“COMMENTARY: Health workers need optimal respiratory protection for Ebola”
“Editor’s Note: Today’s commentary was submitted to CIDRAP by the authors, who are national experts on respiratory protection and infectious disease transmission. In May they published a similar commentary on MERS-CoV. Dr Brosseau is a Professor and Dr Jones an Assistant Professor in the School of Public Health, Division of Environmental and Occupational Health Sciences, at the University of Illinois at Chicago.”

Oh...Fudge.
That CIDRAP article does cut to the chase about the nature of Faluci’s lying before Congress —
“Adequate protection is essential
To summarize, for the following reasons we believe that Ebola could be an opportunistic aerosol-transmissible disease requiring adequate respiratory protection:
•Patients and procedures generate aerosols, and Ebola virus remains viable in aerosols for up to 90 minutes.
•All sizes of aerosol particles are easily inhaled both near to and far from the patient.
•Crowding, limited air exchange, and close interactions with patients all contribute to the probability that healthcare workers will be exposed to high concentrations of very toxic infectious aerosols.
•Ebola targets immune response cells found in all epithelial tissues, including in the respiratory and gastrointestinal system.
•Experimental data support aerosols as a mode of disease transmission in non-human primates.
Risk level and working conditions suggest that a PAPR will be more protective, cost-effective, and comfortable than an N95 filtering facepiece respirator.

The hair on my arm was standing on end.
Isn't this what a lot of people, even on this very forum have been talking about?? Warning about? This makes so much sense. The way this thing is spreading out of control, even to people who claim no direct contact to infected persons, not to mention all the infections of the HCWs, fully covered in PPE.
This from the article:
The potential for transmission via inhalation of aerosols, therefore, cannot be ruled out by the observed risk factors or our knowledge of the infection process. Many body fluids, such as vomit, diarrhea, blood, and saliva, are capable of creating inhalable aerosol particles in the immediate vicinity of an infected person. Cough was identified among some cases in a 1995 outbreak in Kikwit, Democratic Republic of the Congo,11 and coughs are known to emit viruses in respirable particles.17 The act of vomiting produces an aerosol and has been implicated in airborne transmission of gastrointestinal viruses.18,19 Regarding diarrhea, even when contained by toilets, toilet flushing emits a pathogen-laden aerosol that disperses in the air.20-22
How many public restrooms have lids on the toilets? Most of the commercial ones have such powerful flushes, they spray everywhere and leave water drops on the seat. In the case of an Ebola-infected person using a public restroom? Welcome to- yet another- nightmare.
Lord have mercy!
