TLDR
In this article, a new expiratory droplet investigation system (EDIS) was used to conduct the most comprehensive program of study to date, of the dilution corrected droplet size distributions produced during different respiratory activities.About:

Journal ArticleDOI
Airborne transmission of SARS-CoV-2: The world should face the reality.
Lidia Morawska,Junji Cao +1 more
TL;DR: It is extremely important, that the national authorities acknowledge the reality that the virus spreads through air, and recommend that adequate control measures be implemented to prevent further spread of the SARS-CoV-2 virus, in particularly removal of the virus-laden droplets from indoor air by ventilation.
Journal ArticleDOI
The airborne lifetime of small speech droplets and their potential importance in SARS-CoV-2 transmission.
TL;DR: Observations confirm that there is a substantial probability that normal speaking causes airborne virus transmission in confined environments.

Aerosol emission and superemission during human speech increase with voice loudness
Sima Asadi,Anthony S. Wexler,Christopher D. Cappa,Santiago Barreda,Nicole M. Bouvier,William D. Ristenpart +5 more
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.
Journal ArticleDOI
Violent expiratory events: on coughing and sneezing
TL;DR: In this paper, the authors present the results of a combined experimental and theoretical investigation of the fluid dynamics of such violent expiratory events, which reveals that such flows are multiphase turbulent buoyant clouds with suspended droplets of various sizes.

Toward Understanding the Risk of Secondary Airborne Infection: Emission of Respirable Pathogens
TL;DR: Patients termed “superspreaders” or “dangerous disseminators” are those infrequently encountered persons with high values of cough and/or sneeze frequency, elevated pathogen concentration in respiratory fluid, and/ or increased respirable aerosol volume per expiratory event such that their pathogen emission rate is much higher than average.
