[DIYbio] Re: Covid-19 superspreaders

The problem is the anatomy of the upper respiratory tract. The nose is kind of a "drain" at the low point. The interior is very complex with a large surface area.  Lets assume you are driving saltwater, saline, or whatever "up" into your respiratory tract. Now you may have possibly transported a virus that is capable of attacking your cells way up in these labyrinthine folds which are very close to the brain. There is an old medical shorthand for this area, its called "the triangle of death", from the corners of the mouth to the bridge of the nose. Deaths have occurred from users of saline irrigation, then transporting waterborne amoebas up there, that otherwise exist in municipal water systems, and don't cause problems because they aren't transported into these areas. This area is NOT designed to be tampered with. If the human body had an area that should be stamped with "no user serviceable parts" it is this area. You cannot optimize this system. It is a diverse ecosystem of immune defenses, from populations of phages, innumerable antibodies, beneficial polysaccharides, etc., etc., all working together.  Instead of external treatment, there are various ways to increase the natural function of this system: things like spicy food, capsacin, pepper, sad movies featuring orphaned puppies, etc. Anything that will induce a tears and mucus production.

Hello Together,

I have a question to you! Maybe someone knows something about it.

In the last months i searched in my freetime for data or scientific studies if i can find something about the maybe slower spread of Covid-19 or lower infection rate in the group of people, who spend a lot of time in or at salt water. For example: diver, surfer, fisher etc., or Covid-19 data about places where they live.

Because i wonder, if it could be possible to reduce the high Sars-CoV-2 viral load in the upper airways with salt-water. And use it in a nose spray, for example.
Additionaly it could relieve sneeze* and the nasal congestion.  
(maybe a normal isotonized salt-water-spray will do, possibly a mixture with too strong salt content is not suitable for the long term use)

Perhaps, if the most of us do this as a additionally preventive measure, the high spread of Covid-19 could be reduced a little? Especially in the group of superspreaders i can imagine an effect.

* Recently I found an interesting study in this regard: "A study of fluid dynamics and human factors driving droplet dispersion from a human sneeze": https://aip.scitation.org/doi/10.1063/5.0032006 (Physics of Fluids,12. November 2020)

As far as I know, the measure can also strengthen the mucous membranes, make them more resistant and moisty, especially when people are often in closed rooms.

What do you think, could it do anything? Or do you know who I could ask about it?

Thank you very much.

Best Wishes,
Jochen
