Popular question and answer
Problem one
Yesterday, there were 2 new cases of asymptomatic COVID-19 infection in our city. This morning, the official account of "Healthy Luzhou" WeChat released the latest situation of COVID-19 epidemic in our city, saying that the whole city is a low-incidence area. Are there asymptomatic infected people? Why is it still a low-incidence area? What are the prevention and control measures in low-risk areas? Do all staff have to do nucleic acid testing?
Chen Hang, deputy director and deputy chief physician of the Municipal Center for Disease Control and Prevention:
The national standard for risk zoning in COVID-19 is: 1. High-risk area: 2 or more confirmed cases or cluster epidemics occurred within 14 days. 2. Medium-risk area: No more than 10 confirmed cases or 1 case cluster epidemic occurred within 14 days. 3. Low-risk areas: 14 days, no new confirmed cases were found.
As can be seen from the above standards, the following factors are mainly considered in risk area division: 1. Region: streets, towns and villages are the basic units. 2. Time: The longest incubation period in COVID-19 is 14 days. 3. Epidemic situation: the number of cases in COVID-19, and whether there is a cluster epidemic situation.
At present, although there are asymptomatic infected people in our city, they are not "confirmed cases", so our city is still a "low incidence area".
For low-risk areas, the orderly flow of personnel will be implemented in accordance with the epidemic prevention and control policy. We suggest that the general public should maintain normal epidemic prevention and control measures under the current global and national epidemic situation, standardize wearing masks, frequent ventilation, frequent hand washing and less gathering, and pay attention to and abide by epidemic prevention and control measures in various places.
At present, our city has reported 2 cases of asymptomatic infection. However, according to the sample gene sequencing results submitted by the Sichuan Provincial Center for Disease Control and Prevention today, compared with the previous entry case sequences in our province, it shows that the cases were imported from outside the province, found and isolated in time, so the time and scope of activities in our city are limited. After the case was discovered, we promptly investigated and controlled its possible close contacts and sub-close contacts, which minimized the risk of transmission in our city. At present, the city has carried out targeted nucleic acid testing for case activities and people who may have been exposed. The general public and friends can also go to various nucleic acid testing institutions in the city for voluntary testing if necessary.
Question 2
Yesterday, two new cases of asymptomatic infection appeared in COVID-19. How do citizens move in an orderly manner? What should I pay attention to when I come to Luzhou and come back from Luzhou?
Chen Hang, deputy director and deputy chief physician of the Municipal Center for Disease Control and Prevention:
At present, according to the unified requirements of the province, the city's policy on the investigation and management of people coming to Luzhou remains unchanged.
For all entry personnel from the ports of our province, after lifting the centralized isolation 14 days, the local districts and counties will be given closed-loop access at home or centralized isolation for 7 days; After entering Sichuan, people who have been quarantined outside the province for 14 days will be taken to stay at home or quarantined until the entry time reaches 2 1 day.
For those who have lived in the middle and high risk area, centralized isolation shall be implemented until they leave the risk area 14 days.
People who have lived in the towns where the high-risk area is located shall be isolated at home until they leave the risk area for 7 days.
For those who have lived in other towns and villages in the county where the high-risk area is located, home health monitoring will be implemented until they leave the risk area for 7 days.
For those who have lived in other counties in the city where the medium-high risk area is located and in other towns where the medium-high risk area is located, it is necessary to provide negative proof of nucleic acid test within 48 hours, and then conduct 1 nucleic acid test within 24 hours after returning.
It is suggested that all migrant workers in Luzhou should take the exam 1 time after arriving in Luzhou.
For those who leave Luzhou, according to the relevant national and provincial policies, for those who leave Luzhou in Jiangyang District to other cities and prefectures in the province, they need to provide negative proof of nucleic acid test within 48 hours, and then 1 nucleic acid test will be conducted within 24 hours after arriving at the destination; Please consult the destination epidemic prevention policy if you leave Luzhou outside the province.
Question 3
Excuse me, can all schools in the city start school normally? In addition, what are the epidemic prevention and control requirements for students returning from Luzhou?
Xiang Li, member of the Party Group and Deputy Director of the Municipal Education and Sports Bureau:
A: At present, all primary and secondary schools and kindergartens in the city have started classes normally, but some colleges and universities in Luzhou have not returned to school as planned. Relevant colleges and universities are implementing prevention and control measures in accordance with the spirit of higher-level documents and the requirements of the municipal epidemic prevention and control headquarters, actively making preparations, and starting school as scheduled according to the school plan. All kinds of schools at all levels in the city are strictly implementing prevention and control measures such as temperature measurement, code scanning and wearing masks in strict accordance with the requirements of higher education departments and the municipal epidemic prevention and control headquarters, and actively doing a good job in prevention and control of material reserves, environmental disinfection, education and teaching, school safety management, home-school communication and other related work.
For the prevention and control of the epidemic situation of students returning to school in Luzhou, it is suggested that the epidemic situation prevention and control requirements of student schools should prevail. Students should pay close attention to their own health rules and travel rules, and consult their school in time to understand the relevant regulations before returning to school and make corresponding preparations.

In particular, remind the general public and friends to take the initiative to cooperate with the staff to take temperature, scan code and register information. And wear a mask regularly all the time to protect your own safety.
In the next step, the city's transportation system will be deployed according to the municipal epidemic prevention and control headquarters, and epidemic prevention measures will be strictly implemented to ensure that citizens travel in an orderly manner.
