The prevalence of Trypanosoma cruzi was estimated in a sample of 995 people. The prevalence adjusted on age was 51.2% and was proportionally related to age. We also observed a very significant cline from the south to the north of the locality, where the prevalence ranged from 40 to 80%. In children younger than 11 years, the prevalence was 21.5%, which confirmed the importance of residual vector transmission despite several years of vector control. Among women of procreation age, the prevalence was 63.9%, resulting in a high risk of congenital transmission. The control of the disease requires an increase in vector control and improvement of dwellings before considering children's treatment with trypanocide. specialized Chagas disease Trypanosoma cruzi Epidemiology Transmission Control Bolivia 052 102 6 578-584 2008 0035-9203 https://www.documentation.ird.fr/hor/fdi:010042686 10.1016/j.trstmh.2008.03.008 0035-9203 [F B010042686] https://www.documentation.ird.fr/hor/fdi:010042686 https://www.documentation.ird.fr/intranet/publi/2008/08/010042686.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-09-19 2017-08-23 fdi:010042686 fre
