How to check key control areas

There are currently 43 key epidemic control areas in China:?

Fuqing City, Fuzhou City, Fujian Province; Yongfeng Street, Songjiang District, Shanghai; Alashankou City, Bozhou, Xinjiang; Ningbo City, Zhejiang Province Beilun District; Huarong District, Ezhou City, Hubei Province, Chongyang County, Xianning City, Dongbao District and Duodao District, Jingmen City, Jiangxia District, Hongshan District, Caidian District, Qiaokou District, Jingkai District, Wuhan City, Tuanfeng County, Huanggang City ; Weidu District, Xuchang City, Henan Province.

Zhengyang County, Suiping County, and Xiping County of Zhumadian City, Huiji District, Jinshui District, Economic Development Zone, Xinmi City, Xinzheng City, Guancheng District, Xingyang City, and Erqi District of Zhengzhou City, Weishi County of Kaifeng City, Yucheng County, Liangyuan District, Suiyang District, and Urban-Rural Integration Demonstration Zone of Shangqiu City; Shifeng District, Hetang District, Yunlong Demonstration Zone of Zhuzhou City of Hunan Province, and Zhangjiajie City. Jiangdu District, Guangling District, Hanjiang District and Hanjiang District Economic and Technological Development Zone, Yangzhou City, Jiangsu Province; Yancun Town, Fangshan District, Beijing, Longzeyuan Street and Huilongguan Street, Changping District; Ruili City, Yunnan Province. Persons coming (returning) to Liaoyang from the above areas must report to their community (village) and will be subject to centralized isolation and medical observation.

Complete the first nucleic acid test within 24 hours, and the quarantine period is 14 days after arriving (returning) to Liaoyang, and two nucleic acid tests will be conducted during this period.

The substance detected by nucleic acid is the nucleic acid of the virus. Nucleic acid testing is to search for the presence of nucleic acid of foreign invading viruses in the patient's respiratory specimens, blood or stool to determine whether he or she is infected by the new coronavirus. Therefore, once the nucleic acid test is "positive", it can prove that the virus is present in the patient's body.

After the new coronavirus infects the human body, it will first reproduce in the respiratory system. Therefore, it can be determined whether the human body is infected with the virus by detecting the viral nucleic acid in sputum and nasopharyngeal swabs. Therefore, a positive nucleic acid test can be used as a new standard for the diagnosis of new coronavirus infection.

All living things contain nucleic acids. Nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The new coronavirus is a virus that only contains RNA. The specific RNA sequence in the virus is to distinguish the virus. and other pathogen markers.

After the emergence of the new coronavirus, Chinese scientists completed the analysis of the entire genome sequence of the new coronavirus in a very short period of time, and by comparing it with the genome sequences of other species, they discovered that the new coronavirus Specific nucleic acid sequences. During clinical laboratory testing, if the specific nucleic acid sequence of the new coronavirus can be detected in the patient's sample, it should be prompted that the patient may be infected by the new coronavirus.
