  We use mobile phone records for the analysis of mobility patterns and the
detection of possible risk zones of Chagas disease in two Latin American
countries. We show that geolocalized call records are rich in social and
individual information, which can be used to infer whether an individual has
lived in an endemic area. We present two case studies, in Argentina and in
Mexico, using data provided by mobile phone companies from each country. The
risk maps that we generate can be used by health campaign managers to target
specific areas and allocate resources more effectively.
