Assessment of Community Awareness and Screening of Chagas Disease in the Latin American Community of Greater New Orleans.

ABSTRACT: 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.

Project description:BackgroundChagas disease is a parasitic disease endemic to Latin America, but it has become a disease of global concern due to migration flows. Asymptomatic carriers may host the parasite for years, without knowing they are infected. The aim of this study is to assess prevalence of Chagas disease and evaluate the participants' level of knowledge between Latin American migrants attending a community-based screening campaign.MethodsThree community-based campaigns were performed in Alicante (Spain) in 2016, 2017 and 2018, including educational chats and blood tests for Trypanosoma cruzi serology. Participants completed a questionnaire assessing knowledge about the mechanisms of transmission, disease presentation, diagnosis, and treatment. People seropositive for T. cruzi underwent diagnostic confirmation by two different tests. Results were analyzed by multivariable logistic regression and expressed as adjusted odds ratios (aORs), adjusting for age, sex, and time in Spain.ResultsA total of 596 participants were included in the study; 17% were aged under 18 years. Prevalence in adults was 11% [54/496; 95% confidence interval (CI): 8.3-14.5%] versus 0% among children. All but one case were in Bolivians. Diagnosis was independently associated with having been born in Bolivia (aOR: 102, 95% CI: 13-781) and a primary school-level education (aOR: 2.40, 95% CI: 1.14-5.06). Of 54 people diagnosed with Chagas disease (most of whom were asymptomatic), 42 (77.7%) returned to the clinic at least once, and 24 (44.4%) received treatment. Multivariable analysis showed that coming from Argentina (aOR: 13, 95% CI: 1.61-1188) or Bolivia (aOR: 1.90, 95% CI: 1.19-3.39) and having received information about Chagas disease in Spain (aOR: 4.63, 95% CI: 2.54-8.97) were associated with a good level of knowledge on the disease. Having primary level studies (aOR: 0.59, 95% CI: 0.34-0.98) and coming from Ecuador (aOR: 4.63, 95% CI: 2.52-847) were independently associated with a lower level of knowledge.ConclusionsCommunity-based interventions are a good strategy for diagnosing neglected diseases such as Chagas disease in non-endemic countries and for identifying and treating infected, asymptomatic individuals.

Project description:INTRODUCTION:Dengue is an escalating public health concern in Latin American Countries with a dramatic increase of cases reported during the past decade. The objectives of this study were to identify and provide insights into current management and attitudes toward dengue and to understand attitudes to vaccination and current behaviors to prevent dengue in Mexico and Colombia. METHODS:This was a community-based, cross-sectional, descriptive study conducted in urban and rural areas in endemic and non-endemic regions. The interviews were conducted face-to-face using a structured questionnaire containing 58 questions. A quota sampling approach was used to obtain a nationally representative sample of the adult population. All data were weighted to correct for differences between the samples surveyed in each country relative to their general population. RESULTS:A total of 1978 participants completed the survey. Two percent and 10% of participants in Mexico and Colombia, respectively, had experienced dengue fever, with just under one-third of adults and almost two-thirds of their children hospitalized as a result of the illness. Awareness of dengue was similar in Colombia (76%) and Mexico (68%), with awareness higher in endemic regions than in non-endemic regions. Colombia had a higher proportion of participants (84%) who considered dengue to be a common disease in their country, compared with Mexico (56%). In Mexico and Colombia, 55% and 54% in endemic areas, and 28% and 46% in non-endemic areas believed that everyone was at risk of contracting dengue. In both countries, the most common action undertaken by participants to prevent dengue infection was removal of standing water. At least 70% of participants believe their government could do more to prevent dengue in their country. CONCLUSIONS:Dengue was identified as a severe and common disease in Mexico and Colombia. Most participants recognized the need to reduce the risk of dengue infection by removal of standing water. Awareness was similar in Colombia and Mexico.
