Abstract
Several cases of acute Chagas disease (ACD) have been reported in the Peruvian Amazon basin. 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). 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. All cases reported were isolated cases. We report a new focus of ACD in indigenous populations.

Summary
The present study comprises a review of the investigation sheets and clinical files of the ACD cases reported. The parents and family relatives of the patients were interviewed with the help of a translator from the community, and serum samples were obtained for T. cruzi[5] detection. Blood samples were obtained according to the methods described elsewhere[5,8], and serum samples were evaluated to detect anti-T. cruzi IgG antibodies with Chagatest ELISA recombinant v. 30, Wiener Lab®, and by indirect immunofluorescence (IIF) with a diagnostic titer value of 1:32 When both tests were reactive was a patient considered seropositive for T. cruzi infection. Clinic and epidemiologic aspects of the identified ACD cases (Table 1) and the results of the investigation of collateral cases are presented
