Influenza virus in human exhaled breath: an observational study.

TL;DR: It is shown that the rate of particle emission during normal human speech is positively correlated with the loudness (amplitude) of vocalization, and the phenomenon of speech superemission cannot be fully explained either by the phonic structures or the amplitude of the speech.

TL;DR: This review considers the commonly used term of ‘aerosol transmission’ in the context of some infectious agents that are well-recognized to be transmissible via the airborne route, and discusses other agents, like influenza virus, where the potential for airborne transmission is much more dependent on various host, viral and environmental factors, and where its potential for aerosol transmission may be underestimated.

TL;DR: The abundance of viral copies in fine particle aerosols and evidence for their infectiousness suggests an important role in seasonal influenza transmission.

TL;DR: In this article, the authors integrated the results of two different investigative techniques spanning 3 decades of particle size from 700nm to 1mm, presenting a single composite size distribution, and identifying the most prominent modes in that distribution.

TL;DR: A measles epidemic in a modern suburban elementary school in upstate New York in spring, 1974, is analyzed in terms of a model which provides a basis for apportioning the chance of infection from classmates sharing the same home room, from airborne organisms recirculated by the ventilating system, and from exposure in school buses.

TL;DR: Extensive evidence indicates that aerosol transmission of influenza occurs and should be taken into account for pandemic planning.

TL;DR: It is concluded that transmission occurs at close range rather than over long distances, suggesting that airborne transmission, as traditionally defined, is unlikely to be of significance in most clinical settings.

TL;DR: C coughing produced the largest droplet concentrations and nose breathing the least, although considerable intersubject variability was observed, and the existence of larger sized droplets in the exhaled breath was confirmed.
