Recommendations are made to improve the control of aerosol-transmitted infections in hospitals as well as in the design and construction of future isolation facilities.
Abstract
Summary The epidemics of severe acute respiratory syndrome (SARS) in 2003 highlighted both short- and long-range transmission routes, i.e. between infected patients and healthcare workers, and between distant locations. With other infections such as tuberculosis, measles and chickenpox, the concept of aerosol transmission is so well accepted that isolation of such patients is the norm. With current concerns about a possible approaching influenza pandemic, the control of transmission via infectious air has become more important. Therefore, the aim of this review is to describe the factors involved in: (1) the generation of an infectious aerosol, (2) the transmission of infectious droplets or droplet nuclei from this aerosol, and (3) the potential for inhalation of such droplets or droplet nuclei by a susceptible host. On this basis, recommendations are made to improve the control of aerosol-transmitted infections in hospitals as well as in the design and construction of future isolation facilities.

A Review of the Research Literature on Evidence-Based Healthcare Design

TL;DR: This review found a growing body of rigorous studies to guide healthcare design, especially with respect to reducing the frequency of hospital-acquired infections and the state of knowledge of evidence-based healthcare design has grown rapidly in recent years.

Transmission of COVID-19 virus by droplets and aerosols: A critical review on the unresolved dichotomy.

TL;DR: It is demonstrated that the nosocomial transmission by airborne SARS-CoV-2 viral-laden aerosols in healthcare facilities may be plausible and clearly defined, science-based administrative, clinical, and physical measures are of paramount importance to eradicate the COVID-19 pandemic from the world.
Journal ArticleDOI

Violent expiratory events: on coughing and sneezing

TL;DR: In this paper, the authors present the results of a combined experimental and theoretical investigation of the fluid dynamics of such violent expiratory events, which reveals that such flows are multiphase turbulent buoyant clouds with suspended droplets of various sizes.

Recognition of aerosol transmission of infectious agents: a commentary

TL;DR: This review considers the commonly used term of ‘aerosol transmission’ in the context of some infectious agents that are well-recognized to be transmissible via the airborne route, and discusses other agents, like influenza virus, where the potential for airborne transmission is much more dependent on various host, viral and environmental factors, and where its potential for aerosol transmission may be underestimated.

The fluid mechanics of natural ventilation

TL;DR: In this paper, two forms of ventilation are discussed: mixing ventilation and displacement ventilation, where the interior is at an approximately uniform temperature and there is strong internal stratification, respectively, and the effects of wind on them are examined.

Studies on the Epidemiology of Colitis Due to Clostridium difficile in Hamsters

TL;DR: It was not possible to determine which of the sources of the organism was most important in its spread, but cross-infection with C. difficile may be important in the pathogenesis of antibiotic-associated enterocolitis in hamster colonies.

Bioaerosol Production on a Respiratory Ward

TL;DR: A short aerobiological survey on a respiratory ward at St James’s University Hospital in Leeds found a correlation between activity and aerosol production.

Exposure to blood-containing aerosols in the operating room: a preliminary study.

TL;DR: Data show that the mucous membrane lining of the upper respiratory tract and alveolar macrophages in the gas-exchange region are likely to be exposed to aerosolized blood in the operating room.

Fluid displacement by high Reynolds number bubble motion in a thin gap

TL;DR: In this article, the fluid displacement associated with the injection and subsequent translation of high Reynolds number bubbles in a thin gap is examined experimentally, and compared with a theoretical model based on a two-dimensional inviscid flow calculation.
