I believe that it is imperative that the physician treating the patient knows the living conditions, SES and working environment for accurate diagnosis of disease. Per the article, we know that in Costa Rica Chagas disease is common and that in areas that have a lot of vegetation or forest area are even more likely to have these kissing bugs. People who live in these areas are most likely of lower SES and probably work in fields or farming causing them to be even more likely to be exposed to the kissing bug. Undocumented workers are getting paid much less then their counterparts and therefore wouldn't be able to afford decent housing and have to live in these forests or on the land that they work which is near the forest. These living conditions with dirt floors, gaps in the roof or walls, and lack of nets for bugs make people more susceptible to being bit.
