It was reported at the meeting that since Xi'an discovered positive infections imported from the province on April 2, as of 24:00 on April 8, Xi'an has 21 local confirmed cases and 1 asymptomatic infection, all of which have been transferred to designated hospitals for isolation

According to the needs of epidemic prevention and control work, on April 6, all districts, counties and development zones in Xi'an City launched regional nucleic acid tests, and 3 positive infections were found in the test in Fengdong New City, Xixian New District; on April 7, 1 positive infection was found in the nucleic acid test in the blocked area (Mengjia Village, Jianzhanglu Street Office); on April 8, 1 positive infection was found among the close contacts in centralized isolation.

Since April 6, Lintong District has found 14 positive infections from people returning from working outside the province who are centrally quarantined.

2. Epidemic handling situation

After positive cases were found, the epidemic prevention and control departments of the municipal, district and county quickly launched an emergency response, and adopted measures such as "fast flow investigation and regional testing" and "upward traceability and downward control" to carry out in-depth flow investigation and traceability, and accelerate isolation control, nucleic acid testing and environmental disinfection.

First, quickly carry out epidemic investigation and investigation, isolation and control. The public security, public health, big data, communications and other departments jointly carried out epidemic investigations, responded quickly and worked continuously, and conducted in-depth and meticulous epidemic investigations and investigations, so as to achieve the fastest possible transfer and separation. As of 24:00 on April 8, Xixian New District had 107 close contacts with the epidemic investigation and investigation, all of which have been quarantined in centralized isolation. 96 people had negative nucleic acid test results, and 11 people had been tested and waiting for release; 187 people had close contacts, and all have been controlled, and all have been controlled. 133 people had negative nucleic acid test results, and 54 people have been tested and waiting for release; 1,618 people had been investigated, and all have been controlled.

Lintong District's close contacts with 178 people, all of whom have been quarantined in centralized isolation. 55 people have been negative for nucleic acid test results, and 123 people have been tested and waiting for release; 232 people have been closed for release, and all have been controlled. 120 people have been negative for nucleic acid test results, and all have been tested and waiting for release; 576 people have been investigated for risk tests, and all have been controlled.

The second is to carry out multiple rounds of nucleic acid testing in a solid manner. From April 2 to April 9, Xi'an City, based on the trajectory of the epidemiological investigation and tracing, based on the trajectory of positive cases, and after expert judgment, five rounds of nucleic acid testing and one round of nucleic acid testing for key areas, risk points, and logistics industries were carried out, with a total of 21.0272 million people tested. Except for the positive people that have been announced, the rest were negative. From 0:00 to 12:00 on April 9, a total of 12.6614 million nucleic acid screening were collected in the city, and 530,700 were detected, and all of them were negative.

The third is to comprehensively and thoroughly disinfect risk areas. As of 24:00 on April 8, there were 34 disinfection and disinfection risk points in Lintong District, with an area of ​​7,005 square meters; there were 17 disinfection and disinfection risk points in Xixian New District, with an area of ​​5,200 square meters.

Fourth, implement temporary control on some areas. According to the epidemic situation, relevant laws and regulations and relevant regulations on epidemic prevention and control, after comprehensive analysis, Xixian New District and Lintong District respectively implemented temporary control of some risk areas starting from April 9, and were lifted after the risk was eliminated.

Next step, we will continue to carry out flow investigation and tracing, risk personnel investigation and control, environmental disinfection and other work; according to the progress of the work, nucleic acid screening for regional and key populations will be launched in a timely manner; comprehensively implement various measures to prevent external imports, and resolutely guard the "two stations and one battle" and other highways entry channels. At the same time, we also ask the general public to do the following work together:

First, please invite the general public to actively participate in nucleic acid testing.The characteristics of the Omickron BA.2 strain are characterized by a certain latency and concealment. During nucleic acid testing, if the virus concentration in the body is not high and is lower than the detection limit, it may not be detected. In order to detect infected people as soon as possible, cut off the virus transmission chain and carry out repeated testing in a timely manner. Nucleic acid testing must be carried out to "test all people should be tested and no one should be missed". We hope that the general public will fulfill their legal obligations, cooperate with community arrangements, actively participate in sampling at the specified time and place, consciously abide by the requirements of scanning codes, wearing masks, and one-meter line, to ensure that nucleic acid sampling is safe, orderly and quickly, and jointly create a healthy and safe living environment.

Second, please continue to understand and support the epidemic prevention and control work. Temporary risk control areas are to quickly, accurately and in-depth epidemic investigations and investigations, protect residents' physical health, effectively block the source of infection and prevent the spread of the epidemic, and eliminate hidden risks as soon as possible. We will mobilize all forces to do our best to provide temporary control of people's living services in the area. We hope that citizens in the temporary control areas will understand and support the epidemic prevention and control work, consciously abide by relevant regulations, maintain good hygiene habits, and take good self-protection. We also ask the general public to continue to understand, support and cooperate with epidemic prevention and control work, consciously abide by relevant regulations, do not believe in rumors or spread rumors, and actively spread positive energy. Every understanding, support and cooperation of yours is adding strength to the epidemic prevention and control work. Let us join hands to eliminate the epidemic as soon as possible.

