Why need to wear face mask ?
With the outbreak of novel coronavirus, the CDC sends out news that pneumonia caused by the new coronavirus is respiratory disease, and the spread of droplets is the main way of transmission.
Although the droplets are small and invisible, they are powerful enough to spread.
Experts say that when two people are talking at close range (within two meters), the droplets with virus can directly spray on the mucous membrane of your respiratory tract, eyes, mouth and nose, causing you to be infected with the virus. If the other party sneezes or coughs, the flying distance of the droplets will be longer. The droplets mix in the air to form aerosols, which can also cause infection after being inhaled.
In addition, if the droplets are deposited on the surface of the object, they can be directly contacted with the hands of the polluter, and the contaminated hands can be contacted with the mucous membranes of the mouth, nose, eyes, etc., such as digging the nostrils, rubbing the eyes, etc., which can also lead to infection and thus spread.
That's why experts have repeatedly called for people to wear masks when they go out.
Wearing a mask is not only to protect yourself, but also to protect others.
Therefore, we call on everyone to wear masks in public places! Wear a mask! Wear a mask! Wash your hands when you come back!
I hope the epidemic will pass quickly, every family will be safe and the world will return to normal soon.
