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.

Hospital ventilation simulation for the study of potential exposure to contaminants
TL;DR: The present study highlights the fact that the CFD-FEM application is useful for understanding the efficiency, adequacy and reliability of the ventilation system, but also provides important suggestions for controlling air quality, patients’ comfort and energy consumption in a hospital.

Assessing the social and environmental determinants of pertussis epidemics in Queensland, Australia: a Bayesian spatio-temporal analysis.

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.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

TL;DR: Overall, foodborne diseases appear to cause more illnesses but fewer deaths than previously estimated.
