“…Our data show how the social representation of the disease ranges in a continuum from a common disease to a deadly disease. Absence of symptoms together with the lack of impact on day-to-day activities has contributed to the normalisation of the illness ( 37 , 40 , 41 ) to the point where Chagas is not considered a disease ( 25 ).…”

BackgroundIn Europe, Spain has the highest number of people with Chagas disease (CD). Bolivian migrants account for 81% of the reported cases. One of the priorities in controlling the disease is prevention of mother-to-child transmission. Despite under-diagnosis in Spain being estimated at 90%, there are currently few studies that explore the social and cultural dimensions of this disease.ObjectiveThe aim of this study was to explore the knowledge and experiences of Bolivian women with CD, in order to generate a useful understanding for the design and implementation of public health initiatives.DesignQualitative study based on semi-structured interviews, triangular groups, and field notes.ParticipantsFourteen Bolivian women with CD living in Madrid.ResultsThe participants were aware that the disease was transmitted through the vector, that it could be asymptomatic, and that it could also be associated with sudden death by heart failure. They opined that the treatment as such could not cure the disease but only slow it down. There was a sense of indifference along with a lack of understanding of the risk of contracting the disease. Participants who presented with symptoms, or those with relatives suffering from the disease, were concerned about fatalities, cardiac problems, and possible vertical transmission. There was also a fear of being rejected by others. The disease was described as something that affected a large number of people but only showed up in a few cases and that too after many years. There was a widespread assumption that it was better not to know because doing so, allows the disease to take hold. ConclusionsDisease risk perception was very low in Bolivian women living in Madrid. This factor, together with the fear of being screened, may be contributing to the current rate of under-diagnosis.

“…Chagas disease constitutes a serious problem in Latin America, where it has been estimated that about 10 million people are infected with the causative parasite, Trypanosoma cruzi [ 1 ]. Important advances have been made in reducing transmission by the vector Triatoma infestans , particularly in countries within the southern cone of South America [ 1 ], [ 2 ], [ 3 ], and Rhodinus prolixus in Central America [ 4 ],[ 5 ]. However, limited progress has been achieved in Ecuador, where neither accurate estimations of prevalence nor of people at risk of becoming infected by T .…”

BackgroundChagas disease is endemic to the southern Andean region of Ecuador, an area with one of the highest poverty rates in the country. However, few studies have looked into the epidemiology, vectors and transmission risks in this region. In this study we describe the triatomine household infestation in Loja province, determine the rate of Trypanosoma cruzi infection in triatomines and study the risk factors associated with infestation.Methodology/Principal FindingsAn entomological survey found four triatomine species (Rhodnius ecuadoriensis, Triatoma carrioni, Panstrongylus chinai, and P. rufotuberculatus) infesting domiciles in 68% of the 92 rural communities examined. Nine percent of domiciles were infested, and nymphs were observed in 80% of the infested domiciles. Triatomines were found in all ecological regions below 2,200 masl. We found R. ecuadoriensis (275 to 1948 masl) and T. carrioni (831 to 2242 masl) mostly in bedrooms within the domicile, and they were abundant in chicken coops near the domicile. Established colonies of P. chinai (175 to 2003 masl) and P. rufotuberculatus (404 to 1613 masl) also were found in the domicile. Triatomine infestation was associated with surrogate poverty indicators, such as poor sanitary infrastructure (lack of latrine/toilet [w = 0.95], sewage to environment [w = 1.0]). Vegetation type was a determinant of infestation [w = 1.0] and vector control program insecticide spraying was a protective factor [w = 1.0]. Of the 754 triatomines analyzed, 11% were infected with Trypanosoma cruzi and 2% were infected with T. rangeli.Conclusions/SignificanceTo date, only limited vector control efforts have been implemented. Together with recent reports of widespread sylvatic triatomine infestation and frequent post-intervention reinfestation, these results show that an estimated 100,000 people living in rural areas of southern Ecuador are at high risk for T. cruzi infection. Therefore, there is a need for a systematic, sustained, and monitored vector control intervention that is coupled with improvement of socio-economic conditions.

“…Despite the general consensus that Chagas disease is directly linked to poverty and to social determinants (DIAS 2001, BRICEÑO-LEÓN; MÉNDEZ GALVÁN 2007, SILVEIRA 2007, ROJAS DE ARIAS 2007, MANNE et al 2013, VENTURA-GARCIA et al 2013, social issues are scarcely approached in the specific literature, corresponding to less than 0,01% of the produced knowledge available on PubMed: social sciences research is a neglected area of investigation: the keyword "Chagas disease" retrieved 16,362 references and the cross match of "Chagas disease" and "social" or "Chagas disease" and "education" found, respectively, 235 and 175 references on May 10th, 2018. However, when dealing with clinical trials (BRASIL et al 2014) and translational research (CUNHA-NETO; CHEVILLARD 2014), scientists face directly social conditions of Chagas disease patients, as well as social interaction in interdisciplinary teams.…”

Interdisciplinary collaboration is essential to overcome complex problems in contemporaneity. Chagas disease challenges in Brazilian Amazon, implicates One Health interdisciplinary approaches and teams to integrate health of humans, animals and the environment, to foster earlier detection of this zoonotic disease and better prevention. We studied the interdisciplinary team, the logistic of its long term field work and the education processes emerging on a non-formal education environment of a Chagas disease Protocol conduced in Pará. An alarming situation: notified acute cases almost doubled in two years. Photographs were presented (iconographic approach) to qualitatively describe the experience of the interdisciplinary team. Five recommendations were proposed at the end of the study. Our observational study with the interdisciplinary team confirmed the conception that “in connecting the purity of science with the pragmatism of policy, the intangibles of trust, rapport, and even friendship can be more potent than logic and more compelling than evidence”.
