  • * N=490. Data are current as of 5pm EDT, 8/12/13. Data are preliminary and subject to change. Some illness onset dates have been estimated from other reported information. A case is defined as laboratory-confirmed Cyclospora infection in a person with onset of illness since June 2013 and no known history of travel outside of the United States or Canada in the 14 days prior to onset of illness. Illnesses that occurred after July 6, 2013, might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This could take up to 4 to 5 weeks. It is not yet known whether all reported cases are part of the same outbreak.
