Abstract Many studies have used mobile device location data to model SARS-CoV-2 dynamics, yet relationships between mobility behavior and endemic respiratory pathogens are less understood. We studied the effects of population on transmission 17 viruses in Seattle over a 4-year period, 2018-2022. Before 2020, visits schools daycares, within-city mixing, visitor inflow preceded or coincided with seasonal outbreaks viruses. Pathogen circulation dropped substantially after initiation COVID-19...
The coronavirus disease 2019 (COVID-19) pandemic is dominated by variant viruses; the resulting impact on severity remains unclear. Using a retrospective cohort study, we assessed hospitalization risk following infection with 7 severe acute respiratory syndrome 2 (SARS-CoV-2) variants.Our study includes individuals positive SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) in Washington Disease Reporting System available viral genome data, from 1 December 2020 to 14 January...
Structured Abstract Background The urgent need for massively scaled clinical testing SARS-CoV-2, along with global shortages of critical reagents and supplies, has necessitated development streamlined laboratory protocols. Conventional nucleic acid SARS-CoV-2 involves collection a specimen nasopharyngeal swab in transport medium, extraction, quantitative reverse transcription PCR (RT-qPCR) (1). As across the world, supply chain buckled, rendering materials scarce (2). To address shortages,...
SARS-CoV-2 transmission is largely driven by heterogeneous dynamics at a local scale, leaving health departments to design interventions with limited information. We analyzed genomes sampled between February 2020 and March 2022 jointly epidemiological cell phone mobility data investigate fine scale spatiotemporal in King County, Washington, diverse, metropolitan US county. applied an approximate structured coalescent approach model within North County South alongside the rate of outside...
Abstract Background With the ending of public health emergency and changes in testing landscape, less is known about SARS-CoV-2 incidence community than earlier pandemic. Our goal was to describe among individuals 6 months 49 years age enrolled Cascadia prospective cohort study Oregon Washington, USA, by age, sex, COVID-19 vaccination status. Covid-like illness (CLI) status definitions Methods We included participants July 1, 2022 – March 31, 2024. collected weekly nasal swabs surveys from...
Abstract Background Congregate homeless shelters are disproportionately affected by infectious disease outbreaks. Although outbreaks of SARS-CoV-2 and influenza viruses have been reported in shelters, there minimal data describing enterovirus transmission among people experiencing homelessness.Figure 1. Nasal swab specimens detection October 2019 - February 2020, King County, Washington, USANOTE: No coxsackievirus A21 or D68 positive were detected between March 2020 May 2021 Methods We...
Abstract Background Household transmission is a major driver of SARS-CoV-2 spread. Viral genomic sequencing powerful tool for evaluation putative within-household transmission. Characteristics participants from multi-participant households with one or more positive tests Methods CASCADIA, prospective household cohort study that enrolled individuals in Oregon and Washington state, conducted active surveillance respiratory viral infection through weekly symptom surveys self-collected nasal...
Pathogen genomics can provide insights into underlying infectious disease transmission patterns1,2, but new methods are needed to handle modern large-scale pathogen genome datasets and realize this full potential3-5. In particular, genetically proximal viruses should be highly informative about events as genetic proximity indicates epidemiological linkage. Here we use pairs of identical sequences characterize fine-scale patterns using 114,298 SARS-CoV-2 genomes collected through Washington...
Abstract Background Household transmission of respiratory viruses may drive community spread. Few recent studies have examined household syncytial virus (RSV) in the United States. Methods We conducted a prospective community-based cohort study from 1 June 2022 to 31 May 2023. Participants had blood samples collected and completed nasal swabs surveys at least weekly, irrespective symptoms. tested serum for RSV antibody, by quantitative reverse transcription polymerase chain reaction...

Using a retrospective cohort study, we assessed hospitalization risk following infection with seven SARS-CoV-2 variants. Methods Our study includes individuals positive RT-PCR in Washington Disease Reporting System available viral genome data, from December 1, 2020 to January 14, 2022. analysis was restricted cases specimens collected through sentinel...
Co-circulating respiratory pathogens can interfere with or promote each other, leading to important effects on disease epidemiology. Estimating the magnitude of pathogen-pathogen interactions from clinical specimens is challenging because sampling symptomatic individuals create biased estimates.
The authors examine the determinants of information and communications technology (ICT) usage among low-income people in three developing countries: Colombia, Mexico, Peru. Using two composite indicators, they focus on cross-country differences similarities ICT across gender, age, education, income levels. authors' analysis indicates that single most important factor limiting digitalization all countries was lack education. impact itself low although positive. Their findings also suggest...
Few US studies have reexamined risk factors for SARS-CoV-2 positivity in the context of widespread vaccination and new variants or considered cocirculating endemic viruses, such as rhinovirus.To evaluate how symptoms associated with test changed over course pandemic to compare these rhinovirus positivity.This case-control study used a test-negative design multivariable logistic regression assess associations between self-reported demographic symptom variables 25-month period. The was...
Measuring the distance between countries and goal of equality opportunity in education has been focus recent contributions economic literature, which have concentrated either on intergroup gaps access to a given level studies or educational achievement. We argue that both aspects are important interrelated and, as consequence, should be measured simultaneously combined composite index education. Employing PISA data for selected set countries, rank reversals observed with respect orderings...
Este artículo estima la tasa de retorno educación población asalariada en Bogotá para 1997 y 2003 teniendo como referencia teoría del capital humano. Para estimación se corrige el sesgo selección por medio metodología Heckman (1979). A diferencia estudios anteriores, que usan Encuesta Nacional Hogares, éste utiliza información disponible Calidad Vida también es representativa Bogotá. Se encuentra los retornos experiencia potencial, así elasticidad horas-ingreso laboral ingreso reducen...
This paper analyzes the impact of Information and Communication Technologies (ICT) on academic performance students in Colombia, specifically mathematics reading. Using data from secondary school between 2017 2019, ICT access is measured through availability computers Internet. The results indicate that to ict improves scores by 0.068 standard deviations, while no significant effect observed Additionally, having a computer without Internet does not affect scores. These findings provide...
This document aims to provide evidence regarding the existence of different patterns in equality opportunities academic achievement during last fifteen years Colombia. The outcomes selected for measuring inequality are scores obtained on national test Saber 11 math as well reading. It is found that has increased this period, and trend common all metropolitan areas included analysis. Most increase comes from factors related school market. higher than 20% almost studied areas.
