## Executive Summary
The CDC reports an all-time high of over 11,500 cyclosporiasis cases across 41 US states, with massive spikes in Michigan.

## Intelligence Brief
The Centers for Disease Control and Prevention (CDC) has reported that more than 11,500 cases of cyclosporiasis have occurred across 41 states. This surge represents an all-time high for cyclospora cases in the United States. In Michigan, health officials state that cases have climbed to over 7,000, which the Detroit Free Press specifies is a 9% increase in infections within that state. The outbreak is manifesting as a rise in cases of explosive diarrhea, a trend specifically noted by WAFB in Louisiana. This health crisis has already led to the recall of lettuce in South Carolina, which has been tied to the parasite outbreak according to reporting from The State. Coverage of the crisis is widespread, with ABC News focusing on the remaining unknowns regarding the outbreak as case numbers continue to rise.


The Washington Post reports that the CDC is currently working to catch up to state tallies as the illness surges. Regional outlets such as ClickOnDetroit and WDIV Local 4 have focused heavily on the Michigan situation, where numbers have exceeded 7,000. The Hill has highlighted the historical nature of this event, noting that the number of suspected cases has surpassed 11,000 and detailing the specific states experiencing the most significant spikes in infection rates. Contextual reporting from The New York Times examines the biological nature of the parasite, noting that Cyclospora spreads through human feces and questioning how the parasite entered the broader food supply. This biological factor is central to the current crisis, as the link between the parasite and the food supply is evidenced by the recall of lettuce in South Carolina. The scale of the outbreak is unprecedented, moving from isolated regional spikes to a coordinated national health emergency involving nearly every state in the union, with Michigan emerging as a primary epicenter for the surge.


Future developments will likely center on the ongoing efforts by the CDC to finalize case counts and align them with state-level data. According to ABC News, there are still significant gaps in knowledge regarding the outbreak that health officials have yet to resolve. Observers will be watching for further food recalls similar to the lettuce action in South Carolina as investigators trace the parasite's path from human feces into the food supply. The continued trajectory of infections in Louisiana and Michigan remains a critical point of monitoring as state health officials track the spread of the diarrhea parasite.
