An Overview of Destroying SARS-CoV-2 and Proof of the Relationship Between Climate Changes and Airborne Dust on SARS-CoV-2 Prevalence.

Background: In view of Corona pandemic, scientists have taken significant efforts to study and recognize the peculiarities of the SARS-CoV-2 outbreak in order to prevent it from spreading. It was discovered that the virus is spreading in many places and nations that have made significant progress in addressing environmental pollution or are not subject to dusty storms. Infections are growing again in the same country, with varied densities of sick persons depending on the weather and windy season. Methods: Sun and dust are safe techniques for the deactivation and disinfection of SARS-CoV-2. Here, we used metal oxide discs (Fe2O3 9%, SiO2 60%, CaO 6%, MgO 8%, and Al2O3 17%) to safely disinfect SARS-CoV-2 after being subjected to the sun for 30 min. As a result, all SARS-CoV-2 were destroyed completely by transmission electron microscope (TEM) after sun exposure. Three major countries have been chosen as case studies: Italy, China, and Iran. Conclusion: It was discovered that places subjected to dust currents have a lower spread of the coronavirus. This is owing to the fact that the dust contains about 90% metal oxide, which functions as a natural photocatalyst for the synthesis of oxygen and hydrogen. These oxidizing spices can kill SARS-CoV-2.
