Lots of disinformation has been circulating about the mask and how it reduces transmission of COVID-19. During the pandemic, politicizing about the usage of mask can be observed also. It can be looked as an unfortunate thing as far as public health is concerned. Science related to public health is quite messy. Novel coronavirus is new virus about which only limited data is available.

N-95 mask is a gold standard as it offers about 95% effectiveness. Mask prevents viral particle inhalation. Therefore, it can be looked as the best option for the frontline workers. They have been working in the high risk areas where viral particle aerosols can be noticed. In terms of effectiveness, surgical masks and face covering made from cloth come respectively. However, it may be good enough to reduce the viral load by even 50%.
