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.

Viral kinetics and exhaled droplet size affect indoor transmission dynamics of influenza infection
TL;DR: A predictive model that can integrate the influenza viral kinetics, indoor aerosol transmission potential, and population dynamic model [susceptible - exposed - infected - recovery (SEIR) model] in a proposed susceptible population is provided.

Delivery of RNAi Therapeutics to the Airways—From Bench to Bedside
TL;DR: The different barriers to pulmonary drug delivery are introduced, the potential of RNAi molecules as new class of therapeutics, and the latest preclinical and clinical studies of using RNAi therapeutics in different respiratory conditions are discussed in details.

Novel light-activated antimicrobial coatings are effective against surface-deposited Staphylococcus aureus.
TL;DR: It is shown that a coating containing toluidine blue and rose bengal can achieve significant kills of S. aureus when illuminated by a domestic light source, and could provide a simple, low-cost means of reducing the microbial load in hospitals and other facilities.

Potential airborne transmission between two isolation cubicles through a shared anteroom.
TL;DR: Analysis of full-scale experiments and CFD simulations suggest a potential inter-cubicle infection risk if the shared anteroom is used for multiple isolation cubicles and decreases the duration of door opening, raising air change rate or using a curtain at the doorway are recommended to reduce inter-Cubicle exposure hazards.

TL;DR: In this paper, a statistical treatment was conducted over a database of indoor air parameters and the primary schools where these parameters were sampled (urban area of Lisbon, Portugal), and the aim of this study was to assess the associations between indoor air indicators with the schools' building characteristics, through the use of statistical methods.

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.
