In fact, it is not only in Beijing, but also all over the country, especially those who travel by train and other means of transportation. After entering the provincial capital, they have to scan their health codes. The health code can record a person's travel trajectory, and the confirmed population can also take the initiative to know who they have contacted, so as to better prevent and control the epidemic. At present, the epidemic prevention and control not only needs the joint efforts of all of us in China, but also needs scientific and technological products to help prevent and control the epidemic.
In the process of epidemic prevention and control, we can not only see that many places have health norms, but also see that many hospitals adopt new scientific means to treat COVID-19 patients. At the important stage of epidemic prevention and control in 2020, an epidemic broke out in Wuhan overnight, which worried many people. However, with the joint efforts of the whole country, the epidemic situation in Wuhan has been effectively controlled. In this process, many hospitals will make a diagnosis and treatment plan according to the patients' own situation when accepting patients with COVID-19 epidemic.
At present, the development of science and technology in China is very rapid. In the stage of epidemic prevention and control, we can also see the application of many scientific and technological products. At the same time, in our daily life, technology also provides convenience for our life. Especially now, artificial intelligence has been widely used. In many public places, we can see that artificial intelligence has also made some contributions to human work. I believe that with the development of science and technology in the future, the living standards of our citizens will continue to improve. At the same time, we are also very much looking forward to seeing more applications of scientific and technological products in our future production and life.
