On Wednesday, it was reported by Japanese researchers that small amounts of ozone have the ability to deactivate coronavirus particles. This discovery offers a potential method for hospitals to sanitize examination rooms and waiting areas.

During a news conference, researchers from Fujita Health University confirmed that they have demonstrated the effectiveness of ozone gas at concentrations ranging from 0.05 to 0.1 parts per million (ppm) in killing the virus. These levels are considered safe for human exposure.

In the experiment, a sample of coronavirus was placed in a sealed chamber with an ozone generator. The virus’s effectiveness decreased by over 90% after exposure to low levels of ozone for 10 hours.

The lead researcher, Takayuki Murata, stated that implementing a system that utilizes continuous, low-concentration ozone treatment may be effective in reducing the transmission of the novel coronavirus, even in environments where people are present.

In high-humidity conditions, the researchers observed that the ozone treatment was especially effective.

Ozone, a form of oxygen molecule, is recognized for its ability to deactivate various pathogens. Prior experiments have demonstrated that higher concentrations of ozone (between 1-6 ppm) were effective against the coronavirus.

According to a recent study at the Georgia Institute of Technology, ozone has the potential to be an effective method for disinfecting medical protective equipment such as gowns and goggles.

To decrease the risk of infection in waiting areas and patient rooms, Fujita Medical University Hospital located in central Japan’s Aichi prefecture, has installed ozone generators.

In addition, the university conducted a clinical trial on COVID-19 patients using Fujifilm Holdings Corp’s 4901.T Avigan drug.
