The CDC parasite outbreak count reached 145 U.S. cases of cyclosporiasis across 17 states as of June 16. CDC said it had no evidence of a single multistate source, even as the illness moved through the United States during the summer season.
Of the 145 people who became ill after eating food in the United States, 20 were hospitalized and none died. The cases involved people ages 5 to 86, with a median age of 42.
CDC June 2 statement
On June 2, CDC said, "CDC has no evidence of a single, multistate Cyclospora outbreak linking cases happening right now and being reported in press." It also said, "The data currently found on CDC’s website is a surveillance count of cases across the United States of people with cyclosporiasis."
CDC added, "This number includes clusters of cases currently under investigation by FDA and cases that have not been linked to a common source." That means the total on the dashboard is broader than one outbreak and can include illnesses still being sorted into separate investigations.
Michigan case counts
The comparison with Michigan adds the clearest friction to the picture. Michigan reported more than 170 cases by July 1, while CDC had no evidence tying the current illnesses together as one multistate event.
Michigan's total was about 50 last year, a jump that stands out even though CDC's national count includes cases under investigation and cases not linked to a common source. For readers in affected states, the practical point is simple: the dashboard is a surveillance count, not a final source attribution.
CDC dashboard in June
CDC said its cyclosporiasis surveillance dashboard is updated monthly, and on July 2 it said it did not have new data to provide. The illness season began May 1 and runs through the end of August, so the June 16 count came during the period when cases typically accumulate.
The open question is the one that matters most for prevention: what specific food source or produce item is responsible for the current cyclosporiasis cases. Until that is identified, the count shows spread across 17 states, but not a single source anyone can point to yet.
