[Epidemiology of cholera in the world. Development between 1970 and 1980]

The authors present a general review of ten year evolution of the 7th pandemic of cholerae. They discuss the official data known from the country declarations. From the epidemiological features they distinguish a hydric dilution model of cholerae (few cases, few carriers, endemicity) and a direct inter-human contamination type (epidemic outbreaks, no endemicity).
