As of September 14, 2015 (3pm EDT), a total of 546 ill persons with confirmed Cyclospora infection were reported to CDC in 2015. Most of these persons—319 (58%) of 546—experienced onset of illness on or after May 1, 2015, and did not have a history of international travel within 2 weeks before illness onset.

Clusters of illness linked to restaurants or events have been identified and investigated in Texas, Wisconsin, and Georgia. Epidemiologic and traceback investigations conducted in Texas, Wisconsin, and Georgia by state and local public health and regulatory officials and the FDA indicated that some illnesses among residents in these states were linked to fresh cilantro from Puebla, Mexico. The vehicle(s) of infection for non-cluster-associated cases has not been identified. The numbers of reported cases of cyclosporiasis in the United States have returned to baseline levels.
