Clinical findings were analyzed in a group of 57 Orientals and 48 Caucasians infected with Clonorchis sinensis and compared with those in a control group of uninfected individuals. Abdominal symptoms were rare in the Orientals and common in Caucasians whether infection was or was not present. Laennec's cirrhosis was more common in the Orientals, infected or not. Hepatomegaly, splenomegaly, peptic ulcer or eosinophilia was not found in either infected group in excess over its control group. These facts are presented in favor of the benignity of clonorchiasis.
