The danger that cholera is becoming endemic in Latin America makes it imperative to know the geographic location of aquatic environments where ecological conditions favor long-term survival of the toxigenic Vibrio cholerae O1 El Tor biotype, and such aquatic environments should be sampled to determine if they harbor this microorganism. For efficient and effective sampling, it would be useful to know what kinds of waters are ecologically suitable for the survival of this pathogen during periods between epidemics, and where these bodies of water are located. This paper presents the hypothesis that toxigenic V. cholerae O1's ability to survive in surface freshwaters tends to be inversely related to the altitude above sea level of these freshwaters.
