cases not yet confirmed, many of which are from Michigan and Ohio.
Ohio has reported 4,013 cyclosporiasis infections in 2026. Five days prior, the state counted 2,576 cases.
