⚠️@MIT's Dr. Lydia Bourouiba warns: “pathogen-bearing droplets of ALL sizes can travel 23-27 feet.”

She also warns: “droplets that settle along the trajectory can contaminate surfaces”—and “residues or droplet nuclei” may “stay suspended in the air for HOURS.”😳

#COVID19 #masks

Bourouiba fears @WHO's current guidelines are “overly simplified” and “may limit the effectiveness of the proposed interventions” against #coronavirus.

“There’s an urgency in revising the guidelines currently being given by the [WHO] and the [@CDCgov].

"The rapid international spread of #COVID19 suggests (current assumptions) may not accurately reflect what actually occurs w/respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread" of #coronavirus.

Dr. Bourouiba, an expert in the dynamics of coughs and sneezes: "A 2020 report from #China demonstrated that #SARSCoV2 virus particles could be found **in the ventilation systems** in hospital rooms of patients with #COVID19."💥

Dr. Bourouiba's research (published in @JAMA_current) strongly suggests:

▶️Healthcare workers may be at an even HIGHER risk for exposure to #coronavirus, than previously thought
▶️6-foot #PhysicalDistancing may not be sufficient
▶️#Masks may be necessary

These data strongly suggest that EVERYONE should wear #masks outside home, but healthcare workers & people at high-risk for serious #COVID19 need them MOST.

Given the global shortage of #Masks/other #PPE, Trump must invoke the #DefenseProductionAct NOW‼️
