Abstract

CABRERA, Rufino et al. New focus of active transmission of Chagas disease in indigenous populations in the Peruvian Amazon basin. Rev. Soc. Bras. Med. Trop. [online]. 2013, vol.46, n.3, pp.367-372. ISSN 0037-8682.  http://dx.doi.org/10.1590/0037-8682-1195-2013.

Introduction

Several cases of acute Chagas disease (ACD) have been reported in the Peruvian Amazon basin.

Methods

The objective was to describe and investigate 6 ACD cases in children from indigenous Amazon communities in the province of Datem del Marañón in Loreto department (2006-2010).

Results

The mean age was 3.6 years. All patients had fever, 4/6 hepatomegaly, 2/6 splenomegaly, and 5/6 had trypomastigotes of Trypanosoma cruzi on thick smears. The fatality rate was 33.3%. Rhodnius pictipes and Rhodnius robustus adults were found inside the homes and in the peri-domiciles.

Conclusions

All cases reported were isolated cases. We report a new focus of ACD in indigenous populations.
