RESUMEN
During 1997 a seroepidemiological study on Chagas' disease was carried out in 18 localities of three provinces (Tocopilla,El Loa and Antofagasta) of Region II (20º 56'-26º south lat.; 70º 38'- 67º west long.), in order to asses the impact of the control program against triatoma infestans launched in 1988, based on insecticide spraying of dwellings. By means of ELISA and an indirect hemagglutination test for chagas' disease blood samples from 1,034 children under 10 years of age were examined, arising a 0.5 por ciento (3 cases) positivity. Test resulted positivite in 2 (0.9 percent) children from the locality of San Pedro de Atacama and 1 (0.4 percent) from Calama city, all in the age group 6-10 year -old. However, none of their dwellings were found infested with T.infestants. These result indicate that the control program has a good possibility to prevent new human infections. It is advisable to continue the seroepidemiological and entomological vigilance and remark the necessity of increasing the effort in the study of transmission through other routes, to adopt or reinforce the pertinent preventive measures:
