Cribado ampliado de Trypanosoma cruzi en la descendencia de mujeres infectadas en la zona metropolitana norte de Barcelona, Cataluña (España), 2005-2016

Offspring of T. cruzi-seropositive women showed a high rate of seropositivity. The prevalence of vertical transmission is also remarkably high but comparable to that obtained in other European studies. The main source of loss was non-accessible women. It is reasonable to formaly include extensive, familiar, serological assessment in Chagas screening guidelines. In order to avoid losses, any eventual screening should be implemented at the time of the maternal diagnosis.
