Abstract

Chagas disease is caused by the parasite Trypanosoma cruzi. In Argentina, Triatoma infestans is its main vector. Its occurrence has been documented in rural areas, although currently also in urban areas of the Northwest and Cuyo, including San Juan(1,2,3). With the aim of conducting an ecoepidemiological study in an urban setting, a cross-sectional study was carried out in Villa San Roque, Rivadavia Department, San Juan, during October 2022. Entomological assessments, sociodemographic and social practices surveys were conducted on adult residents of the dwellings that allowed access. High participation was observed (89%, n = 179/201 dwellings assessed), mainly women (57%). 71% of the respondents had an age range between 18-64 years, while the remaining 29% were over 65 years of age. 90% were born in the province of San Juan and 81% were born in urban areas. In the houses infested by T. infestans (n = 20), the most frequent wall materials were ceramic bricks and adobe (40% in both cases); while 65% of the roofs were wood. 55% of the participants had secondary education, the most frequent work activity was self-employment (45%), 50% had applied some insecticide in the last year and 70% had domestic animals. The results show that we are dealing with a complex socio-environmental phenomenon that develops in a densely populated environment. Further studies are essential to better understand the epidemiological status in the urban area and its associated characteristics(4,5)
