Disposable protective masks are a symbol of the era of pandemic ¨C a visual metaphor for tiny, invisible viral enemies hiding in any corner. Some choose to wrap the face around the scarf, while others choose to yank the T-shirt over their mouth.

A cough can produce up to 3000 drops of germs. Some people worry that the virus can also be spread by speaking. A recent study has shown that we can spray tens of thousands of water droplets that are invisible to the naked eye into the air just by saying "keep healthy".

At the same time, the behavior of virus-filled droplets in air-conditioned rooms is poorly understood, and it is thought that they will deposit on the surface faster in the disturbed air. There are also reports that coronavirus can spread through the building's ventilation system.

Although the mask may bring some discomfort and make it more difficult to find the facial expressions of the person being interviewed, these things are not a small price for keeping the safety and health of those around us.
