Starting from 00:00 on April 16, the city implemented 4-day temporary social control measures throughout the city. Why is temporary control at this stage? During this period, how should the public cooperate with the epidemic prevention work? The reporter interviewed Wei Xiaoli, deputy director of the Xi'an Municipal Center for Disease Control and Prevention.
Catch the virus "window period"
Reduces the risk of cross-infection
In response to the new measure of temporary control, many citizens wondered why the four-day citywide control should be carried out at this time.
Wei Xiaoli explained that the original strain of this infection is the Aomi Kerong variant strain, which is very contagious and the intergenerational transmission time is also very short, and the temporary control measures are a very necessary arrangement made according to the characteristics of the epidemic, and also in order to completely cut off the transmission chain.
Specifically, there are mainly the following reasons:
The first is that the infected people are mainly freight drivers, and the mobility of this group is very large. In the early stage, the relevant departments carried out some regional static control measures, but they still could not cover all risk points.
Secondly, for some of the risk points announced a few days ago, the risk of transmission is still large, and most of them are located in crowded places, so it is necessary to expand the temporary control area in time. Third, there are three important links in the prevention and control of all infectious diseases, that is, to find the source of infection as soon as possible, cut off the transmission route, and protect susceptible people. At this time, the temporary control measures of 4 days are actually to cut off the transmission route of the virus faster and more accurately and slow down the transmission.
The main basis for determining the 4-day temporary social control measure is to take into account the window period of the virus, that is, the time from infection to detection, which is about 3 to 7 days. Wei Xiaoli added that the last social confirmed case in our city was announced on the 13th, and according to this time calculation, the purpose of this control measure is to achieve the maximum prevention and control effect at the smallest cost.
Do not go out unless necessary
Actively cooperate with nucleic acid screening
The implementation of 4-day temporary social control measures throughout the city is to enable our city to slow down in a short period of time, so that all the sources of infection can be discovered as soon as possible, so that the people can restore normal living order as soon as possible.
Wei Xiaoli said that the temporary social control measures are aimed at reducing the risk of transmission caused by the flow of people and investigating the source of infection that may be hidden around everyone. "This control measure is not to ground everyone, nor is it the rumored 'lockdown', but to reduce some non-essential activities of the public, such as some non-essential social activities and some non-essential dinner activities." Therefore, please also ask the majority of citizens and friends to fully understand and actively cooperate.
Starting from the overall situation of epidemic prevention and control, we should be responsible for ourselves and our families, minimize unnecessary outings and social activities, and reduce the probability and possibility of virus transmission. During this period, the city has also made careful arrangements to ensure the normal production and life of the public, please do not panic, and work together to create a safe and healthy urban environment.
It is reported that the city will carry out another large-scale nucleic acid testing work on the 19th. Wei Xiaoli reminded the general public that nucleic acid testing is very necessary and important, and everyone must actively cooperate, "should be checked thoroughly, not a single person should be missed."
In the process of nucleic acid testing, we should pay attention to personal protection, wear masks correctly throughout the whole process, and children need to wear special masks; during the waiting process, the queues before and after the left and right need to maintain a distance of one meter, and try to talk less and make fewer phone calls throughout the process. "In particular, it should be noted that there is a possibility of droplets on the operating table of the nucleic acid testing site, and everyone should not touch the sampling station with their hands, nor should they put personal items such as mobile phones and keys on the table." If you accidentally touch it, disinfect it immediately with alcohol or disinfectant. "Immediately after the sampling is completed, wear a mask, leave the sampling point as soon as possible, do not stay too long, or ask the sampler about the results of the query and other issues." On the way home, try not to directly touch the stair handrail, elevator button, etc. with your hand, and disinfect your hands in time when you return home to avoid cross infection.
