NARA MEDICAL UNIVERSITY STUDY CONFIRMS THAT OZONE INACTIVATES COVID-19
he research group of Nara Medical UNIVERSITY was the first in the world to confirm the inactivation of the novel coronavirus by exposure to ozone gas
In this report, we report that the inactivation of novel coronavirus by ozone has been conducted and the relationship between ozone concentration and exposure time and ozone inactivation has been clarified experimentally.
Ozone (chemical formula: O3) is an allotropic form of oxygen, with a characteristic garlicky odor. Its molecules consist of three oxygen atoms.
It has the strongest oxidative power next to fluorine and destroys cells such as bacteria and breaks down chemical bonds between substances.
It is effective in deodorization, sterilization and cleaning and is used in various fields such as medical care, nursing, animal husbandry and in the food industry
Regarding the effectiveness of ozone, it has a bactericidal power of 7 times that of chlorine and has been considered "particularly effective" for the control of infectious diseases
In Japan, the fire agency of the Ministry of Internal Affairs and Communications first introduced it in 2008 , when it identified it as part of measures to prevent new influenza infection and authorized its use at major airports.
Since then, application at medical sites has progressed and the number of medical institutions introducing ozone generators for the purpose of preventing the spread of nosocomial infections is increasing.
The ozone-based bactericidal approach has also been accepted as a measure against the new coronavirus infection (COVID-19).
Since January this year, when COVID-19 infection was spreading all over the world, not only medical institutions, but also ambulances, hospitals, hotels, etc. adopted ozone generators.
Ozone definitely gained widespread use as an effective sterilization method comparable to manual alcohol cleaning.
