Modelling congenital transmission of Chagas' disease.
The successful elimination of vectorial and transfusional transmission of Chagas' disease from some countries is a result of the reduction of domestic density of the primary vector Triatoma infestans, of almost 100% of coverage in blood serological selection and to the fact that the basic reproductive number of Chagas' disease is very close to one (1.25). Therefore, congenital transmission is currently the only way of acquiring Chagas' Disease in such regions. In this paper we propose a model of congenital transmission of Chagas' disease. Its aim is to provide an estimation of the time period it will take to eliminate this form of transmission in regions where vetorial transmission was reduced to close to zero, like in Brazil.
