A diarrhea-causing parasitic illness marked by “explosive” watery diarrhea continues to spread across the United States, with reporting of cases increasing in multiple states. Several outlets describe Michigan as the epicenter, with numbers cited as climbing into the thousands and topping earlier counts over the weekend. Estimates in the reports vary by timing, but they consistently place Michigan among the hardest hit, with figures such as more than 700, over 1,200, and claims of several thousand confirmed cases appearing across sources.
Other states in the Midwest and beyond also report growing case counts, including Ohio and New York, and additional states are described as joining the outbreak. One report says cases are present in more than 40 states, while another cites dozens of states reporting activity. Across coverage, health officials and experts say the source of the outbreak is not yet confirmed. One outlet reports that officials identify a potential source, but uncertainty remains about what caused the rise in infections.
The illness can cause prolonged bouts of watery diarrhea lasting for weeks, and experts are working to contain transmission as epidemiologists continue investigating the route of infection.
