Malaria ecology--the Trinidadian aspect.

Abstract

Triad models serve as reference points for the examination of etiological factors and salient features in Trinidad's malaria control efforts. Adaptive mechanisms and 'role-switching' in biological and cultural evolution are highlighted as are the significance of environment and man-environment forces. A community model is presented which incorporates an inventory of somatic and psychological factors, risk-taking behaviours, and environmental and material resources pertaining to specific diseases which a particular habitat and population group maintain.
