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.

Modelling infection risk due to environmental contamination in hospital single and multi-bed ward accommodation
TL;DR: Results demonstrate that enforcing hand hygiene due to the knowledge of an infectious patient makes single rooms significantly less risk prone, and indicate that hand hygiene carried out by nurses may need to be rethought.

Transport and Deposition of Evaporating Droplets in a Ventilated Environment
TL;DR: In this paper, the trajectories of droplets were evaluated using the Lagrangian approach by solving the equation of droplet motion that included the inertial, viscous drag, Brownian, Saffman lift, and gravity forces.

Evaluation of Indoor Air Quality in Different Hospital Wards by Bioaerosol Sampling and Particle Counting in 2016
TL;DR: Investigation in various wards of a hospital in Qazvin province, Iran found bioaerosol concentration was higher in the hospital than in outdoor, which might be related to the presence of patients, their activities, as well as unsuitable ventilation and disinfection.

Inactivation of porcine reproductive and respiratory syndrome (PRRS) virus
TL;DR: The results obtained allowed us to assess the importance of knowing the carrier and removal status of canine coronavirus, as a source of infection for other animals, not necessarily belonging to the same breeds.

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.
