TLDR
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
Roger S. Ulrich,Craig Zimring,Xuemei Zhu,Jennifer R. DuBose,Hyun-Bo Seo,Young-Seon Choi,Xiaobo Quan,Anjali Joseph +7 more
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.

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.

TL;DR: In this paper, a Bayesian spatio-temporal model was used to quantify the relationship between monthly pertussis incidence and socio-environmental factors, including monthly mean minimum temperature (MIT), monthly mean vapour pressure (VAP), Queensland school calendar pattern (SCP), and socioeconomic index for area (SEIFA).

Transmission by super-spreading event of pandemic A/H1N1 2009 influenza during road and train travel
Vincent Pestre,Bruno Morel,Nathalie Encrenaz,Amandine Brunon,Frédéric Lucht,Bruno Pozzetto,Philippe Berthelot +6 more
TL;DR: Results suggest that super-spreading of flu can occur in a confined space without sufficient air renewal, and suggest transportation as the circumstance of transmission.

Hemagglutinin gene based biosensor for early detection of swine flu (H1N1) infection in human
TL;DR: Im impedimetric biosensor is not only highly specific for H1N1 virus but also can detect as low as 0.004 ng (limit of detection) ss-cDNA in 6 µL only in 30 min.

Molecular epidemiology of invasive stomatitis due to Aspergillus flavus in patients with acute leukemia

TL;DR: The molecular analysis of the epidemiology of invasive stomatitis due to Aspergillus flavus in patients with acute leukemia revealed that three isolates of A. flavus obtained in 1992 from three patients were of the same type, whereas each of the isolates from the other three patients had a distinct unique band.
