The distribution of leptospirosis in Latin America.
Although many factors combine to make Latin America an apparently suitable region for the spread of the leptospiroses, the prevalence of these infections has been studied in relatively few areas of this part of the American continent. Of the 60 Leptospira serotypes described in the world, only seven have so far been definitively demonstrated in Middle America and five in South America. However, there is evidence to suggest that other and perhaps new serotypes may be found, and recent serological surveys indicate that there are loci of multiple leptospirosis affecting a large percentage of human or animal populations in at least five Latin American territories.The true prevalence of leptospirosis can only be ascertained by the proper application of reliable laboratory diagnostic methods. The limited value of certain techniques used heretofore makes a number of reports on the presence of this disease subject to question.
