Urban outbreak of acute orally acquired Chagas disease in Táchira, Venezuela

Urban outbreak of acute orally acquired Chagas disease in Táchira, Venezuela

Acute orally acquired Chagas disease (AOACD) has emerged as a significant threat in some countries of South America [1,2]. Until March 2013, at least four have reported outbreaks of acute orally acquired Chagas disease, specifically Brazil [3], Venezuela [4], Colombia [5] and Bolivia [6]. Outbreaks are also likely occurring in Argentina and Ecuador, according to some old reports [2]. In Venezuela, there have been at least three well-known epidemiological reports of AOACD, the first in 2007 at Caracas (Chacao) [4], the second in 2009 at Vargas [7] and the third in 2010 at Caracas (Antimano) [8]. A common feature of these outbreaks is that they have  affected predominantly children and have led to a high fatality rate among confirmed cases. Reports describing the investigation of these outbreaks are of high scientific and  epidemiological significance; however, information on only the first outbreak has been published [4]. For  these reasons we report the findings of the fourth outbreak of AOACD that occurred in Venezuela, in Táchira state (Figure).
