CULTURAL KNOWLEDGE AND EXPERIENCES OF TRIATOMINES AND CHAGAS DISEASE IN THE CITY OF MÉRIDA, MEXICO

Abstract

Human-k triatomine insects’ interaction is a milestone in Chagas Disease (CD) prevention and control. We studied and compared ethnoecology and cultural knowledge and experiences about triatomines and Chagas of two urban social groups, and of health technicians of the vector control program in Merida city, southeastern Mexico. We conducted semi-structure interviews: 24 participants living in very low marginalization index (VLMi) and 26 of very high marginalization index (VHMi) areas in Merida, and 15 health workers. Questions focused on ethno-ecology and health-related knowledge of blood-sucking insects, and experiences on triatomine bites and CD, same than treatment and diagnosis of both bites and the disease. A thematic content-analysis and descriptive statistics were followed. Triatomines were considered a health danger due to the perception of them as poisonous and causing infection. Participants of VLMi were more knowledgeable about CD compared to VHMi participants, but they had limited understanding of the overall to chronicity when compared to health technicians. VHMi showed a more elaborate ethno-ecological knowledge about triatomines and had more exposition to them. Across participants, a biased understanding about CD has been recorded, since it was given emphasis only on acute phase aspects but not on chronic symptomatology. Cultural knowledge about CD remains rather theoretical since it keeps a very unfamiliar disease due to the lack of individual and collectively shared experiences on therapeutic itineraries and illness. There is an urgent need to focus on CD also as a chronic disease by giving more visibility to its prevalence, more advances in diagnostic and treatment, a proper medical care need, as well as illness experiences, and its human impact.
