It is a very interesting study carried out by some of the best experts on Chagas disease in Spain. The data collected and the methodology used are the most appropriate.
The study is notable for the high percentage of infected people. This may be closely related to the area of the country of origin where these people live, for example, rural areas with a high prevalence of the vector of this disease, which are the kissing bugs or vinchucas. So there may be a bias if these patients come from these types of areas.
I believe that the positive aspect of the study is to initiate screening in patients who come from endemic areas of the disease, since it is not only transmitted by the vector (not present in Spain) but also by blood, for example, through transfusions.
