The risk of progression from exposure to the tuberculosis bacilli development active disease is a two-stage process governed by both exogenous and endogenous factors. Exogenous factors play key role in accentuating infection among which bacillary load sputum proximity an individual infectious TB case are Similarly lead disease. Along with well-established (such as human immunodeficiency virus (HIV), malnutrition, young age), emerging variables such diabetes, indoor air pollution, alcohol,...
Introduction Transmission of COVID-19 within families and close contacts accounts for the majority epidemic growth. Community mask wearing, hand washing social distancing are thought to be effective but there is little evidence inform or support community members on risk reduction families. Methods A retrospective cohort study 335 people in 124 with at least one laboratory confirmed case was conducted from 28 February 27 March 2020, Beijing, China. The outcome interest secondary transmission...
Editor's Note The authors of this article, published in 2015, have written a response to their work light the COVID-19 pandemic. We urge our readers consider when reading article. https://bmjopen.bmj.com/content/5/4/e006577.responses#covid-19-shortages-of-masks-and-the-use-of-cloth-masks-as-a-last-resort Objective aim study was compare efficacy cloth masks medical hospital healthcare workers (HCWs). null hypothesis is that there no difference between and masks. Setting 14...
Many countries are stockpiling face masks for use as a nonpharmaceutical intervention to control virus transmission during an influenza pandemic. We conducted prospective cluster-randomized trial comparing surgical masks, non-fit-tested P2 and no in prevention of influenza-like illness (ILI) households. Mask adherence was self-reported. During the 2006 2007 winter seasons, 286 exposed adults from 143 households who had been child with clinical respiratory were recruited. found that mask...
Abstract Many countries are stockpiling face masks for use as a nonpharmaceutical intervention to control virus transmission during an influenza pandemic. We conducted prospective cluster-randomized trial comparing surgical masks, non–fit-tested P2 and no in prevention of influenza-like illness (ILI) households. Mask adherence was self-reported. During the 2006 2007 winter seasons, 286 exposed adults from 143 households who had been child with clinical respiratory were recruited. found that...
We compared the efficacy of medical masks, N95 respirators (fit tested and non fit tested), in health care workers (HCWs).A cluster randomized clinical trial (RCT) 1441 HCWs 15 Beijing hospitals was performed during 2008/2009 winter. Participants wore masks or entire work shift for 4 weeks. Outcomes included respiratory illness (CRI), influenza-like (ILI), laboratory-confirmed virus infection influenza. A convenience no-mask/respirator group 481 from nine compared.The rates CRI (3·9% versus...
Background: eHealth is an application of information and communication technologies across the whole range functions that affect health. The benefits (eg, improvement health care operational efficiency quality patient care) have previously been documented in literature. Health providers medical doctors) are key driving force pushing initiatives. Without their acceptance actual use, those would be unlikely to reaped. Objective: To identify synthesize influential factors providers' various...
There is widespread hesitancy towards COVID-19 vaccines in the United States, Kingdom, and Australia.To identify predictors of willingness to vaccinate against five cities with varying incidence US, UK, Australia.Online, cross-sectional survey adults from Dynata's research panel July-September 2020.Adults aged 18 over Sydney, Melbourne, London, New York City, or Phoenix.Willingness receive a vaccine; reason for vaccine intention.To intention vaccine, we used Poisson regression robust error...
ObjectivesTo determine patterns of mask wearing and other infection prevention behaviours, over two time periods the COVID-19 pandemic, in cities where was not a cultural norm.MethodsA cross-sectional survey masks preventive behaviours adults aged ≥18 years conducted five cities: Sydney Melbourne, Australia; London, UK; Phoenix New York, USA. Data were analysed according to epidemiology COVID-19, mandates range predictors wearing.ResultsThe most common measures used avoiding public areas...
Rationale Medical masks are commonly used by sick individuals with influenza-like illness (ILI) to prevent spread of infections others, but clinical efficacy data absent. Objective Determine whether medical mask use ILI protects well contacts from related respiratory infections. Setting 6 major hospitals in 2 districts Beijing, China. Design Cluster randomised controlled trial. Participants 245 index cases ILI. Intervention Index were randomly allocated (n=123) and control arms (n=122)....
Medical masks are commonly used in health care settings to protect healthcare workers (HCWs) from respiratory and other infections. Airborne pathogens may settle on the surface of layers, resulting contamination. The main aim this study was presence viruses medical masks.Two pilot studies laboratory clinical were carried out determine areas likely contain maximum viral particles. A using a mannequin fluorescent spray showed particles concentrated upper right, middle left sections masks....
Abstract Cloth masks have been used in healthcare and community settings to protect the wearer from respiratory infections. The use of cloth during coronavirus disease (COVID-19) pandemic is under debate. filtration effectiveness generally lower than that medical respirators; however, may provide some protection if well designed correctly. Multilayer masks, fit around face made water-resistant fabric with a high number threads finer weave, reasonable protection. Until mask design proven be...
Several vaccines for SARS-CoV-2 are expected to be available in Australia 2021. Initial supply is limited and will require a judicious vaccination strategy until unrestricted. If have efficacy as post-exposure prophylaxis (PEP) contacts, this provides more policy options. We used deterministic mathematical model of epidemic response with (age-targeted or ring vaccination) mass the State New South Wales (NSW) Australia. For targeted vaccination, effectiveness vaccinating health workers, young...
Evidence-based medicine (EBM’s) traditional methods, especially randomised controlled trials (RCTs) and meta-analyses, along with risk-of-bias tools checklists, have contributed significantly to the science of COVID-19. But these methods were designed primarily answer simple, focused questions in a stable context where yesterday’s research can be mapped more or less unproblematically onto today’s clinical policy questions. They significant limitations when extended complex about novel...
