About the Sixth Round of Nucleic Acid Testing to be Launched in Partial Areas of Nanjing
Nanjing is going to launch the sixth round of nucleic acid testing in partial areas and here are relevant questions and answers.
Q: What are the reasons for multiple rounds of nucleic acid testing in Nanjing?
A: Right after the happening of COVID-19 resurgence, we have little idea of the risk related to its infection and diffusion. In this context, large-scale population nucleic acid testing could quickly help us find potential infected person, locate risk areas and groups, and take timely and targeted management and control measures to block the spread of the virus and minimize the chance of exposure to the virus for the public.
There are two main reasons for the need to carry out multiple rounds of nucleic acid testing. First, during the incubation period, it is possible that the virus might not be detected when its concentration is too low to reach the minimum detection limit when sampling because it still requires time for proliferation. Second is its discontinuous viral shedding. At the sampling time point, if there is no sufficient concentration in the collected samples, we will also fail in detecting the virus. When the incubation period and discontinuous viral shedding are superimposed on the large population, a few rounds of nucleic acid testing are simply not enough to locate all infected people. Instead, multiple rounds are needed in order to reach all the infected ones as soon as possible and implement targeted prevention and control measures.
Q: How is the scope of the sixth round of nucleic acid testing decided?
A: So far, Nanjing has conducted five rounds of nucleic acid testing. The first three are city-wide nucleic acid testing, and the rest two are done in partial areas within Nanjing. Following the principle of “more precise classification, more attention to key points, higher efficiency and more focus on quality”, Nanjing COVID-19 Prevention and Control Headquarters will carry out the sixth round of nucleic acid testing in partial areas. Based on the results of the previous five rounds of testing and the epidemiological investigation and contact tracing of each and every positive case, the team of experts have comprehensively analyzed the epidemiological information of positive cases such as their time and space distribution, intergenerational relationship and moving tracks, and determined the scope of the current round of nucleic acid testing.
Q: What is the scope of the sixth round of nucleic acid testing?
A: The scope comprises the following 21 sub-districts (towns):
Jiangning District: Lukou Sub-district, Hushu Sub-district, Moling Sub-district, Hengxi Sub-district, Dongshan Sub-district, Qilin Sub-district, Chunhua Sub-district, Jiangning Sub-district;
Lishui District: Yongyang Sub-district, Baima Town;
Xuanwu District: Xiaolingwei Sub-district;
Qinhuai District: Confucius Temple Sub-district;
Jianye District: Shuangzha Sub-district, Jiangxinzhou Sub-district, Xinglong Sub-district;
Gulou District: Xiaguan Sub-district, Yijiangmen Sub-district, South Rehe Road Sub-district;
Yuhuatai District: Tiexinqiao Sub-district, Saihongqiao Sub-district, Yuhua Sub-district;
Districts can appropriately adjust or expand the scope of testing based on the latest contact tracing and epidemiological investigation results of positive cases.
Qixia District, Pukou District, Luhe District, Gaochun District and Jiangbei New Area are not in the scope of this round of nucleic acid testing.
Q: What is the time arrangement and location of the testing points for the sixth round of testing?
A: The sixth round of nucleic acid testing will start on Aug. 8 in the following districts: Xuanwu District, Qinhuai District, Jianye District, Gulou District, Yuhuatai District, Jiangning District, and Lishui District. The testing will last until 22:00, August 9 in Jiangning District, and 19:00, August 9 in other districts (The specific time arrangement will be determined and announced by each district).
Testing location: See the announcements of districts for details.
Q: How do individuals protect themselves when queuing up for nucleic acid testing?
A: When queuing up at the sampling point, we must keep a safe distance, wear a mask throughout the process, avoid chatting, cover with tissue or an elbow when coughing to minimize the risk of droplet transmission, and carry out sampling in an orderly fashion with the guidance of on-site staff. After sampling, please wash hands or wipe them with hands-free disinfectant immediately, then put on a spare mask. Throw the used mask into a designated medical trash can. Leave immediately and do not spit around the sampling point.
