摘要
Chagas disease is a public health problem in the Americas, from the southern United States (USA) to Argentina. In the USA, less than 1% of domestic cases have been identified and less than 0.3% of total cases have received treatment. Little is known about affected immigrant Latin American communities. A prospective study was conducted to assess knowledge about Chagas disease among the Latin American community living in the Greater New Orleans area. Participants answered a baseline questionnaire, viewed a short educational video presentation, completed a post-presentation questionnaire, and were screened with an FDA-approved blood rapid diagnostic test (RDT). A total of 154 participants from 18 Latin American countries (n = 138) and the USA (n = 16) were enrolled and screened for Trypanosoma cruzi infection. At baseline, 57% of the participants knew that Chagas disease is transmitted through an insect vector, and 26% recognized images of the vector. Following the administration of an educational intervention, the participants' knowledge regarding vector transmission increased to 91% and 35% of participants were able to successfully identify images of the vector. Five participants screened positive for T. cruzi infection, indicating a 3.24% [95%CI: 1.1-7.5%] prevalence of Trypanosoma cruzi infection within the Latin American community of the New Orleans area. Results highlight the urgent need for improving access to education and diagnostics of Chagas disease.
