New corona low-concentration ozone gas suppresses infectivity Fujita Medical University August 26, 22:14
Fujita Medical University in Aichi Prefecture announced the result that it was effective in suppressing the infectivity of the new coronavirus in an experiment using ozone gas that had no effect on health.
According to Fujita Medical University, it has been reported that high concentration of "ozone gas" has the effect of suppressing the infectivity of the new coronavirus, but its toxicity to the human body is becoming an issue. It was
Professor Takayuki Murata of Fujita Medical University put stainless steel with a new type of coronavirus in a sealed container, and it is said that health will not be affected by Japanese work environment standards in the container "0.1 ppm" We conducted an experiment to see the effect by generating low-concentration ozone gas.
As a result, under the condition of 80% humidity, after 10 hours, the amount of infectious virus was reduced to 4.6% of that without treatment.
Even when the experiment was conducted at a lower concentration of "0.05 ppm", the amount of infectious virus was reduced to 5.7% after 20 hours, which means that ozone gas at a low concentration that is not harmful to the human body, It has become clear that it has the effect of suppressing the infectivity of the new coronavirus.
On the other hand, at 55% humidity, the amount of virus did not decrease as much as at 80%.
Based on the results of this experiment, Fujita Medical University will install ozone generators in waiting rooms and hospital rooms of hospitals from next month.
