Trypanosoma cruzi is the causative agent of Chagas disease. Due to its genetic diversity has been classified into six Discrete Typing Units (DTUs) in association with transmission cycles. In Colombia, natural T. infection detected 15 triatomine species. There scarce information regarding rates, DTUs and feeding preferences secondary vectors. Therefore, aim this study was determine parasite DTU, ecotopes, insect stages, geographical location bug across different species.A total 245 insects...
Introducción. Las enfermedades transmitidas por vectores representan más de 17 % todas las infecciosas y causan anualmente un millón defunciones a nivel mundial. En Colombia, la malaria, el dengue, enfermedad Chagas leishmaniasis son condiciones endemoepidémicas persistentes.Objetivo. Determinar comportamiento epidemiológico en zonas urbanas rurales Colombia entre 1990 2016.Materiales métodos. Se hizo estudio descriptivo del principales 2016, con información proveniente fuentes oficiales...
Oral transmission of Trypanosoma cruzi has gained relevance because its association with high morbidity and lethality rates. This route is responsible for maintaining the infection parasite in sylvatic cycles, human cases have been associated mainly consumption food contaminated triatomine feces or didelphid secretions. Several ecological changes allow intrusion reservoirs triatomines to domestic environments subsequent contamination. Here, high-resolution molecular tools were used detect...
WHO's 2020 milestones for Chagas disease include having all endemic Latin American countries certified with no intradomiciliary Trypanosoma cruzi transmission, and infected patients under care. Evaluating the variation in historical exposure to infection is crucial assessing progress understanding priorities achieve these milestones.Focusing on Colombia, available age-structured serological surveys (undertaken between 1995 2014) were searched compiled. A total of 109 serosurveys found,...
Chagas disease (CD) is transmitted by vectors but can also be orally through contaminated food, drinks, or meat. The One Health perspective aims to understand the complex interaction between human, animal, and environmental health in controlling disease. This study analyzed risk factors drew lessons from past outbreaks of CD develop effective preventive strategies.
Introduction: Vector-borne diseases account for more than 17% of all infectious and annually they cause one million deaths worldwide. In Colombia, malaria, dengue, Chagas disease, leishmaniasis are persistent endemo-epidemic events.Objective: To determine the behavior transmission scenarios vector-borne in Colombia between 1990 2016.Materials methods: We conducted a descriptive study on epidemiological main 2016 based information from official secondary sources.Results: During period, there...
Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In Americas, CD creates greatest burden in disability-adjusted life years of any parasitic infection. Colombia, 437 000 T. whom 131 suffer from cardiomyopathy. Colombia's annual costs for treating patients advanced reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development cardiomyopathy-and just 30 per patient-fewer than 1%...
Background Tegumentary Leishmaniasis (TL) is a neglected disease with worldwide distribution and considered public health problem, especially in Latin America. In Colombia, the governmental epidemiological surveillance system (SIVIGILA) responsible for collecting information on presentation of cases TL from each municipalities departments. absence study compiling analyzing currently available metadata this describes geospatial-temporal identifies regions country which prevention measures...
Chagas disease (CD) affects over six million people and is a leading cause of heart failure in the Americas. Few are able to access diagnosis treatment for CD, resulting missed opportunity prevent morbimortality. Integration testing with primary healthcare level key step ensuring affected receive timely antitrypansomal therapy, which increasing evidence shows can chronic complications from halt congenital transmission. This article describes three collaborative projects focused on CD through...
This study seeks to address the critical knowledge gap surrounding acute phase of Chagas disease in Colombia, with a specific focus on cases reported 2019. The is pivotal period for intervention, yet it remains poorly understood, particularly regions where oral transmission presumed be significant factor. By analyzing these recent cases, our research aims provide deeper understanding dynamics during its Colombia essential not only improving management and treatment strategies but also...
Chagas disease affects over six million people, but less than 1% are diagnosed and treated. Complicated diagnostic processes a major barrier. Colombia's previous algorithm, using in-house tests, was difficult to scale up, creating significant access barriers for patients. A new algorithm commercially manufactured immunoassays would potentially improve access, these tests' performance in Colombian patients with is not well known.We assessed seven available assays. Samples (n=501), 93.8%...
La transmisión congénita de la enfermedad Chagas ha sido poco estudiada en Colombia y existen pocos procedimientos rutinarios el sistema salud para manejo esta enfermedad. Por ello se desarrolló un consenso expertos dirigido a generar recomendaciones diagnóstico tratamiento congénito orientación mujeres edad fértil. Con ese propósito realizó una búsqueda extensiva literatura, empleando combinación términos MeSH (Chagas, congénito, prevención, control, diagnóstico, embarazo) reflejar estado...
Colombia has one of the largest burdens Chagas disease globally, with about 438,000 people affected according to 2015 estimates. Despite this, < 1% population had access diagnosis and treatment. A patient-centered roadmap for was developed from onwards address barriers increase diagnostic therapeutic coverage implemented in five municipalities where is endemic. The mean number tested per year increased 37 before project 262 following implementation, average days between medical order...
In determining the possible influence of climate change, it is important to understand temporal and spatial variability in streamflow response for diverse zones. Thus, aim this study was determine presence changes annual maximum peak flow two zones Chile over past few decades. A general analysis, a flood frequency analysis trend were used such between 1975 2008 semi-arid (29°S–32°S) temperate (36°S–38°S) climatic zone. The historic maxima, minima mean flows, as well decadal flow, compared...
Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected human disease. It endemic to Americas and estimated have an economic impact, including lost productivity disability, of 7 billion dollars per year on average.To assess vulnerability vector-borne transmission T. cruzi in domiciliary environments within area undergoing vector interruption Colombia.Multi-criteria decision analysis [preference ranking method for enrichment evaluation (PROMETHEE) geometrical...
Sediment production and transport in a basin are generally function of the degree soil protection, normally represented by plant cover. In this study, two basins located at similar latitudes but with different hydrological regimens covers were studied, one pluvial regimen forest plantations (Purapel) another pluvio-nival native (Ñuble). For purpose, sediment yield was analyzed both drainage areas using Mann-Kendall statistical test. Both showed larger amounts during winter months. addition,...
Objective - This study presents an overview of the development network for knowledge management, research, and innovation in malaria (malaria network). With a focus on organizational factors that influenced its formation, aims to shed light broader contribute effective disease prevention control efforts by examining contextual elements shaped network. Materials methods The employed mixed-inductive approach, with qualitative core quantitative complement. Intentional sampling was used...
