Determining the distribution of disease prevalence among heterogeneous populations at national scale is fundamental for epidemiology and public health. Here, we use a combination methods (spatial scan statistic, topological data analysis epidemic profile) to study measurable differences in malaria intensity by regions Colombia. This explores three main questions: What are Colombia where epidemic? endemic? associations exist between outbreaks Colombia? Plasmodium falciparum most prevalent...
Abstract As malaria control programmes concentrate their efforts towards elimination a better understanding of transmission patterns at fine spatial resolution units becomes necessary. Defining that consider heterogeneity, human movement and migration will help to set up achievable milestones guide the creation efficient operational administrative units. Using combination genetic epidemiological data we defined unit as area contributing 95% cases diagnosed catchment facility located in town...
Anthropogenic change has been associated with population growth, land use change, and changing economies. However, internal migration patterns armed conflicts are also key drivers of anthropogenic demographic processes. To better understand the processes this we explore spatial relationship between forced due to conflict socioeconomic factors in Colombia, a country which recent history 7 million migrants. In addition, remote sensing, Google Earth Engine, as well statistical analyses data...
Background The SARS-CoV-2 pandemic has forced health authorities across the world to take important decisions curtail its spread. Genomic epidemiology emerged as a valuable tool understand introductions and spread of virus in specific geographic location. Methodology/Principal findings Here, we report sequences 59 samples from inhabitants Colombian Amazonas department. viral genomes were distributed two robust clusters within distinct GISAID clades GH G. Spatial-temporal analyses revealed...
Migration to urban centres is among the most important forces in contemporary studies. In this paper, we study how demography and epidemic profile of a community are altered when they transition from living nomadic conditions forested environment peri-urban settlement city Amazon basin. We analyse demographic data with multilevel model understand individual community-level effects terms risk malarial infection. show that malaria becomes endemic population settles area city. also reproductive...
Colombia has had one of the largest numbers internally displaced populations in world and 2016 entered a period post-conflict. These socio-ecological geopolitical processes trends have increased migration people towards cities accordingly are affecting distribution occurrence tropical diseases its urban peri-urban areas. Studies suggested that anthropogenic phenomena such as urbanization scale according to size human regardless cultural context. But, other studies show health epidemics...
Aims: Malaria in the Amazon basin is persistently more prevalent among low density populations (1-4 people/km2). Describing malaria transmission small populations, such as ethnic minorities basin, living reserves groups that amount to 110-450 individuals, fundamental for implementation of adequate interventions. Here, we examine a context high prevalence population Nükak ethnicity (ethnic group n=400-650 study group, n=108 individuals) peri-urban area city with 35,000 inhabitants basin....
This study investigates the intricate relationship between Venezuelan migration and urban growth in Colombia from 2018 to 2021. The employs remote sensing data social network metrics uncover patterns their impact on expansion. methodology consists of three stages. Firstly, nighttime satellite imagery is used analyze year-over-year Colombia. Secondly, estimates migration, overcoming challenges underreporting informal border crossings. Lastly, an econometric analysis explores quantitative link...
La tecnología aplicada al uso de grandes datos ha sido una herramienta importante para proveer información necesaria dar respuestas a los retos salud pública ante la pandemia COVID-19, y en Colombia no excepción. En este documento se analizan dos insumos analítica (rastreo digital contactos análisis agregado movilidad, ambos basados telefonía celular) sobre cuales han tomado medidas púbica el país latinoamericano como, por ejemplo, determinar zonas control diferencial dentro ciudad, rastreo...

Anthropogenic change is generally associated with population growth, land use change, and changing economies. However, internal migration patterns armed conflicts can also be key drivers behind these anthropogenic demographic processes. To better understand this dynamic, we explore the spatial relationship between forced due to conflict factors in Colombia; a country recent history of 7 million migrants. First, spatiotemporally analyzed from using remote sensing measure during 1984-2018 then...

These socio-political processes trends have increased migration people towards cities accordingly are affecting distribution occurrence tropical diseases its urban peri-urban areas. Studies suggested that many human phenomena such as urbanization scale according to size regardless cultural context. But other studies show health epidemics malarial immunodeficiency...
Abstract Literature on social networks and elections has focused predicting electoral outcomes rather than understanding how the discussions between users evolve over time. As a result, most studies focus single election few comparative exist. In this article, framework to analyze Twitter conversations about candidates is proposed. Using DeGroot’s consensus model (an assumption that all are attempting persuade others talk candidate), useful identify structure strength of connections mention...
Abstract After the initial year of pandemic (2020), a need for Non-Pharmaceutical Interventions (NPIs) that did not imply lockdowns became evident, particularly in locations where human mobility was greatly restricted like South America. In this research, we propose multidisciplinary framework to combine findings from diverse academic fields (epidemiology, public health, urban studies, molecular biology) inform decision making health. Furthermore, designed and implemented NPIs minimized...
Abstract Technological developments in media and communications such as press, radio, television have disrupted electoral processes reshaped political landscapes. Similarly, the development of surveys enabled social sciences to study voting measure consensus a population prior democratic elections. Literature on networks elections has focused predicting outcomes rather than understanding how discussions between users evolve over time. As result most studies focus single election few...
