Abstract. Knowledge of the prevalence and risk factors associated with maternal infection is the first step to develop a surveillance system for congenital transmission of Chagas disease. We conducted a cross-sectional study in Casanare, a disease-endemic area in Colombia. A total of 982 patients were enrolled in the study. A global prevalence of Trypanosoma cruzi infection of 4.0% (95% confidence interval [CI] = 2.8-5.3%) was found. Multivariate analysis showed that the most important risk-associated factors were age 29 years (adjusted odds ratio [aOR] = 3.4, 95% CI = 0.9-12.4), rural residency (aOR = 2.2, 95% CI = 1.0-4.6), low education level (aOR = 10.2, 95% CI = 1.6-82.7), and previous knowledge of the vector (aOR = 2.2, 95% CI = 1.0-4.9). Relatives and siblings of infected mothers showed a prevalence of 9.3%. These findings may help physicians to investigate congenital cases, screen Chagas disease in siblings and relatives, and provide early treatment to prevent the chronic complications of Chagas disease.

Objective: To identify the demands for the psychosocial care of vulnerable communities in the Vale do Itajaí, Santa Catarina Methods: Qualitative research, multiple case study, through narrative interviews with health professionals in three municipalities, from January to May 2018. The analysis of the narratives followed a formal analysis of the text, structural description of the content, analytical abstraction, analysis of knowledge, and contrastive comparison. Results: The described categories were: Meanings of the demands for support before the flood; Meanings of the demands during the occurrence of the disaster; Meanings of demands after the flood: psychosocial care; Meanings of the demands for monitoring the territory after the disaster. Conclusion: The identification of demands for mental health care after the disaster occurs through the search for health services, specific symptoms, and consequences of adapting to the recovery phase, such as migratory processes and temporary housing. The research contributes to the culture of care with a multiprofessional perspective in health care for the population affected by disasters.
