Overview
- Michigan has reported more than 700 cyclospora cases since June 22, forming the largest identified cluster in the current rise.
- Overall case counts now exceed about 600 infections across 18 states with notable totals in Illinois (141), Ohio (177) and upstate New York (112).
- State health departments are working with the CDC and FDA but have not identified one common food or water source because Cyclospora needs days to weeks in the environment to become infectious.
- The infection causes very watery, persistent diarrhea plus nausea, cramps and fatigue and public guidance urges handwashing, thorough washing of produce, prompt refrigeration of cut items, hydration and medical care including antibiotics when prescribed.
- Officials warn summer produce and complex supply chains can prolong investigations, and continued patient interviews and product tracing will determine whether a single supplier or multiple exposures are responsible.
