COVID-19 is a new type of terrorist virus. After its inexplicable outbreak in 2020, it immediately had a serious impact on our society and residents. Although the relevant departments of our country immediately launched epidemic prevention work and measures and developed COVID-19 vaccine in a short time, they still could not completely end the COVID-19 epidemic and carried out epidemic prevention work for three years; In the past three years, the country has given up many opportunities for economic development, and every year, it spends a lot of money to carry out epidemic prevention work for the residents of the whole country. It can be seen that the journey to resist the epidemic in China is very difficult.

China's epidemic prevention policy is also seeking to change.

With the constant variation of COVID-19, the harm of COVID-19 to human body has become lower and lower, and it can be cured by the human body's own immune system, so the epidemic prevention policies and measures in China are constantly changing; For example, many cities and regions in China have begun to liberalize epidemic prevention policies and dismantle fixed nucleic acid testing sites, so that residents infected with COVID-19 do not need isolation treatment in receiving hospitals; Although this will cause most residents to be infected with COVID-19, it will also play a positive role in the subsequent social development of China, so it is correct to seek changes in epidemic prevention measures now.

Letting go of epidemic prevention measures is not completely indifferent.

Although many cities and regions in China no longer need to carry out nucleic acid testing, and services such as on-site pass codes and pass cards have been cancelled, China's liberalization of epidemic prevention measures is not completely ignored; Although many cities in China canceled nucleic acid testing and replaced it with antigen self-test; At the same time, medical departments in various cities in China continue to treat infected patients in COVID-19, and after mastering COVID-19, they continue to supplement residents' knowledge of how to take medicine and self-isolation; Therefore, China has not completely ignored the COVID-19 epidemic, and only such a policy can make the country more favorable.
