Please note, "other microbial bioaerosols" in the title.
It is likely in an environment like a hospital not ALL spread is airborne, nor is all of it respiratory pathogens, of course. But I rather suspect a lot more things we typically have thought of as "contact" are in fact airborne, whether thrown up or actually respired.
This is from an online textbook, under heading "nosocomial infections", and you can see they relegate multi-drug resistant bacteria, including MRSA, to contact only.
Just remember the ladder of denial and elite panic myth means if you are hearing a 2 it's a 4. If a 4 it's a 6. If a 6 pack your bags. You'll never hear 8 and up the TV will just play static
Has anyone worked up the ladder of denial for bird flu?
- We have not found bird flu.
- We have found bird flu in one bird. There is no evidence of bird to bird transmission.
- We have found bird flu in many birds and there is bird to bird transmission but it has not moved to other mammals.
- We have found bird flu in a cow. However, we have not found evidence of cow to cow transmission.
- We have now found bird flu in many cows.
- We have now found evidence of cow to cow transmission but we do not know how this is happening.
- We found some bird flu in the milk. You should not worry because this might not be live virus. However, for some reason, we now think milk is the vector of transmission.
It means negative pressure rooms and N95s, which is why they desperately do not want COVID to be called "Airborne".
This is why, during SARS, when a roomful of Canadian doctors and nurses got sick even though they were using "Droplet precautions" (I'll capitalize) - that is, medical masks - they invented AGMP, so they could explain how a droplet virus infected people using Droplet Precautions.
