Hawaii Confirms 1st 2026 Cyclosporiasis Case in Visitor as 34 States Report Outbreak

Summary
Hawaii health officials confirmed the state's first cyclosporiasis case of 2026 in a visitor who developed symptoms after arrival and is believed to have been infected before reaching the islands.
That means the case will not be counted in Hawaii's resident total, and the Department of Health said the overall threat to Hawaii residents remains low.
34 states have now reported cases in a mainland outbreak that began in Michigan, with the CDC confirming 1,645 infections since May and tracking more than 5,100 additional potential cases.
Michigan officials suspect lettuce may be linked, but federal investigators have not confirmed a source; Hawaii is urging travelers and residents to wash produce and watch for diarrhea, abdominal pain, nausea and fever.
Over the past 10 years, Hawaii has recorded just 3 resident cases, all tied to travel outside the state with no evidence of local transmission.
