  Chagas disease is a neglected disease, and information about its geographical
spread is very scarse. We analyze here mobility and calling patterns in order
to identify potential risk zones for the disease, by using public health
information and mobile phone records. Geolocalized call records are rich in
social and mobility information, which can be used to infer whether an
individual has lived in an endemic area. We present two case studies in Latin
American countries. Our objective is to generate risk maps which can be used by
public health campaign managers to prioritize detection campaigns and target
specific areas. Finally, we analyze the value of mobile phone data to infer
long-term migrations, which play a crucial role in the geographical spread of
Chagas disease.
