RESUMO

This study assessed public acceptance for two new vectorial control techniques for Chagas' disease: insecticidal paint and fumigant canisters. The study compared the two with traditional fenitrothion insecticide spraying. An experimental field study was performed in an endemic area of central Honduras from August to November 1992, a year after the initial application of the treatments. The objectives of the study were to determine the acceptability of the tools on the part of the population whose homes were treated, and on the part of the personnel applying the treatments. The sample size was drawn up according to a uniform protocol applied in six Latin American countries. For this study a total of 651 persons were surveyed in 15 rural communities. Along with the surveys, focus groups were used to collect information to learn the reasons for accepting or rejecting particular treatments. The survey was done with heads of households. Focus groups were done with heads of households and also with the field operators who applied the treatments. The research showed that insecticidal paint had a low level of community acceptance (28.8 percent). Field operators strongly disliked the paint because of problems with its transport, application, unpleasant smell, and very low effectiveness against triatomines and pest insects. The results showed that in order to increase the public acceptance for insecticidal paint, it would be necessary to make the paint easier to transport and apply and to increase its effectiveness. Because of their very low effectiveness, fumigant canisters did not represent an acceptable alternative for triatomine vector control. A public educational effort should be a component of any new control method developed (AU)

RESUMO

This article presents a brief review of American trypanosomiasis (Chagas' disease) in the Caribbean, an area generally considered non-endemic for the infection (AU)

RESUMO

Wild-caught and laboratory-bred Triatoma dimidiata were studied in British Honduras. Newly hatched nymphs were very reluctant to feed in the laboratory, but later instars fed readily. Armadillos and rabbits were the most acceptable hosts; man was unattractive even to starved insects. Nymphs and adults of laboratory fed T.dimidiata were fed on white rats infected with Trypanosoma (Schizotrypanum) cruzi and all acquired gut infections and remained infective for life. T. dimidiata does not defaecate during or immediately after feeding, and it is suggested that infection by direct faecal contamination is most unlikely; the infective faecal material may be carried to a wound, to the conjunctiva of the eye or to the oral or nasal mucosa after the insect has been squashed on the human body.(Summary)
