Hydration reduces respiratory drop generation, may reduce #COVID19 risks on seacoasts — new data with colleagues at @NIH, @HarvardChanSPH, and @MassGeneralNews. https://t.co/MB9dEZcKrY

.@CDCgov has updated their brief informing the public of what we’ve been advocating since our first publication last summer… citing our research. The government is officially recognizing that SARS-CoV-2 is transmitted by exposure to infectious respiratory fluids.

Exhaled respiratory droplets vary strongly between individuals. Our recent work suggests factors include lung infection, age, and BMI.
Here is a recent article I wrote in Molecular Frontiers that covers this research:

Excited to be doing a study in Grand Rapids on the campus of Grand Rapids Community College next week. Here Dr. Pink, president of GRCC, and I discuss the need for new hygiene innovations in the education and workplace.

Thank you Shawna Williams for the call-out to our #aerosol research - @TheScientistLLC. "Scientists’ Advice for Ways to Ward off the #Coronavirus" @coloradan @helloFEND @CloudSensory #Covid19

2/2 This paper shows that ventilation efficiency depends on partition location, where supply air and exhaust vents are located, and where is the source of contamination https://t.co/0hZPwzqgX9

[Shelly Miller, PhD @ShellyMBoulder]

1/2 We do not recommend acrylic room dividers for reducing risk of airborne transmission. At best it does NOTHING, at worse it changes the airflow patterns in the room and can cause pooling of air, hotspots, and reduced ventilation effectiveness.

The evolution of an idea: inhaling salts, exhaling clean air, and the creation of a particle suppression effect. #aerosols #bioaerosols @helloFEND @CloudSensory https://t.co/P1olGyq1wo

CDC acknowledges that airborne transmission plays a role in coronavirus spread. #aerosols #bioaerosols https://t.co/AwbYecBhAG

[Dr. David Edwards @davidedwardsphd]

Our research in human & nonhuman subjects, with & without COVID19, found that the number of #aerosols exhaled increased dramatically w/ COVID-19 infection, aging & high BMI: 1-3 orders of magnitude higher compared to healthy subjects. #COVID19 #bioaerosols https://t.co/9ONz4k5bdV

[Dr. David Edwards @davidedwardsphd]

The number of #aerosols people exhale varies greatly-some as low as 5 particles per milliliters of air and others as high as 10,000/ml. These numbers can fluctuate throughout the day. Age & those w/high BMI expel higher levels of aerosols. #bioaerosols #COVID-19 #Flu #ventilation

[Dr. David Edwards @davidedwardsphd]

Very informative segment about #bioaerosols. Better understanding about the risks of airborne transmission should encourage preventative action, especially the implementation of effective ventilation protocols for indoor gatherings.

Do aerosols play a role in COVID19 transmission?
Huge thanks to #aerosol scientists ⁦@kprather88⁩ and ⁦@linseymarr⁩ for explaining how #SARSCoV2 virus can spread through the air, & how knowing that can help us stop the spread of #COVID19.

@SMitragotri Thank you Samir.

[Dr. David Edwards @davidedwardsphd]

Observed a reduction of up to 99% in those exhaling most particles and on average 75% for all subjects. Published today in @molfrontiers. #COVID19 #airborneinfectiousdisease

Pleased to share the results of our studies showing a significant reduction of exhaled #bioaerosols, incl. sub-micron, when using a calcium-enriched nasal salt solution. Studied 76 essential workers and family members & compared to the wearing of surgical masks. - 1
