Resumo: | The so called "reversible catalytic model" was applied to the study of certain epidemiological aspects of the human infection by Tripanosoma cruzi. The deterministic model was fitted to prevalence data obtained from populations living in two distinct geographical areas in South America. In spite of the numerous assumptions, which are basic to the model, it was shown that, in general, it describes reasonably well the epidemiologic cynetics of Chagas' infection. The force of infection reflected in 35 effective contacts a year per 1,000 people in a rural area of Venezuela was about three times as large as the force acting upon the population groups living in two small fringe areas of Salvador City, in Brazil. The A. suggests some of the possible further applications of the mathematical model to investigations on the natural history of Chagas' disease. |

O "modêlo catalítico reversível" foi aplicado à análise de dados de prevalência da infecção chagásica em população de duas comunidades de Salvador, Bahia, Brasil e, para efeito de comparação, a dados recentemente publicados e referentes à população de uma localidade venezuelana. Apesar dos numerosos pressupostos básicos ao modêlo, o mesmo descreve bem a cinética da infecção chagásica nas populações. A fôrça da infecção de 35 contatos anuais efetivos por mil habitantes na localidade rural venezuelana revelou-se de magnitude aproximadamente três vezes maior que a fôrça atuante nos grupos populacionais de Salvador, os quais são constituídos, na sua maioria, de migrantes internos oriundos de áreas endêmicas do Estado da Bahia. Foram apontadas algumas das possíveis aplicações práticas do modêlo catalítico reversível ao estudo da história natural da doença de Chagas. Universidade de São Paulo.
