It is characterized by affect low-income and low educational-level populations, houses in precarious conditions, poor access to health services, drinking water and basic sanitation as well as living in conflict areas.

Objective: Identify through systematic review different prevention and control interventions for Chagas disease.

Methods: population or colectives studies written in english, spanish and portuguese with results related to health interventions during 201 0-2015 in Latin america were included. Information search was performed by using databases like Pubmed/Medline, LILACS, HINARI and cochrane as well as gray literature and official webpages from health ministries, PAHO and WHO. Two independent researchers reviewed and evaluated the quality of studies. From this, interventions and results were identified.

Results and discussion: in total, 193 papers were identified. From those, 118 were excluded and 59 remained for the reading. Identified interventions were classified into four categories: 1) vector control, 2) improvement of living conditions: housing and surroundings/environmental education, 3) knowledge of disease, attitudes, practices 4) identification of barriers, and proposal of alternatives for access to health services, diagnosis and timely treatment. Interventions execution should be done in articulated way among the four categories under the identification of implied social determinants.
