Something to consider. The @CDCgov and @WHO's contact trace methods are based on direct contact.
They wouldn't know how to use the Gesundheit 2 to save @DrTedros's reputation. Or how to do full traces, including everyone in the room. Or in the next room.
To use smoke.
So, all of those epi studies?
About as useful as @RWalensky 's magical 5 day isolation policy, when trying to rule out airborne transmission.
How about this? You nay-sayers, explain the origin of the 6 foot distance rule. The 15 minute transmission rule used today.
I can explain where they come from, can you?
Sorry if I am being aggressive.
We have sat around for far too long. I am calling it like I see it, and it's all self-reinforcing bullshit.
I am talking directly to you, John Conly and others of his ilk.
Get out of the damn way.
Let me show you what I mean by self-reinforcing.
In this fascinating treatment of a lost case of Marburg, the authors explore how the wife got infected.
"...due to the desirability of an off-
the-face design, and not for protection from aerosols, respirators may be used instead of medical masks"who.int/publications/i…
If you can stay 3 feet away while screening? No medical mask needed.
PCDH1 (protocadherin-1) is primarily expressed in the airway epithelium of the respiratory system, especially in the bronchial and nasal epithelial cells, and in pulmonary endothelial cells.
@mvankerkhove - a follow-up question on today's press conference.
In this bit, you were thanked for being very clear.
But, you said that the medical personnel taking care of those sick would be wearing PPE.
N95s are not PPE. They are Respiratory Protective Equipment. /1
Surgical masks are PPE.
So, is the WHO advising them to wear surgical masks or N95s/FFP2/KF94/KN95 (respirators)?
Second followup, @mvankerkhove, you referred to "really close contacts"
Close contacts are defined by the WHO as within 3 feet.
Cases 1 & 2 were close contacts.
How did the other cases get it? I realize you cannot possibly have an answer...but you are labeling this as "really close contact" for those cases - as well.
I've become a bit of a Dental Nerd after just getting savaged by avoiding the dentist due to COVID.
But, now, I have a Dental Nasal PAPR, know all about Stephan's Curve, use a waterpik, Oral-B iO Series 10, chew 8 pieces of xylitol gum - and the dentist just said that.....
He has never seen anyone reverse course so perfectly before.
"Immaculate."
And bonus...I ran into a fellow masker in his lobby!!
She had never heard of Readimask, so I was super happy to share the Good Word with her.