Q&A session

Q: What are the new characteristics of the current epidemic? What should citizens pay attention to in the next step?

Answer: From 0:00 on April 2 to 24:00 on April 8, a total of 22 positive infections were reported in Xi'an. After comprehensive analysis by our experts, there were two transmission chains for the epidemic in Xi'an: one is the transmission chain of individual logistics workers arriving in Xi'an in another province. A total of 7 positive cases were diagnosed, of which 4 were discovered by social active screening. Except for the first case, the other 3 were found in regional nucleic acid screening organized by Xixian New District; the other 3 were all personnel in centralized isolation and blocked areas.

Another is a transmission chain for migrant workers who returned to Xi'an City from outside the province. A total of 15 positive cases were diagnosed, all of which were found in centralized isolation.

From the perspective of case discovery methods, Xi'an City is actively and effective in carrying out measures such as epidemiological investigation and tracing, investigation and control, nucleic acid testing, temporary closure and control of risk points. The current epidemic situation in Xi'an has shown characteristics such as early discovery, clear transmission chain, and fast response.

In addition, the two epidemic strains have been genetically sequenced and are highly homologous to the virus strain in a highly epidemic-prone area in China. They are Omickron BA.2 strains. It can be judged that they are both local epidemics caused by imported from outside the province.

So in the face of the epidemic, we citizens do not need to panic, but we cannot relax and careless at all.

First, because the virus this time is the Omickron BA.2 mutant strain, which spreads hidden and spreads very quickly. This requires our prevention and control work to be earlier, faster, stricter and more practical. The implementation of all epidemic prevention measures requires the full understanding and active cooperation of our citizens.

2. Maybe everyone has also discovered the activity trajectory of the case announced daily. Among the 22 confirmed cases, many cases have relatively complex activity trajectories before control, involving multiple restaurants, supermarkets, logistics parks, gas stations, high-speed service areas, hot spring bath centers, banks and other places with high epidemic conditions. Because some areas of these places have closed environments, poor ventilation conditions, and long stays, if there are insufficient protection measures for personnel, it is easy to cause the spread of the virus.

In this regard, I hope that our citizens and friends will actively cooperate and do the following:

First, in dealing with emergency epidemics, in order to investigate and block infection as soon as possible, Xi'an will temporarily control some areas. After the risks are eliminated, the control will be lifted in a timely manner according to expert analysis. This will cause inconvenience to citizens. Please forgive me. We thank everyone for their consistent understanding, support and participation in our epidemic prevention and control work.

Second, we publish in Xi'an every day, Xi'an Disease Control WeChat public account and other media at all levels and types of media release information on the activity trajectory of new local cases in Xi'an, nucleic acid testing institutions, and high-risk areas at home and abroad, indicating that people with travel history in the epidemic-related areas, intersection with the trajectory of positive cases, received reminder text messages, and health code turned into "red code" and "yellow code" should actively report to units, communities and hotels. Citizens should actively cooperate with various epidemic prevention and control measures and consciously take good personal epidemic prevention. Starting from now on, once citizens receive relevant risk warning text messages, please report to the local community (village) in time, and actively carry out nucleic acid testing nearby as required, on the premise of taking good protection.

Third, continue to cooperate with the temperature measurement, scanning codes, wearing masks, and maintaining a safe distance of more than 1 meter in various public places, so as to avoid potential cases spreading the virus to other people in these places. In addition, we should gather less and not have dinner together. We hope that citizens can understand these measures and cooperate with us to control the epidemic as soon as possible.

Fourth, the transmission of the Omickron plant is hidden, so we conduct nucleic acid testing in other areas with potential risks in addition to the risk points identified by the epidemiological investigation to detect infection cases earlier and find out hidden risks. Therefore, we citizens should be tested for all tests. If we find that we and our family are at risk of exposure at the same time, we should also actively undergo nucleic acid testing for the sake of our own and our family's health.

Due to epidemic prevention and control,

Ring Expressway Inner Ring Road Seoul Service Area (South District)

Traffic Control

On the afternoon of April 9, a reporter from the Xi'an Traffic Police Expressway learned from the Xi'an Traffic Police Expressway that due to epidemic prevention and control requirements, the traffic control of the Ring Road Inner Ring Road Seoul Service Area (South District) is currently prohibited from entering, and the lifting time is to be determined.

Freight vehicles with parking supply needs can drive through the turn-in lane in the Seoul toll station of Zhuhong Road Interchange into the outer ring of the ring expressway to the Seoul service area (North District). After the rest and supply is completed, enter the inner ring of the ring expressway through the turn-in lane in the Liucunbao toll station of the station of the station of the Ring Expressway to continue driving.
