Abstract: Thirteen communities from 7 Argentinian provinces were selected for the evaluation of serology as an indicator of transmission of Chagas disease. Of the communities appraised, 6 did not have a history of previous treatment with insecticides and 7 had received sporadic or continuous insecticide treatment. The inhabitants of 20% of the houses of each locality were studied by serology. The samples were obtained by finger pricking and 50 microliters of blood were mixed with 15 microliter of 50% glycerine solution … Show more

“…Community-wide spraying of residual insecticides substantially affects the age-prevalence profile of T. cruzi. 2 In our study, Amamá was sprayed only once with deltamethrin, which mostly eliminated domiciliary infestations between 1985 and 1987, 7 whereas in neighboring Trinidad and Mercedes, no spraying was ever carried out. Therefore, exposures to Triatoma infestans were not homogeneous over time between villages.…”

“…In this region, Triatoma infestans is the main or only domiciliary vector of Trypanosoma cruzi, the causative agent of Chagas disease, and mud-and-thatch houses are the typical rural dwellings. 1,2 The Chaco is one of the most endemic regions for Chagas' disease in the Americas, where an estimated 16-18 million people are infected and an additional 90 million people are at risk of contracting the infection. 3 Although mud-and-thatch houses are usually regarded as homogeneous, the density of triatomines varies widely among them for reasons that are becoming increasingly understood.…”

“…Methodological standardization to achieve this aim has been emphasized in a collaborative work among reference laboratories from Argentina, Brazil and United States (Camargo et al 1986). Serologic assays are required for the diagnosis of patients, identify uninfected blood donors, in serologic surveillance after application of insecticides (Chuit et al 1989), and to determine population serologic profiles (Segura et al 1985). Parameters to evaluate the goodness of a serologic method include sensitivity, specificity, predictive values, the standardization of methods and reagents, and reproducibility, simplicity and cost of the assay (Cura et al 1992).…”

“…4 Serologic surveillance of rural residents after insecticidal campaigns have documented a rapid decrease in the rates of seropositivity for T. cruzi. 5,6 However, these studies have been few and pose problems of external validity (i.e., the degree to which local studies on non-randomly selected communities can be extrapolated to the general population). 7 The annual rate of acute cases of Chagas' disease notified by each province might be used as an index of present human transmission of T. cruzi, but most primary cases are not apparent, patients may not seek medical attention because of distance to health facilities and lack of transportation or economic means, and under-reporting within the health system may be frequent.…”
