New viruses will appear at any time. How should humans prevent it?

At present, COVID-19 is raging all over the world, and its appearance has brought many lessons to mankind. In the future, many people's lifestyles will definitely change because of this epidemic. For example, many people realize that they shouldn't eat wild animals, and it is expected that they should be banned from eating wild animals from the height of legislation. Because many viruses that pose a threat to human health come from wild animals, the SARS virus 17 years ago originated from the Chinese chrysanthemum bat and spread to humans through civet cats. The natural hosts of Middle East respiratory syndrome virus and Ebola virus are also considered bats. The natural host of COVID-19 virus, which is prevalent all over the world, is also wild animals.

Not eating wild animals can prevent some new viruses from infecting humans at the source. In addition, we can also prevent the spread of the virus from other angles. With the popularity of COVID-19 today, many people's living habits have undergone major changes. They know the benefits of washing their hands frequently and how to wash them. Hand washing is a very simple and effective way to cut off the transmission channel of virus, which can not only effectively prevent the spread of COVID-19 virus, but also prevent the spread of cold virus and influenza virus.

At present, some experiments show that many promising drugs are ineffective in COVID-19. Once infected with the virus, there is no specific medicine to kill the virus, basically relying on their own immunity to remove the virus. If there is a vaccine, it can be vaccinated in advance, but it will take at least one year for a new virus like COVID-19 to appear. It is basically impossible to improve one's immunity with drugs. Strengthening physical exercise is a good way to enhance immunity. After the epidemic, people who run in the morning are likely to become more than before.

Develop good hygiene habits, wash hands and faces frequently, and strengthen physical exercise. Even if a new virus comes, human beings will be more confident to defeat it than they are now.
