What Should We Do When We Face The COVID-19
Recently, there has been an outbreak of COVID-19 in the world, the disaster is just around the corner. How should we protect ourselves from infection?
The coronavirus that caused this outbreak is the novel coronavirus of the genus β. It is named because of the protruding protuberances on the virus-cell membrane, which is shaped like a crown.
So why don’t other countries advise people to wear face masks instead?
First of all, from a medical point of view, if there are no virus carriers around you, and there is no virus in your environment, then you do not need to wear a mask.
Secondly, the population density of developed countries is low and it is difficult for the virus to spread.
In addition, the medical conditions in developed countries are very good, and they have many ventilators, household oxygen machines and so on to treat patients.
As a result, when half of the output comes from, people do not need to wear masks in a non-critical situation. If and need for the 3 ply face mask pls feel free to contact me!
