## Executive Summary
A multi-state outbreak of cyclosporiasis is prompting restaurant menu changes and health warnings across the United States.

## Intelligence Brief
A parasite outbreak of cyclosporiasis is currently affecting multiple states, causing symptoms described as explosive diarrhea. Coverage from NewsNation has highlighted the spread of the infection through a map detailing the outbreak by state. The impact is being felt in various urban centers, where individuals have reported severe illness. In Chicago, a patient spoke with CBS News regarding an uncomfortable experience with the parasite, warning others to avoid the condition if possible. Different news outlets are focusing on the localized responses to the health crisis. In Lincoln, Nebraska, local news source KOLN reports that restaurants have temporarily pulled specific menu items from their offerings in the midst of the cyclosporiasis outbreak.


Meanwhile, in Columbia, KOMU 8 reports that produce distributors remain confident despite the emergence of cyclosporiasis cases in the area. CNN has shifted its focus toward patient guidance, providing a resource for those who believe they have caught the diarrhea-causing parasite on what steps they should take next to manage their health. Context for this trend involves the nature of the parasite itself and how it enters the food supply. Cyclospora is identified as the cause of the diarrhea associated with these reports. The involvement of produce distributors in Columbia and the removal of menu items in Lincoln suggest a link between the parasite and consumed food products. Because the outbreak is appearing across different states and cities, such as Chicago and Lincoln, health officials and media outlets are monitoring the geographic distribution of the cases to identify the source and protect the public from further infection.


Future developments will likely center on the identification of the specific contaminated food items that led to the outbreak. Coverage will likely follow whether Lincoln restaurants reinstate their pulled menu items or if more establishments follow suit. There is also a need for continued monitoring of produce distributors in Columbia to see if their confidence is maintained as more cases are reported. As CNN continues to provide guidance for suspected patients, the focus will remain on the medical response and the effectiveness of the current state-by-state mapping provided by NewsNation.
