Effect of Wearing a Mask

When I had a trip to Myanmar in the beginning of March, I saw many types of masks which non-Japanese people were wearing.
I had no idea what kind of effect they expect.
But most of them, which we can get very easily, would not be able to prevent the penetration of the virus.
If you want to prevent it, you should buy a mask called “Particulate Respirator Type N95.”
This mask is required to get into a ward for tuberculosis patients, because it can prevent the virus penetration.




Then why we’d better wear a mask, even normal ones, to prevent the infection of COVID-19(=Coronavirus).
A mask can be useful to prevent the virus penetration in two ways below.
1. Prevent to be infected through mucosa of eyes, nose or mouth.
In our daily lives, we touch many things which may have the virus. And we naturally tend to touch our eyes, nose or mouth. This can cause the infection.
If we wear a mask, we can reduce the opportunities of touching eyes, nose or mouth directly.
So we can reduce the opportunities of the virus penetration and infection.

2. Prevent droplet infection.
COVID-19 seems not to infect in the way of air infection but infect with droplet infection.
If someone, who has already been infected, coughs or sneezes in front you and you feel any blows of cough of sneezing, you may have high possibility of being infected.
Then wearing a mask can be a great defender for those blows.
You can reduce the risk of being infected.

Of course, none of us knows whether we are already infected of not.
Some people won’t develop the pneumonia even they are infected by COVID-19.
So if you cough or sneeze without a mask, you may be spreading the virus!!
This means that we can reduce the risk of spreading COVID-19 with wearing a mask.

We don’t really have wear a mask like Type N95.
A normal mask works!!
