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.

Assessment of microbiological aerosol concentration in selected healthcare facilities in southern Poland.

TL;DR: The identified species of staphylococci, although not typically associated with human infections, are common causal agents of nosocomial infections and infections in immunocompromised people.
Skin As Potential Source of Infectious Foot and Mouth Disease Aerosols
TL;DR: If the hypothesis that exfoliated, virus-infected animal skin cells could be an important source of infectious foot and mouth disease virus aerosols is validated, new FMDV detection, management and decontamination approaches could be developed and the relevance of skin cells to the spread of viral disease may need to be reassessed as skin cells may protect viruses against otherwise adverse environmental conditions.
Applying product design and digital construction methodologies to conceptualize modular and distributed healthcare facilities
TL;DR: In this paper, conceptual explorations in the design of modular smart health care facilities have been sought for, and a new approach towards the modular design of distantly connected built environments has been introduced that can serve to improve the quality of health care services.

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.
