Purpose
Chagas disease is a systemic chronic parasitic infection by
Trypanosoma cruzi
endemic in Latin America. Migration of women of childbearing age from Latin America to developed countries may spread the disease to non-endemic areas through vertical transmission.
Methods
Prospective study of seroprevalence of
T. cruzi
infection in immigrant Latin American pregnant women during a 5-year period (from 2006 to 2010) in Spain.
Results
Seven out of 545 participants were seropositive for
T. cruzi
[prevalence 1.28%, 95% confidence interval (CI) 0.06–2.56]. Four (57%) were from Bolivia and three (43.%) from Paraguay. The seroprevalence in pregnant women from Bolivia was 10.26% (95% CI 4.06–23.58) and in participants from Paraguay was 6.52% (95% CI 2.24–17.5). No congenital transmission occurred.
Conclusions
Seroprevalence of
T. cruzi
infection in Latin American pregnant women coming from Bolivia and Paraguay is high. Those women should be screened for
T. cruzi
to control mother-to-child transmission in non-endemic areas.
