Our objective was to determine the frequency of zika (ZIKV), chikungunya (CHIKV) and dengue (DENV) virus coinfection describe mortality cases that occurred during epidemiologic surveillance ZIKV epidemic in Colombia. We analysed all suspected infection were reported National Institute Health (October 2015-December 2016). DENV, CHIKV RNA detected serum or tissue samples using polymerase chain reaction assay. Medical records fatal reviewed. identified 23 871 processed. The viral agents 439...
Abstract We investigated 2 fatal cases of Rocky Mountain spotted fever that occurred in 2003 and 2004 near the same locality Colombia where disease was first reported 1930s. A retrospective serosurvey febrile patients showed >21% serum samples had antibodies against group rickettsiae.
Summary Chagas disease is an endemic of the American continent caused by Trypanosoma cruzi and divided into six discrete typing units (TcI – Tc VI ). Nearly 10 million people harbour infection representing a serious issue in public health. Epidemiological surveillance allowed us to detect bat‐related T. genotype (henceforth named TcBat) 5‐year‐old female living forest area northwestern Colombia. Molecular tools determined mixed I TcBat genotypes. This represents first report humans;...
We report clinical features and histopathological findings in fatal cases with dengue (DENV) chikungunya (CHIKV) co-infection identified at the Colombian National Institute of Health between September 2014 October 2015. Seven such were documented. Dengue serotype 2 virus was six cases. All patients adults comorbidities present four. Fever, arthralgia or myalgia all The frequency rash, haemorrhage, oedema, gastrointestinal symptoms variable. Laboratory as thrombocytopenia, renal failure,...
Background Acute undifferentiated febrile illness is a common challenge for clinicians, especially in tropical and subtropical countries. Incorrect or delayed diagnosis of patients may result medical complications preventable deaths. Common causes acute Colombia include leptospirosis, rickettsioses, dengue fever, malaria, chikungunya, Zika virus infection. In this study, we described the postmortem reported as suspected cases leptospirosis through national surveillance Colombia, 2016–2019....
We report the results of pathologic examinations 2 fetuses from women in Colombia with Zika virus infection during pregnancy that revealed severe central nervous system defects and potential associated abnormalities eye, spleen, placenta. Amniotic fluid tissues multiple fetal organs tested positive for virus.
Abstract Background Children are considered a potentially vulnerable population for Zika virus infection. However, data on paediatric infection sparse. Methods We analysed from Colombia's national surveillance system during the 2015–2016 outbreak patients meeting clinical case definition of disease ( ZVD ) among children aged 1 month to 18 years estimate incidence by demographic characteristics and characterize occurrence selected complications. Results Between August 14, 2015, May 28, 2016,...
Objetivos En marzo de 2008 ocurrió en el municipio Santander Quilichao- Cauca, Colombia, un brote rabia origen silvestre con 2 víctimas humanas. El presente artículo apunta a describir las técnicas diagnósticas laboratorio, acciones investigación campo y control foco empleadas, su significado epidemiológico e implicaciones salud pública. Métodos La se diagnosticó por inmunofluorescencia directa, prueba biológica ratón, histopatología inmunohistoquímica, tipificó utilizando anticuerpos...
To calculate triatomine infestation indices in indigenous communities Colombia.A descriptive study was carried out 19 Valledupar Municipality, Cesar Department, Colombia. During June to December, 2007, triatromine bugs were collected from their resting places households. Taxonomic identification made according the keys by Lent & Wygodzinsky. An infection process animal model and isozyme analysis of feces performed.Rhodnius prolixus showed a density index 154.7%, for Triatoma dimidiata...
SUMMARY Chagas disease is a complex zoonosis that affects around 8 million people worldwide. This pathology caused by Trypanosoma cruzi , kinetoplastid parasite shows tremendous genetic diversity evinced in six distinct Discrete Typing Units (TcI-TcVI) including recent genotype named as TcBat and associated with anthropogenic bats. TcI presents broad geographical distribution has been chronic cardiomyopathy. Recent phylogenetic studies suggest the existence of two genotypes (Domestic (TcI...
According to the World Health Organization, 98% of fatal dengue cases can be prevented; however, endemic countries such as Colombia have recorded higher case fatality rates during recent epidemics. We aimed identify predictors mortality that allow risk stratification and timely intervention in patients with dengue. conducted a hospital-based, case-control (1:2) study two areas (2009-2015). Fatal were defined having either 1) positive serological test (IgM or NS1), 2) virological (RT-PCR...
Heart transplant is a therapeutic option in the treatment of chagasic cardiomyopathy. For early detection Chagas reactivation cases, use PCR tests using endomyocardial biopsies has been proposed. Development an animal model will be first step evaluating applicability this approach.PCR based on TcH2AF-R and S35-S36 primers were evaluated for T. cruzi heart tissue mice experimentally infected with parasite.Two groups ICR 15 10 individuals by intraperitoneal injection 0.3 ml PBS containing 1 x...
A workshop was developed to determine a roadmap for the implementation of smart grids in Colombia. More than 125 participants from different companies, universities, government, etc. took part this process. According with previously established focus areas, workgroups voted two matrices: Pertinence and Relevance. The results were analyzed construct an initial Colombian electrical sector three phases. This road map is key element organize efforts towards Smart Grid implementation. Among other...
Introduction. During months May to July 2004, a rabies outbreak in the Embera community of Birrinchao, Purricha river basin department Chocó was reported with 14 human deaths. Another January 2005 black communities Pató and Nauca neighboring municipality Alto Baudó 3 Objectives. To describe largest outbreaks transmitted by vampire bats Colombia date. diagnostic laboratory techniques used, theactivities undertaken for control area. discuss epidemiologic significance public health implications...
This paper describes the design and implementation of National Laboratory Smart Grids in University Campus (LAB+i) with real-time integration electricity, water and/or gas systems through six layers that allow to make measurement a process, local or remote communication order be integrated supervision management system. Likewise following LAB+i, information processes, decision making, modeling processes enable development optimum efficiency productivity applications are made. LAB+i is...
Introduction. An urban rabies outbreak occurred in the District of Santa Marta between April 2006 and January 2008, which resulted deaths 4 humans 28 dogs.Objectives. Three objectives were entertained—first, diagnostic laboratory techniques described as well control actions taken; second, impact anti-rabies dog vaccination was assessed terms neutralizing antibody seroconversion; third, epidemiological significance public health implications examined.Materials methods. Rabies diagnosis...
The electrical system is presented as a large "energy transformation engine" that takes different forms of energy to convert it given its wide usage and increasing demand in the future. As result new technologies reliability electricity supply will be increased dramatically, something useful for society depend more on this source energy. This paper explores evolution by considering example Colombian Power system. current situation analyzed future scenario formulated, leading comparison main...
Abstract Aims: The 2009 H1N1 pandemic illustrated the higher morbidity and mortality from viral infections in peripartum women. We describe clinical features of women who recently died Colombia. Methods: This is a case series study that was gathered through retrospective record review all maternal deaths country. national database confirmed pregnancy up to 42 days after delivery reviewed during season 2009.
