“…From these pioneering studies on the relationship between Chagas disease and PHC, it was evident that there was a failure in the identifi cation of those aff ected with Chagas disease, be it acute, chronic symptomatic, or in the indeterminate phase, when the users entered the health care system, that is, PHC, the service which supplies the majority of care for neglected diseases, and that, therefore, should be the fi rst detection site for those aff ected. This failure is found throughout the health care system, from the moment when the health professional should focus attention on the individual, and stresses the importance of a better approach and interpersonal relationship, as the patient, when looking for the health facility, is found to be most fragile and often has diffi culties in reporting their complaints/symptoms clearly [8,9]. Furthermore, this failure to identify diseased individuals may also be related to the lack of knowledge of health professionals about the epidemiology of the disease, which makes more detailed interviews diffi cult, and involves not only the "diseased individual", but also encompasses the environment which that individual inhabits (i.e., whether they live in an endemic area).…”
