Avaliação do sistema de vigilância entomológica da doença de Chagas com participação comunitária em Mambaí e Buritinópolis, Estado de Goiás

Abstract

A vigilância entomológica da doença de Chagas em Mambaí e Buritinópolis, no Estado de Goiás, Brasil, tem sido mantida com participação da população, notificando a presença de vetores nas habitações. Passado longo tempo após instituídas as ações de controle e tendo-se já certificado a interrupção da transmissão vetorial, buscou-se avaliar o conhecimento e as práticas da população nessa situação. Os resultados apontam progressivo desinteresse pelo tema doença de Chagas, atribuível à redução da magnitude do problema representado pela enfermidade, a pouca participação das escolas na vigilância, à pequena importância dos vetores secundários e nativos e, em conseqüência, às limitadas intervenções dos serviços de controle em resposta às notificações. Propõe-se, que atividades de busca direta por amostragem sejam periodicamente realizadas e maior envolvimento das instituições de ensino.Palavras-chaves: Doença de Chagas. Vigilância entomológica. Participação comunitária. ABSTRACTEntomological surveillance of Chagas disease in Mambaí and Buritinópolis, in the State of Goiás, Brazil, has been kept up through the local population's participation, consisting of reporting the presence of vectors inside their homes. A long time has elapsed since instituting these control measures and it has now been certified that vector transmission has been halted. Thus, this study sought to evaluate the population's knowledge and practices in this situation. The results show that there has been progressive indifference towards the topic of "Chagas disease", which can be attributed to the reduction in the magnitude of the problem that this disease represented, little participation in surveillance among schools, low epidemiological importance of secondary and native vectors and, consequently, limited control interventions from health services in response to notifications. It is proposed that direct search activities by means of sampling should be carried out periodically, and that there should be greater involvement among teaching institutions.

Validation of a documentary on Chagas disease by a population living in an endemic area

“…All interviewees cited at least one organ, such as the heart, that can be damaged. With regards to this topic, these data corroborate the ones found by Williams-Blangero et al (1999) and Silveira et al (2009), in northeastern Goiás state, Brazil, since the heart was the most cited organ by participants in the study.…”

Human Chagas Disease and Migration in the Context of Globalization: Some Particular Aspects

“…Vector transmission seems to be improbable, in spite of the eventual detection of housing invasion by T. rubrofasciata and Linshcosteus sp. in Southern Asia [25, 39, 51]. The main preoccupation concerns the demand for medical attention and social security, a problem which has been highly complicated because of the clandestine situation of thousands of LA migrants and the lack of medical expertise in nonendemic countries [17, 50, 52].…”

“…Current theories indicate that triatomines detected in Southeast Asia have probably derived from American species passively carried to seaports by sailing ships since the sixteenth century [38, 55]. The construction of railways and roadways has also played a significant role in the dispersion of domestic vectors in endemic countries [28, 38, 51, 54]. …”

“…After 2020, with the progression of transmission control and the natural aging of infected people, the demand for specific treatment will decrease significantly. In pragmatic terms, globalization tends to facilitate specific treatment, bettering the availability of drugs around the world, chiefly with the assistance of health and humanitarian institutions such as WHO, PAHO, DNDI, and MSF [19, 21, 51]. …”

“…Decentralization of health services and the reduction of vertical programs have been a consequence of globalization, putting the major responsibility of medical care and control programs on peripheral governmental levels [17, 39, 51]. Contextual difficulties and inequities exist but must be overcome by a universal effort involving people, governors, and scientists effectively compromised with poor populations.…”
