Xi'an, capital of northwest China's Shaanxi Province, reported 175 confirmed locally transmitted COVID-19 cases on Monday, bringing to 811 the total number of local cases in the latest resurgence since December 9.
 

Of the 175 new cases, 69 were found through mass nucleic acid testing and 105 were found among those in quarantine in designated places, while the remaining case was detected when the person sought medical help, according to a press briefing held by the Xi'an municipal government on Tuesday.
 

Health authorities in the city launched the fifth round of mass nucleic acid testing at noon on Monday in a bid to get rid of as many infections as possible.
 

The Chinese mainland on Tuesday reported 152 new locally transmitted COVID-19 cases, the National Health Commission said in its daily report on Wednesday.
 

Of the new local cases, 151 were reported in Shaanxi, and one in Jiangsu, the commission said.

19天西安本土确诊+811！

已连续3天超150例

从12月9日0时到12月27日24时，本轮疫情西安19天累计报告本土确诊病例811例。其中12月25日至12月27日三天内，西安本土确诊480例。
 

12月28日，陕西省西安市召开新闻发布会，介绍新冠肺炎疫情防控相关情况。
 

12月27日，陕西省委书记刘国中指出，当前，西安疫情防控正处在胶着期，在这个关键节点上做好新一轮核酸筛查，对于精准掌控疫情发展态势、尽快阻断疫情传播链具有极为重要的意义。
 

西安本轮疫情到底是怎么来的？为什么这几天的确诊病例突增？严峻的疫情形势还会加剧吗？这波疫情的拐点何时出现？
 

面对此次西安疫情的几大关键问题，专家们给出了研判。
 

12月27日下午，陕西省疫情防控新闻发布会上介绍，陕西省疾控中心已经完成137例本土确诊病例的全基因测序，均与12月4日巴基斯坦入境航班报告的境外输入病例高度同源。
 

较早前，陕西省卫生健康委员会党组成员、省疾控中心主任刘峰也介绍，本轮疫情感染来源初步判定为12月4日巴基斯坦航班输入，但是具体传播过程尚不清晰，各传播链之间缺少明确关联性，并且陆续在全员核酸检测中发现阳性病例。
 

陕西省疾控中心传染病预防控制所所长张义表示，西安市本次疫情涉及的新冠病毒“元凶”属于德尔塔变异株，感染者数量较多，表现出病毒载量高、传播速度快、发病较为隐匿、传染性强等特点，密接和次密接排查难度大。
 

张义也解释了近期病例突然增多的主要原因，一是加大了核酸检测的力度，增大了覆盖面、提高了检测频率，从而发现了更多的病例；另一个是新出现了一些点状暴发，比如光电谷、京东物流园，短时间出现了不少病例。
