## Executive Summary
The CDC is investigating a national cyclosporiasis outbreak with nearly 7,000 confirmed or suspected cases across the United States.

## Intelligence Brief
A widespread outbreak of cyclosporiasis has emerged across the United States, with the Centers for Disease Control and Prevention (CDC) reporting that nearly 7,000 cases have been confirmed or are currently under investigation nationwide. The scale of the parasite outbreak is extensive, with The Detroit News noting that a Michigan parasite outbreak has been linked to cases appearing in three other states. In the Pacific, health officials in Hawaii have confirmed one specific case of cyclosporiasis in a visitor to the islands, though local authorities maintain that the overall risk to residents of Hawaii remains low at this time. Major news outlets are focusing on the source of the contagion and the geographic distribution of the illness. NBC News highlights the CDC's data regarding the total number of cases, while the Wall Street Journal reports that health officials are currently zeroing in on lettuce as part of an explosive-diarrhea outbreak probe.


Regional coverage from KTLA emphasizes the need for public awareness as cases rise. Meanwhile, in the Northeast, a doctor from Tufts, as reported by WCVB, suggests that Massachusetts is unlikely to see as many cyclospora cases as those appearing in the Midwest region of the country. To understand the current stakes, it is necessary to note that the parasite is causing significant gastrointestinal distress, described by the Wall Street Journal as explosive diarrhea. The regional variation in cases suggests that the distribution of the contaminated product may be concentrated in certain areas, particularly the Midwest. In response to the national trend, KITV has encouraged individuals to shop locally as a preventative measure to avoid bringing the national outbreak further into Hawaii, reflecting a concern over the movement of contaminated produce across state lines.


Future developments will depend on the results of the ongoing probe into the food supply. According to reports from the Honolulu Star-Advertiser and Hawaii News Now, officials will continue to monitor visitors and residents to determine if the risk level in Hawaii changes. The primary focus for health officials, as indicated by the Wall Street Journal, remains the investigation into lettuce. Further updates from the CDC are expected as more of the nearly 7,000 under-investigation cases are confirmed or ruled out.
