As of July 25, 2013, CDC has been notified of 321 cases of Cyclospora infection in residents of 14 states and one city, including Iowa, Nebraska, Texas, Florida, New York City, Wisconsin, Georgia, Missouri, Arkansas, Connecticut, Minnesota, New Jersey, and Ohio. Illinois and Kansas have also notified CDC of one case each that may have been acquired out of state but in the United States.

Most of the illness onset dates have ranged from mid-June through early July.

At least 18 persons reportedly have been hospitalized in three states.

No food items have been implicated to date, but public health authorities are pursuing all leads. Previous outbreak investigations have implicated various types of fresh produce.  See also, www.outbreakdatabase.com.

My bet is an imported leafy green.
