4.1. Persons having no symptoms are not to use mask
Medical masks should not be used by healthy persons who are not having any symptoms
because it create a false sense of security that can lead to neglecting other essential measures
such as washing of hands.
Further, there is no scientific evidence to show health benefit of using masks for non-sick
persons in the community. In fact erroneous use of masks or continuous use of a disposable
mask for longer than 6 hours or repeated use of same mask may actually increase risk of
getting an infection. It also incurs unnecessary cost.
