No, I haven't done that in many years actually. I did get in some fiction reading for the first time in a while. That was nice.

You doing okay? It's been a rough year+ there.

Everyone mr🐪

It's also factual that direct contact with infectious materials is the *greater* risk.
Another fact is that unless the virus changes, NiV will not spread like a true respiratory virus spreads.

Yep, droplets are part of the definition of infectious respiratory particles.
And there is definitely risk from proximity.
These are both facts.
Protect your airways if you are in close contact with a sick person. 1/2

That all exists and remains documented. But not every pathogen transmits *mainly* by aerosol.
Nipah seems to require a much larger dose than e.g. SARS-CoV-2 or MeV favouring proximity for transmission prps by direct deposition. That dose may be achieved more common via direct & indirect contact

"Additionally, the new term of ‘direct deposition’ is akin to the existing ‘droplet transmission’ mode, but without any specific particle size designation"
So I'll reword my earlier post...

I'd argue this has now been well defined...
Terms like...
🌬️ Infectious Respiratory Particles
🌬️ Direct deposition
...are now defined

That all exists and remains documented. Bit not every pathogen transmits mainly that way.
Nipah seems to require a much larger dose than e.g. SARS-CoV-2 or MeV to transmit via suspected droplets (or aerosols). That dose may be achieved by long time periods spent physically close, near coughs etc.

Thabks I'll add these to my not-small eLibrary. 🙂

Distance, gloves and handwahsing are very important with this virus. Transmission through the air is not seen to be very frequent. But prolonged (dose) and close contact (fluid exchange) are.
I'm not excluding the need for masks by saying this, just offering a ranking of transmission risks.
