A research group of the Faculty of Medicine of the University of Nara in Japan, directed by Professor Toshikazu Yano of the Department of Infectious and Pathogenic Diseases and by Prof. Kei Kasahara of the Center for Infectious Diseases, conducted an experiment to test the potential of ozone to sanitize environments and deactivate the virus.

The experiment, repeated several times, has completely succeeded in demonstrating that ozone is able to deactivate and destroy the coronavirus. To communicate this good news, the Faculty of Medicine of the University of Nara released, on 14 May, a press release published by the editorial staff ,Orbisphera,  in which he explained some details of the trial.

In the clinics, as is the case in the most diverse meeting places of people (clubs, bars, restaurants, etc.), disinfection is mostly carried out by means of manual cleaning using alcohol-based substances. A system that requires a lot of time and energy and that does not guarantee definitive results.
Given the aggressiveness of the virus, the research group decided to experiment with ozone to sterilize environments and eliminate bacteria, viruses and pathogens.
The results of the experiment have shown that ozone, at certain concentrations and times of application, destroys the coronavirus.
