西安累计635例，管控升级！为什么近期确诊病例突然增多？

导读 

自12月9日到12月25日，西安市本轮累计确诊病例达485例，加上26日新增的150例，西安市本轮累计确诊病例达635例。西安市疫情防控指挥部决定12月27日12时启动新一轮核酸筛查。同时，为确保新一轮核酸筛查结果的精准度，最大限度减少人员流动，从27日零时起，进一步强化西安市疫情防控措施。为什么近期确诊病例突然增多？

陕西省疾控中心传染病预防控制所所长张义表示，近期病例突然增多主要有两个原因，一是我们加大了核酸检测力度，从而发现了更多的病例。另一个原因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。公众没有必要为这种短期快速上升过于担心，这个阶段通过核酸检测发现越多越好，这也是核酸检测的目的。对于这些点状暴发，我们已快速采取了控制措施，随着封控措施的落实，疫情总体上会趋于平缓。

A citywide lockdown and mass COVID-19 testing in Xi'an, capital of Northwest China's Shaanxi province, have enabled the city to reduce the risk of transmission, but the local outbreak is still developing, local authorities said on Sunday.

The city reported 150 new domestic cases on Sunday, bringing the total number of confirmed infections since Dec 9 to 635.

Most of the new cases were identified among people already being put in quarantine or were detected during mass screening, He Wenquan, a senior Xi'an government official, said during a briefing.

The city completed three rounds of mass testing last week and imposed a citywide lockdown starting on Thursday as the local outbreak continues to spread rapidly, affecting several areas outside Xi'an.

"Most hidden infections and cases scattered in communities have been detected thanks to mass testing programs, which is expected to reduce the risk of the virus' further spread," he said.

A new round of citywide testing will be rolled out on Monday noon.

He added that with more screenings underway, it is likely that daily new infections in the city will remain high over the next few days, but there is no need for panic.

Starting on Sunday evening, the city launched a disinfection campaign, according to the local government.

Virus control measures will be intensified in areas deemed at a particularly high risk of the virus' spread, and supportive measures to ensure the basic livelihoods of residents will also be ramped up, the government said.

The recent outbreak coincides with the 2022 national postgraduate entrance exam that began over the weekend.

Northwest University in Xi'an, one of the largest testing sites across Shaanxi, said that it had arranged over 350 normal testing rooms, and five that met quarantine requirements, in order to ensure students' safety.

As of Saturday, China had fully vaccinated more than 1.2 billion people, according to the National Health Commission.
