May support targeted Chagas screening in at-risk pregnancies; leaves open prospective evaluation of transmission prevention.
Cross-Sectional (n=1,975)

Routine prenatal screening for Chagas disease in Latin American immigrants in non-endemic areas reveals a significant prevalence of infection and enables early detection and treatment of congenital transmission.
Barona-Vilar et al. (2011) conducted a cross-sectional in Trypanosoma cruzi infection (Chagas disease) (n=1,975). Origin from Chagas-endemic Latin American countries was evaluated on Prevalence of Trypanosoma cruzi infection (95% CI 10.0-12.9). The overall seroprevalence of Trypanosoma cruzi infection in pregnant women from endemic Latin American countries was 11.4%, with a congenital transmission rate of 3.7% among infected Bolivian mothers.
