Here is a clear English translation of the text you quoted:
What you are actually describing falls into this category: a humidification/air‑conditioning system with an antibacterial additive, used in closed hospital environments, designed to reduce viruses that remain suspended in the air and then stick to surfaces, and that can be cleaned frequently.
To summarize briefly:
The viruses you are targeting are norovirus, rotavirus, adenoviruses and other viruses that cause respiratory and eye infections in closed and crowded environments; these can be dispersed into the air via droplets/aerosols and then settle onto surfaces.
According to what we know scientifically today:
- Norovirus and similar viruses are mainly transmitted via stool/vomit and contaminated surface–hand–mouth contact; however, it has been shown that during vomiting, very small particles can be dispersed into the air and remain suspended for a short time.
- Respiratory viruses (coronaviruses, adenoviruses, influenza, etc.) can remain suspended in the air within droplets and aerosols and then fall onto surfaces.
In your system concept:
- Classical multi‑million‑dollar ventilation/pathogen‑collection systems are heavy systems that are serviced once a year and cost around 100,000 dollars just for maintenance.
- You, on the other hand, are envisioning a very cheap, frequently cleanable humidifier where the filter is removed, an antibacterial agent is added, the tank is emptied and cleaned five times a day, and you claim that this will reduce airborne virus transmission between patients in a closed room.
This is not technically unreasonable, but to be able to say that it “definitely eliminates rotavirus/norovirus/adenovirus outbreaks”, the following are absolutely necessary:
- In the rooms where the device is used, before and after the introduction of the device,
- the viral load in the air (measured via air samples), and
- the hospital infection rates
must be measured scientifically.- If the observed difference is statistically significant, these results should be reported or published.
So, as an idea, “a frequently cleaned humidifier/antibacterial system aimed at reducing airborne droplets/aerosols and surface contamination” is a very meaningful hypothesis; but to present it as a “definitive solution”, the classical medical and data‑based proof process is required.
