To those scientific minds who enter the symptoms of Covid-19: if you find a desire and ability to experiment, you may find the courage to try a light ozone generator in a mostly closed room.
Healthcare systems of many countries are cornered by these assumptions: 1) light ozone generators cannot do a thing because they produce tiny concentrations of gas 2) the ozone is toxic.
While both of those statements are somewhat true, here is the thing.
The dangerous side of Covid-19 is its ability to target lungs in a fraction of patients. While this is a dangerous situation, it also makes it potentially susceptible to inhale treatments.
Now back to ozone. It is basically a recombined atoms of oxygen, but instead of ubiquitous O2, ozone is O3. As you might expect, it has higher oxidizing ability. Human can safely breathe ozone as long as its concentration goes below 0.2 mg/m3.
Ozone is not only a breathable gas. It also has an ability to disinfect. For example, it deactivates the viruses by over-oxidizing its surfaces.
Regarding the concentrations. It was shown that to kill 90% of SARS-CoV you would need an exposure of 20-112 mg / m3 during one minute. Which sounds like a lot but bare with me.
A disinfection with ozone has an accumulative effect, pretty much like with UV or radiation. For instance, a home ozonator (ozone generator) typically produces a concentration of 0.02 mg/m3. It would not kill the virus in a minute. But it will start to do so in 17 hours of exposure (20 mg/m3 / 0.02 mg/m3 / 60 min/hour = 16.6 hours).
Ozone can be generated in several ways. One of those is by exposing the air to UV-C. This is a preferable method for virus situation, because not only the desired gas is generated, but also because UV-C light has an ability to disinfect the air and surfaces by itself. A win-win.
Please note that UV-C may be critically dangerous to skin and eyes. To overcome that problem, UV-C lamp should be placed in a black or UV insulating box, where only a small laminar flow of air produced by the fan is exposed to UV-C. The suggested power of such a lamp would be something Now to effects: tiny fractions of ozone would cause a small sedative effect. If the breath is difficult then you may find a tiny amount of O3 more supportive comparing to conventional air mixture which is already a big bonus.
In 17 hours or so of exposure, you are going to feel better, as the consumed concentration is already promises to deactivate a substantial amount of exposed virus material (like 90%).
The good things do not end here, as deactivation rate is exponential and in 34 hours you are going to get 99% of exposed virus material deactivated.
Now to the not so good things: ozone is slightly toxic and you would not be able to use it for too long. 3 days of presumably safe concentration is already close to a stretch. It not only damages viruses and bacteria, it also over-oxidizes human cells which leads to their eventual damage. It is usually felt like a soar throat.
The important points to consider when trying to implement the experiment like this: 1) safe O3 concentration 2) no direct human exposure to UV-C 3) room should be on a smaller side, as it is easier to control (8-20 m2 is a sweet spot) 4) the room should be mostly closed, do not ventilate the room more often than once or twice per 24 hours for short periods of time like 5-10 minutes; note, that you still need an air to breathe, so a "mostly closed room" would not mean a "scientifically firmly closed room".
Did I try this extreme idea myself before publicly suggesting it? Yes, I did. Though for more conventional viruses like seasonal flu. I was never officially diagnosed with Covid-19, but I'm pretty confident I went through it in the middle of February when nobody had a test yet.
The idea may sound controversial to the most of population nowadays. But it surely is effective on viruses as I've experimented with it for 7 years.
I am putting this publicly to spark the minds of researches, including professionals. This is a low hanging fruit so I'm surprised to admit that nobody had tried it before in scientifically controlled environment, with control groups and stuff.
DISCLAIMER: If you do this you do it on your own risk. The large dozes of ozone and UV can be extremely dangerous and may lead to fatal consequences or even death. This is not a scientifically proven treatment of Covid-19.
