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-associated infections and the safety of alcohol hand gels in children
TL;DR: Alcohol-based hand gels were found to be safe in children’s use, as no absorption was detected despite several contacts between hands and mucous membranes, and electronic follow-up is useful in evaluating their magnitude.

Health Care Associated Infections: Sources and Routes of Transmission
TL;DR: Health care associated infections are infections that patients acquire, while they are in contact with the healthcare system, which also include occupational infectious diseases acquired by health care workers.

Multiscale modeling of in-room temperature distribution with human occupancy data: a practical case study
TL;DR: The developed method for modelling of in-room temperature distribution incorporated with data collected by human sensors is applied to a practical office space in commercial building in Japan and its effectiveness is demonstrated by comparing numerical simulations of the equation with measured data on temperature.

Evidence of Long-Distance Aerial Convection of Variola Virus and Implications for Disease Control
TL;DR: Analysis of data obtained from a systematic review following the PRISMA criteria, on the long-distance transmission of smallpox finds evidence of aerial convection appears unique to the variola virus and is not considered in current hospital infection control protocols.
Experimental measurements of human cough airflows from healthy subjects and those infected with respiratory viruses
TL;DR: This book aims to provide a history of web exceptionalism from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year in which descriptions of “Web 2.0” began to circulate.

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.
