The Centers for Disease Control and Prevention (CDC) is investigating an outbreak of cyclosporiasis, a gastrointestinal illness caused by the microscopic parasite Cyclospora. As of mid-June 2026, 145 cases have been confirmed across 17 states, with no deaths reported. The CDC is working with state health officials and the Food and Drug Administration to identify the source of the outbreak.

The advice sounds familiar.
The CDC is once again tracking a parasite that triggers prolonged gastrointestinal illness, with domestic cases climbing for the summer season. Cyclospora, the microscopic parasite responsible, is known to cause cyclosporiasis. The hallmark symptom is watery, often “explosive” diarrhea that can last for weeks or even months if left untreated. The CDC advises anyone experiencing symptoms to contact a healthcare provider for testing and treatment. This guidance has been heard before, as the official outbreak season for the parasite runs from May 1 through August 31, a window where warmer temperatures historically coincide with a spike in infections.
The situation feels like a familiar rerun, as the CDC investigates another outbreak of a parasite that’s been around for years.
