Although the spread of COVID-19 in China has been controlled, there will still be some rebound cases. COVID-19 virus is highly contagious. After several months of communication, all countries in the world have been influenced by COVID-19. For some countries that have already controlled the epidemic, how to prevent the epidemic from rebounding is the key work at present. So, what should be done to prevent the epidemic from rebounding repeatedly? 1. Wear a mask in public places * * * Wearing a mask in public places can effectively prevent the spread of COVID-19. Especially in some airports, railway stations and other places with heavy traffic, we must develop the habit of wearing masks, which is not only for our own safety, but also a respect for others. If many people don't wear masks in public places, it may lead to an increase in the spread chain of COVID-19 virus, thus increasing the probability of COVID-19's rebound.

2. Disinfect some places. Disinfection of some public places can eliminate all kinds of viruses in the places. It can not only kill COVID-19 virus, but also kill some other harmful bacteria. Thereby reducing the risk of the spread of various bacteria and viruses. Especially in some high-risk areas, it is very necessary to disinfect some public places regularly, which is very important for people's life and health.

3. Less travel, less participation in gathering activities and less travel can effectively prevent the epidemic from rebounding, but people often have to travel because of the needs of work and daily life. However, on the basis of solving our own life and work, we can go out as little as possible, which can effectively prevent COVID-19's infection. At the same time, try not to attend some party activities. Although the epidemic situation has eased, participating in mass activities will increase the chance of contracting COVID-19. It will cause the epidemic to rebound in some areas.

In order to prevent the epidemic from rebounding, each of us should do our part. It is also a contribution to the fight against the epidemic to take protective measures to ensure their own safety.
