Abstract: In the last inaugural issue of the Commentary we discussed the origins of the SARS-CoV-2, the probable reasons for its emergence, and how the virus spreads due to the rapid, inter-continental, mass transportation, as well as the human behaviour leading to deforestation and massive urbanization and environmental changes. Here, we outline the issues surrounding infectivity of the SARS-CoV-2, plus its spread through aerosols, droplets and aerosol generating procedures (AGPs) in the dental clinic milieu, as well as its viability in the ambient environment.
