It’s reasonable to believe that coughing while being sick will spread a virus all over the place. It’s why people in Asia often wear masks as part of daily protocol.
Why do doctors, dentists, nurses, etc. wear masks? To say that they don’t work, as a blanket statement, is just untrue.
Have you been wearing a mask for the past several years? If not why not?
The Wuhan virus is much smaller than other viruses making your beloved masks much less efficient.

Let me set your ignorant straw-man on fire to disinfect it.
They wear masks and gloves and change them between each patient.
Wearing the same mask for days on end without gloves and following a strict sanitation protocol is useless. It does not work. In fact actually detrimental.
But you go on wearing your little virtue signal.
How else will everyone know how pure and holy you are?
