The occurrence of transmissible gastroenteritis (TGE) appears to be worldwide wherever swine are raised. This disease has been reported in Denmark, England, Germany, Japan, Canada, Holland, and the United States. During the early 1930's reports began to appear in the literature regarding a disease condition in baby pigs which caused an extremely high rate of mortality.
