ABSTRACT
This chapter presents the results of the environmental associative analysis carried out in the three field sites between October 1993 and July 1994. The pattern of disease by communal unit in Quelimane was found to be distinctly clustered in favour of higher incidence of cholera in the north-western flanks and higher incidence of dysentery in a large part of the other areas. In the case of Beira, the overall physical environmental conditions were found to differ from those of Quelimane. The pathogenic particularities of Beira's 1992 cholera epidemic suggests it was part of a epidemic wave of the disease and therefore environmental reservoirs can be expected to be less of a factor in that instance. In Gorongosa, where there is no evidence of physical features that disproportionately influence cholera, there exists the possibility that the differences in distribution between the two diseases relate to greater communicability of dysentery.
