Knowledge and experiences of Chagas disease in Bolivian women living in Spain: a qualitative study.

BACKGROUND

In 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.

OBJECTIVE

The 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.

DESIGN

Qualitative study based on semi-structured interviews, triangular groups, and field notes.

PARTICIPANTS

Fourteen Bolivian women with CD living in Madrid.

RESULTS

The 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.

CONCLUSIONS

Disease 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.
