Recently, there has been an outbreak of COVID-19 in China, and more than 1,000 people have been confirmed in Japan, South Korea, and Italy.

The disaster is just around the corner. How should we protect ourselves from infection?

Chinese infectious disease experts advise wearing masks outdoors, especially in densely populated areas.

In fact, at present, all Chinese people wear masks when they go out.

As you can see, thanks to the joint efforts of medical staff and ordinary people, the epidemic has been effectively contained.

So why don't other countries advise people to wear 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 China, people do not need to wear masks in a non-critical situation.

However, I suggest you stock up some masks for emergencies, especially KN95 masks
