Clinical and epidemiological characteristics of cases of acute Chagas disease in the Peruvian amazon basin, 2009-2016

Acute Chagas disease (ACD) cases are reported sporadically in Peru. In this report we describe the clinical and epidemiological characteristics of eight new ACD cases detected by the surveillance system in the Amazon basin, between 2009 and 2016. The average age was 12,7 ±13.7 years, range between 1 to 44 years and 4/8 cases were men. One case was associated with acute diarrheal disease, another with Leptospirosis, and two with urinary tract infection. The global case fatality-rate was 12.5% (1/8). Late detection is a frequent characteristic related with low diagnostic suspicion in patients with a history of fever. The TcI and TcIV lineage was identified as the etiological agent of Chagas disease. Eight new cases of ACDs are reported, of which seven were children.
