CBS News • • general
Key Points:
- Maryland has confirmed 32 cases of cyclosporiasis in 2026, with 28 reported since May 1, amid a broader multi-state outbreak affecting at least 18 states.
- The Maryland Department of Health has not identified a common source for cases reported between May 1 and July 7, though cyclosporiasis typically increases from May through August.
- Cyclosporiasis symptoms include watery diarrhea, stomach cramps, loss of appetite, and extreme fatigue, often appearing about a week after infection, complicating efforts to trace the parasite’s origin.
- The parasite is commonly transmitted via contaminated fresh produce, such as lettuce and raspberries, which are difficult to wash thoroughly due to the parasite’s sticky eggs.
- Health officials recommend washing fruits and vegetables carefully and seeking medical care if persistent watery diarrhea develops, as cyclosporiasis can be treated with antibiotics.
