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...

Background Chagas disease, transmitted domestically by triatomine bugs, is the most important vector-borne disease in Latin America. The association between infestation and housing characteristics was investigated based on a standardized survey 41 971 houses 15 Departments Colombia. Methods Multivariate logistic regression used to test for associations of two highly correlated measures (householders reporting having seen triatomines inside house, sending team), with household-level risk...

Introduction. Chagas' disease is endemic in 21 countries of South and Central America, including Colombia, where 700,000 to 1.2 million persons are infected eight millions at risk. In areas, chronic cases predominant. However, recent years, increasing reports acute oral transmission have appeared.Objective. An outbreak was verified the municipality Turbo (Antioquia), most probable cause determined order establish prevention control measures.Materials methods. A descriptive study done. search...

Ecological niche modeling of Triatominae bugs allow us to establish the local risk transmission parasite Trypanosoma cruzi, which causes Chagas disease . This information could help guide health authority recommendations on infection monitoring, prevention, and control. In this study, we estimated geographic distribution triatomine species in Colombia identified relationship between landscape structure climatic factors influencing their occurrence. A total 2451 records 4 ( Panstrongylus...

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,...

Abstract Chagas disease remains a major neglected in Colombia. We aimed to characterize Trypanosoma cruzi transmission networks the Sierra Nevada de Santa Marta (SNSM) region, shed light on ecology and help optimize control strategies. Triatomines were collected rural communities analyzed for blood feeding sources, parasite diversity gut microbiota composition through metagenomic deep sequencing approach. Triatoma dimidiata predominated, followed by Rhodnius prolixus, maculata, pallescens,...

To determine the incidence of dengue infection, we established active surveillance febrile episodes in a cohort schoolchildren from three schools Medellin, Colombia. We followed 2,379 2010 and 1,840 these children following year. During follow-up time, 264 displayed 297 episodes; these, 23 (7.7%) were caused by acute infection. All four serotypes found, all cases mild. The most common symptoms compared with those other illness asthenia (96% versus 87%), anorexia (78% 57%), rhinorrhea (65.2%...

Triatoma dimidiata (Hemiptera: Reduviidae) is a secondary vector of Trypanosoma cruzi in Colombia and represents an important epidemiological risk mainly the central oriental regions country where it occupies sylvatic, peridomestic, intradomestic ecotopes, because this complex distribution, its distribution abundance could be conditioned by environmental factors. In work, we explored relationship between T. factors northwest, northeast, zones developed predictive models infestation country....

Introduction. Triatoma dimidiata is the second most important vector of Chagas disease in Colombia after Rhodnius prolixus. Population genetic studies are essential for adequate design and implementation control surveillance strategies.Objective. The level variability population differentiation was surveyed among three Colombian populations T. from different geographic locations ecotopes, using ND4 mitochondrial gene.Materials methods. Genetic comparison made between two wild La Guajira...

Irrigation schemes and dams have posed a great concern on public health systems of several countries, mainly in the tropics. The focus present review is to elucidate different ways how these human interventions may an effect population dynamics anopheline mosquitoes hence, local malaria transmission patterns be changed. We discuss studies within three main tropical sub-tropical regions (namely Africa, Asia Pacific Americas). Factors such as pre-human impact epidemiological patterns, control...

In Colombia, the main vectors of Trypanosoma cruzi , causative agent Chagas disease, are Rhodnius prolixus and Triatoma dimidiata . T. is present in east region Colombia as domestic, peridomestic, sylvatic populations, resulting difficulties for its control. A cost-effective way to prioritize houses treatment stratify based on risk factors. this study, factors were evaluated potential associations with domicile infestation There was an increased likelihood domestic associated presence mixed...

Ecoepidemiological scenarios for Chagas disease transmission are complex, so vector control measures to decrease human–vector contact and prevent infection difficult implement in all geographic contexts. This study assessed the abundance patterns of two species disease: Triatoma maculata (Erichson, 1848) Rhodnius pallescens (Barber, 1932) Latin America. We modeled their potential distribution using maximum entropy algorithm implemented Maxent calculated distances niche centroid by fitting a...

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, practices about determined the infestation levels of Aedes aegypti one Brazilian four Colombian communities. Results The surveys show knowledge vector, but little diagnosis, prognosis, treatment. Vector indices to have good relative control, while Colombia presents a high transmission risk. Conclusions Given...

Aedes albopictus is widely distributed around the world. Its introduction to Americas occurred in 1985 and it considered a potential vector of dengue viruses one principal vectors chikungunya virus. In Colombia, this species was reported for first time Leticia (Amazonas) 1998, followed by Buenaventura (Valle del Cauca) 2001, Barrancabermeja (Santander) 2010, Medellín (Antioquia) 2011. So far, has been ten departments country. Objective: To report finding A. city Istmina, Chocó, its...

Mother-to-child transmission of Chagas disease (CD) has become a relevant problem in both endemic and non-endemic areas.Description the CUIDA Project - Communities United for Innovation, Development Attention disease'.Through innovative strategic research, this project will provide improved diagnostic treatment options as well replicable implementation models that are adaptable to different contexts.By integrating test, treat care actions CD into primary health practices, burden on people...

Abstract During the last two decades, world has witnessed emergence and re-emergence of arthropod-borne viruses, better known as arboviruses. The close contact between sylvatic, rural peri-urban vector species humans been mainly determined by environment-modifying human activity. resulting interactions have led to multiple dead-end host infections allowed sylvatic arboviruses eventually adapt new vectors hosts, contributing establishment urban transmission cycles some viruses with enormous...
