Perceptions about Chagas disease importance and prevention in rural community of Los Llanos riojanos

Abstract

INTRODUCTION: The province of La Rioja is endemic for Chagas disease, which is primarily transmitted by its vector, thehematophagous insect Triatoma infestans (vinchuca). The objective of this work was to develop a comprehensive approach in order to knowthe importance given by the community to Chagas disease and its vectors, and to survey information related to the prevention of transmission.METHODS: A cross-sectional study was carried out with a non-probabilistic mixed approach through a semi-structured questionnaire. Theperception of 96 residents from 41 localities of Los Llanos community, La Rioja, was explored. RESULTS: T. infestans took the sixth place amongthe animals residents are most worried about. While 83% of the people interviewed were capable of correctly identifying T infestans adultswhen compared to other triatomine bugs, 79% expressed confusion regarding the vector transmission process of Chagas disease. Henhouseswere recognized as the most common place to find vinchucas, followed by corrals. Besides, 92% reported they had never collected insectsfound in their housing to have them analyzed in health facilities. DISCUSSION: This descriptive research provided useful information to guidethe work with local communities and to identify aspects to be addressed to avoid the vector transmission of Chagas in the area of study.
