Recently, 3 1 provinces, autonomous regions and municipalities have newly confirmed cases 16, and 6 cases are local in Yunnan. The epidemic has been repeated and new cases have been found. At this time, how should we do the relevant protective measures? As we all know, since 20 19 and 12, many cases of pneumonia infected by novel coronavirus have been found in all provinces and cities in China. Moreover, with the spread of the epidemic, such cases have been found in various regions of the country and abroad. So far, new cases have been found all over the world, and they are still increasing. In particular, 6 local cases were found in Yunnan Province, China, and everyone was very worried. So back to the topic, how can we effectively defend against virus infection? First of all, from our daily life, daily necessities, articles, or food and other foods and articles must be heated to 56℃ for 30 minutes to effectively inactivate the virus. In addition, the virus mainly spreads through respiratory droplets, which is also the main route of transmission. Of course, it can also spread through contact. Therefore, wearing a mask is a necessary practice and one of the most effective protective measures. Because we don't know who is infected, especially those who are sick or asymptomatic in the incubation period, once they are in close contact, they are easily infected. So for the safety of family and friends, you must wear a mask. Wearing a mask is a very effective way to prevent respiratory droplets from spreading to others, and it is also an important measure to avoid being infected by droplets spilled by others. Of course, we can also avoid infection by going out as little as possible, or not going to crowded places and taking fewer means of transportation such as subways and buses. Especially if someone comes out of a high-risk area, corresponding measures should be taken to avoid infection. In the face of epidemic prevention, our best protective measure is not to take it lightly. Only by being vigilant at all times can we better understand the principle of the virus.
