Since the incidence cases of FMD is geographically distrbuted along the coast of the county in the continent of Seouth America. 2. Incidence rate of FMD in cattle from Jan. to Dec. 1980 was 1.3 per 100,000 in Uruguay, that of 1.9 per 100,000 in Argentina. 3. The incidence cases of FMD in geographical distribution along the frontier between Uruguay and Brazil showed: 61.5% of the total cases. And where 85.6% of the total outbreak cases of FMD have occured in the vicinity of Buenos Aires in the north of 42˚ the south parallel. 4. The types of FMD virus epizootiologically observed in the outbreak of FMD break down to 95.5% of O type and 4.5% of A type of the total cases in Uruguay, and 73.0% of A type,19.0% of 0 type and 8.0 of C type of the total cases in Argentina. 5.
