# Map: Where cases of ‘explosive’ diarrhea-causing parasitic illness have been reported

> **Open Intelligence Dossier** · First detected: 2026-07-09 18:07 UTC · Category: Health

## Executive Summary
Cyclosporiasis cases are rising across the United States, prompting food warnings and health investigations across multiple regions.

## Intelligence Brief
Reports of cyclosporiasis, a parasitic illness characterized by severe, explosive diarrhea, are increasing across at least 25 states. The FDA has issued food warnings as investigations continue into potential links with produce, specifically lettuce, and specific food chains. Coverage from outlets including The Columbus Dispatch, USA Today, Bloomberg, and The New York Times emphasizes the geographic spread and distinguishes the illness from other gastrointestinal conditions.


UC Davis Health and other news organizations highlight that the parasite, Cyclospora, is the primary agent behind these cases. North Carolina officials have logged 240 cases since May, while Michigan reports indicate more than 1,000 cases. Public health agencies continue to monitor the transmission of the parasite.


Future developments depend on whether investigations identify definitive food sources or specific supply chain origins for the contamination. Coverage does not yet specify the total national case count or the timeline for the containment of the current outbreak.
