VIRUCIDAL EFFECTIVENESS REPORT – OZONE GAS NEUTRALISES COVID-19
Article – Medicina – Lithuanian University of Health Sciences – 30th October 2020
Background and objectives: Ozone has been one of the most investigated and discussed sanitization methods. This paper reports a procedure to sanitize air hospital environments, in particular chirurgical surgery rooms that require high levels of disinfection. The purpose of this work was the development and implementation of a cleansing and sanitizing procedure for critical clinical settings with ozone, to prevent hospital infections by the elimination of all toxic and harmful microorganisms in the air, and ensure safe use for operators and patients.
Materials and Methods: The protocol for the study involved a structured selection of a representative environment of healthcare structures such as high, medium, and low-risk settings in air and examples of hospital furniture.
Results: The concentration of ozone was measured during sanitization treatment and the estimation of the total microbial count in the air and on different surfaces before and after the sanitization operations was performed. The results demonstrated a significant reduction in the microbial count that always fell below the threshold value.
Conclusions: Currently, there are no air treatment strategies available for inactivating airborne organisms during hospital outbreaks, which is most probably due to the lack of approved protocols.

(First in World) Conditions for New Coronavirus (COVID-19) Inactivation by Ozone Clariﬁed
A research group of Nara Medical University (Led by Professor Yano Juichi and Director of the Infectious Diseases Center Kasahara Kei) and the MBT Consortium (Infectious Diseases Section member companies: QOL Corporation, Sanyu Shoji Corporation and Tamurateko Corporation) conﬁrmed the inactivation of COVID-19 by exposure to ozone gas for the ﬁrst time in the world. In addition, by experimentally clarifying the conditions for its inactivation, we demonstrated its practicality from an academic point of view.
In order to prevent the spread of infection in examination rooms and meeting rooms, disinfection was performed manually by wiping with alcohol after use, which was labor-intensive and time-consuming.
Ozone gas sterilization was proposed as one of the means to solve this problem, but there was no medical evidence for it.

TOKYO (Reuters) – Japanese researchers said on Wednesday that low concentrations of ozone can neutralise coronavirus particles, potentially providing a way for hospitals to disinfect examination rooms and waiting areas.
Scientists at Fujita Health University told a news conference they had proven that ozone gas in concentrations of 0.05 to 0.1 parts per million (ppm), levels considered harmless to humans, could kill the virus.
The experiment used an ozone generator in a sealed chamber with a sample of coronavirus. The potency of the virus declined by more than 90% when subjected to low level ozone for 10 hours.
Performed by Sany Water Plus device built by Sanity System S.r.l. Corporation.
Ozone is an oxidative gas with disinfectant power stronger than chlorine’s. The oxidation and peroxidation of bio-molecules due to ozone action, produce toxic effects on cells. Indeed, the reactive molecules of oxygen cause damages to cellular lipids, proteins and DNA.
Ozone, inducing a drastic reduction of the quantity of microorganisms, could be used to disinfect water, air and environment.
Aim of the study
The aim of the study was to assess the effectiveness of environment air ozonizing in reducing the quantity of multidrug-resistant bacteria of animal origins.

The Association of Voluntary Public Assistance Croce Verde (Verona branch) uses the ozone generated by the Sany-car tool as sanitization method for ambulances after their use, following the 2-minute protocol for sanitizing environments up to 25m³ as per the tool data sheet.
According to the technical data sheet, the tool is reported to be effective in sanitizing bacteria, fungi, moulds, and inactivating viruses on the surfaces of the medium this is subjected to treatment.
