Public health surveillance data highlights a notable wave of domestically acquired cyclosporiasis infections circulating across multiple regions, including Missouri and neighboring states. Cyclosporiasis is a gastrointestinal illness caused by a microscopic parasite typically transmitted through contaminated fresh produce or water supplies. Affected individuals frequently experience persistent watery diarrhea, loss of appetite, weight loss, abdominal cramping, nausea, and fatigue. State and federal health agencies continuously investigate these outbreaks to trace contaminated food supply chains.
