> **Open Intelligence Dossier** · First detected: 2026-07-01 19:07 UTC · Category: Health

## Executive Summary
A large and growing outbreak of cyclosporiasis, a parasitic infection characterized by severe diarrhea, has been reported across 17 U.S. states.

## Intelligence Brief
Health officials are monitoring a multi-state outbreak of cyclosporiasis. The condition, which is caused by the Cyclospora parasite, has been reported in at least 17 states. Michigan has seen a notable increase in reported cases within a five-day window, and officials are investigating clusters of the illness across the country.


Coverage from outlets including The New York Times, ABC News, and Fox News highlights that the infection is often linked to the consumption of certain foods, specifically salads and berries. Some reports detail a focus on potential contamination sources associated with these food items during the summer season. The CDC is currently investigating the source of the outbreak.


Future updates are expected to clarify which specific food items are linked to the rise in infections and whether the geographic reach of the parasite will expand beyond the currently affected states.
