Seroprevalence of Trypanosoma cruzi Infection in French Guiana Christine Aznar; Guy La Ruche; Stéphane Laventure; Bernard Carme; Pascale Liegeard & Mireille Hontebeyrie Abstract A survey was carried out on 1487 individuals to assess the seroprevalence of Trypanosoma cruzi infection in French Guiana. The overall prevalence of T. cruzi specific IgG was 0.5%. In multivariate analysis, residence in areas where housing is favorable for the presence of triatomine bugs was the only factor associated with the presence of T. cruzi antibodies. These results have implications for public health since blood donors are not routinely screened for T. cruzi infection in French Guiana.
