Why mask is necessary to prevent the corona?

.mask is mandatory

• Because we can’t tell who’s infected in the crowd 

• An effective way to limit transmission . 

• It prevents larger droplets from evaporating into smaller droplets that can travel farther

Do masks protect the people wearing them or the people around them?

• The best benefit is for people who have corona to protect them from giving it to other people,

• An healthy person will also be protected from wearing a mask  

  you could still catch the virus through the membranes in  
  your eyes, a risk that masking does not eliminate.

How many people need to wear masks to reduce community transmission?

• You want 100 percent of people to wear masks, but even 80 percent wear it, we would achieve more than a strict lock down.

• The latest forecast suggests that 33000 deaths could be avoided by October 1 if 95 percent of people wore masks in public.

.Hong kong is doing a good job

It has kept its outbreak relatively under control because a vast majority wear a mask

Even if you live in a community where few people wear masks, you would still reduce your own chances of catching the virus by wearing one, 

You should always wear masks and socially distance,
