Federal health officials at the Centers for Disease Control and Prevention (CDC) have announced that the total number of confirmed cyclosporiasis cases in the United States has reached 15,716. Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis, which is typically transmitted through the consumption of contaminated food or water.

Investigations into the source of the outbreak are ongoing. According to the CDC, current evidence points toward iceberg lettuce as a primary vehicle for the parasite. The infection is characterized by symptoms including frequent, sometimes explosive, watery diarrhea, loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea, and fatigue. If left untreated, the illness can persist for several weeks or even months.

The CDC continues to monitor the situation and coordinate with state and local health departments to identify the specific points of contamination. While the current report highlights the significant rise in case numbers, officials have not yet provided a definitive timeline for when the outbreak might be considered contained. Public health guidance remains focused on proper food handling and washing produce, though the CDC notes that the parasite can be difficult to remove from leafy greens once contaminated.
