Cluster analysis of malaria incidence in Guyana revealed a relationship between population migration intensity and increased rate of P falciparum infection. Such a relationship was not detected for P. vivax malaria. Seasonal differences in malaria incidence are explained by changes in vector ratio. Malariogenic stratification helped clear out the role of three main malaria vectors in different regions of Guyana.

The suggested systemic approach to malaria epidemiology may be crucial for the concept of malaria epidemic process and malaria control policy. From a practical viewpoint this approach will help determine the framework for rational malaria stratification and priority directions of investigations.
