The invasion occurs in China, Korea, Taiwan, Japan and Vietnam, but is more prevalent in South China. Clonorchiasis results from the invasion to bile ducts by the trematode — Clonorchis sinensis. This is a flat elongated worm about 4 cm. which produces numerous ova 19X19 microns in size. Dogs, cats and pigs may be infected in addition to man. To complete the life cycle the eggs must be ingested by a freshwater snail and then cercaria, which leave it and enter a freshwater fish. If this fish is eaten raw or insufficiently cooked, the man becomes infected.
