This scientific review of mode of transmission of COVID-19 is to aid scientific community in generating hypothesis. The inadequate evidence on SARS-CoV-2 transmission has hindered the development of effective prevention strategy and resulted in continues pandemic of the COVID-19. Therefore, in this review, existing evidence is discussed, hypothesis is generated regarding COVID-19 mode of transmission, and recommendations are forwarded based on existing body of knowledge. Thus, two meters (2 m) physical distance is not completely safe even for large droplets and wearing a face mask is a key in the prevention of SARS-CoV-2 in public areas and confined space and public need to be vaccinated.
