Michigan's Cyclospora cayetanensis outbreak climbed to 1,562 confirmed cases as of Friday morning's update from the Michigan Department of Health and Human Services — a jump of more than 300 from the 1,251 reported Thursday morning — as the parasitic illness continues to spread across the state and investigators remain unable to identify a food source after more than two weeks of active investigation.
Forty-four people have been hospitalized. Cases have now been confirmed in 43 of Michigan's 83 counties, including counties in the northern Lower Peninsula and even the Upper Peninsula — a geographic spread that underscores how rapidly an outbreak whose source remains unknown can expand when no targeted recall or advisory is possible.
