[Role of interhuman infection during the cholera epidemic in the People's Republic of the Congo (1978-1979)].

The authors make an epidemiologic analysis of the first cholera cases notified by the Congo in 1978 and 1979. Contrary to the explosive cholera, experiences by Burundi and Zaïre during the same period, the cholera, in the Congo, had a very subtle propagation, with the well-know "iceberg" phenomena. Human contacts were very important in the transmission of the disease. The cases encountered were almost exclusively of the family type. Healthy carriers represent a threat to the other countries.
