Michigan cyclosporiasis outbreak cases rise

United States — Michigan remains the hardest-hit state in a multistate outbreak of cyclosporiasis, a parasitic illness linked to iceberg lettuce sourced from Taylor Farms operations in central Mexico. As of August 20, United States — Michigan reported 14,277 cases, up 368 from the previous week, with two deaths among individuals with underlying health conditions. The U.S. United States — Centers for Disease Control and Prevention reported 15,716 laboratory-confirmed cases across 47 states as of August 18. United States — Wayne County, Michigan had the most cases (2,029), followed by United States — Oakland County, Michigan (1,499). People aged 30-39 accounted for the largest number of infections. Health officials noted that new case reports were slowing and that increases partly reflected a testing backlog. Corewell Health issued guidance on July 22 indicating test result delays of 8-21 days due to high volume and reagent shortages. Dr. Michael Osterholm of the University of Minnesota suggested the latest cases reflect backlog rather than ongoing transmission. The outbreak has shaken consumer confidence in fresh produce and restaurants.
