乌鲁木齐免费核酸检测多数区已基本完成 高风险地区进行二次检测-中新网 中新网乌鲁木齐7月26日电 (记者 孙亭文 赵雅敏)乌鲁木齐市卫健委主任张卫26日在通报乌鲁木齐市最新疫情和核酸检测情况时称，目前，乌鲁木齐全市免费核酸检测工作多数区已基本完成。 国务院专家组和自治区、乌鲁木齐市专家正在根据核酸检测和流行病学调查结果，对疫情的发展做进一步评估。 新疆维吾尔自治区新闻办公室26日召开新闻发布会通报新疆疫情和防控情况。 据他介绍，7月25日0时至24时，乌鲁木齐市新增新冠肺炎确诊病例22例(其中5例为无症状感染者转确诊病例) ，新增无症状感染者38例。 截至7月25日24时，乌鲁木齐市现有确诊病例135例，无症状感染者147例。 25日新增的无症状感染者也基本上都是通过全市免费核酸检测、主动筛查出来的。 乌鲁木齐市卫健委主任张卫26日称，乌鲁木齐全市免费核酸检测工作多数区已基本完成。 他还说，从国内其他地区的经验看，影响核酸检测结果的因素很多，比如检测试剂灵敏度、受检测人员的感染时间和排毒时间、标本取材时受检测者配合情况(配合度差可能导致标本没有取到位)以及检测环境、检验人员的操作熟练程度等。 由于各种原因，核酸检测也会出现假阴性的结果。 所谓假阴性，就是指受检测者确实是感染者，但是核酸检测结果却为阴性。 另外，对于和确诊病例、疑似病例有过密切接触的人员，通常需要两次核酸检测才能排除。 对于去过疫情中高风险地区的人员，如果出现发热和呼吸道症状，一次核酸检测阴性存在假阴性可能，所以也需要两次核酸检测才能排除。 他表示，鉴于以上情况，为了全市各族群众的身体健康，从今天开始，乌鲁木齐市将对天山区、沙依巴克区等重点地区进行二次免费核酸检测，同时开展“查遗补漏” 。 据悉，天山区、沙依巴克区是疫情高风险地区。
Free nucleic acid test has been basically completed in most areas of Urumqi, and secondary test is carried out in high-risk areas – www.chinanews.com Www.wlmq.chinanews.com, July 26 (reporters Sun Tingwen, Zhao Yamin) - Zhang Wei, Director of Urumqi Municipal Health Commission, said when reporting the latest pandemic and nucleic acid test on the 26th day that, at present, free nucleic acid test has been basically completed in most areas of Urumqi. The expert panel of the State Council and the experts of the Autonomous Region and Urumqi are carrying out further assessment on the development of the pandemic according to the results of nucleic acid test and epidemiology investigation. The Xinjiang Uygur Autonomous Region Information Office held a press conference on the 26th day to inform about the epidemic situation and prevention & control in Xinjiang. As introduced by him, from 00:00 to 24:00 of July 25, Urumqi had 22 new confirmed cases of COVID-19 (including 5 confirmed cases transferred from the asymptomatic infection cases), and 38 new asymptomatic infection cases. As of 24:00 of July 25, Urumqi had 135 confirmed cases and 147 asymptomatic infection cases. The asymptomatic infection cases newly increased on the 25th day were basically discovered through the free nucleic acid test and initiative screening in the city. Zhang Wei, Director of Urumqi Municipal Health Commission, said when reporting the latest pandemic and nucleic acid test on the 26th day that, at present, free nucleic acid test has been basically completed in most areas of Urumqi. He also said that, as seen from the experience of other regions in China, the results of nucleic acid test are affected by many factors, such as the sensitivity of test reagents, the time of infection and detoxification of the tested persons, the cooperation of the tested persons when the specimens are taken (poor cooperation may result in the improper acquisition of specimens), as well as the test environment and the operational proficiency of test personnel. False negative result will possibly appear in the nucleic acid test for various reasons. So-called false negative refers to that a tested person is infected actually, but the result of his or her nucleic acid test is negative. In addition, two nucleic acid tests are usually required to rule out persons who have had close contact with confirmed or suspected cases. For persons who have been to medium- and high-risk areas of the pandemic, and have fever and respiratory symptoms, two nucleic acid tests are also required to rule them out since one nucleic acid test will possibly produce the result of false negative. He said that, in view of the above-mentioned situation, for the physical health of the people of all ethnic groups in the city, Urumqi will carry out secondary free nucleic acid test and develop “the check and supplement of omissions” in key areas such as Tianshan District and Shayibake District. It’s learnt that Tianshan District and Shayibake District are high-risk areas of the pandemic.
