First of all, the propagation source has been effectively controlled. Since the outbreak of 1 month, the struggle in February, the dawn in March and the success in April, there have been only sporadic cases and no large-scale uncontrollable epidemic areas. For confirmed cases, we have a whole process isolation environment from negative pressure ambulance to negative pressure ward, and we have rich experience in COVID-19, so the source of the epidemic can be effectively controlled. The main contradiction today is to actively guard against imported cases and attach importance to the tracking of asymptomatic infected people.
Secondly, the transmission route of the epidemic has been basically blocked. At present, the habit of wearing masks in public places has been deeply rooted in people's hearts, and the national masks have become the normal state of anti-epidemic, which has greatly hindered the spread of droplets in COVID-19. The health coding system implemented throughout the country gives consideration to personnel mobility and epidemic prevention and control, which not only avoids possible exports in high-risk areas, but also effectively ensures the orderly progress of resumption of work and production. In addition, the policy of tracing the source of confirmed cases and actively isolating suspected cases means that once small-scale transmission occurs, it will attract great attention, and a series of measures such as timely detection, active investigation and close contact isolation can effectively curb the further spread of the virus.
Finally, measures such as suspension of classes and national exercise can effectively reduce the chances of susceptible people being exposed to the virus. The elderly, children and other people with low immunity are easy to be infected with the virus, and their resistance to the virus is often weak. Therefore, promoting online courses and advocating physical exercise can effectively protect such people and avoid the spread of the virus.
It can be predicted that with the deepening of our understanding of COVID-19 and the steady progress of vaccine development, this winter, we will no longer be caught off guard as we were at the beginning, but will be able to control the epidemic thoroughly with scientific methods and effective measures, and let Qi Xin celebrate the New Year.
