"Viruses typically are not really living organisms per se. They are complex bio-molecules that need a living cell to be active. In order to be safe, as we still do not really know how long these coronavirus can survive on surfaces, its best to disinfect areas that have lots of contact with people whether or not they are showing signs of having been infected or not. One good way to do that is by deploying ozone gas. Ozone gas has been proven to kill the SARS coronavirus and since the structure of the new 2019-nCoV coronavirus is almost identical to that of the SARS coronavirus, it is relatively safe to say that it will also work on the new coronavirus. There are more than 17 scientific studies that show Ozone gas is able to destroy the SARS coronavirus."

"Ozone, an allotropic form of oxygen, possesses unique properties when it oxidizes or interacts with chemical and biological systems. Ozone, best known for its protective role in the earth’s ecological environment and its interaction with industrial pollutants, has bactericidal, virucidal, and fungicidal actions that have been used in water treatment, odor control, and medicinal applications. Ozone [O3], a powerful oxidant reacting with organic molecules containing double or triple bonds, yields many complex byproducts. It is this property of ozone that has been applied as a disinfectant and sterilant against bacteria, viruses, and fungi."
