Notwithstanding a recent outbreak in Georgia, Cyclospora is the least common intestinal protozoan reported in the United States.  In the following chart, I have summarized the incidence of cyclosporiasis, giardiasis, amebiasis and cryptosporidiosis. As indicated at the black arrow, ongoing trends for amebiasis (no longer reported as of 1994 = 2,983 cases) were “continued” by reports of cryptosporidiosis (2,972 cases in 1995).
