双语为何北京向阳成为高风险区域官方回应来了

据我国政府网和国家卫生健康委联合供给的“疫情危险等级查询”小程序信息显现，到4月19日18时，北京市朝阳区为高危险区域，成为全国仅有高危险区域。

As of 6 pm Sunday, Chaoyang district in Beijing had a red alert indicating the highest risk classification on the health-tracking app. Other Chinese cities — including Wuhan, the hardest hit city in China during the COVID-19 outbreak; the northeastern cities of Harbin and Suifenhe; and the southern city of Guangzhou — are all marked as low- or middle-risk areas.

到4月19日18时，北京市朝阳区在该健康追寻小程序中被列为赤色高危险区域，而国内新冠肺炎疫情最严峻的武汉市、东北区域的哈尔滨以及绥芬河，还有华南区域的广州市均被标示为低危险或中危险区域。

4月20日下午，在北京市新式冠状病毒肺炎疫情防控作业新闻发布会上，北京市疾控中心副主任庞星火介绍了朝阳区被列为高危险区域的相关状况。

依照国家《关于依法科学精准做好新冠肺炎疫情防控作业的告诉》要求，各地需求根据当地新冠肺炎疫情状况做危险分级和分类防控。

【知识点】

根据国务院应对新式冠状病毒感染肺炎疫情联防联控机制《关于科学防治精准施策分区分级做好新冠肺炎疫情防控作业的辅导定见》中的危险划定规范：

Cities, counties and districts with no newly confirmed cases in the last 14 days are categorized as low-risk regions, those with fewer than 50 cases or those with over 50 but without a concentrated outbreak are classified as medium-risk regions, and those with over 50 cases as well as a concentrated outbreak are classified as high-risk regions.

即以县市区为单位，无确诊病例或接连14天无新增确诊病例为低危险区域；14天内有新增确诊病例，累计确诊病例不超越50例，或累计确诊病例超越50例，14天内未发作集合性疫情为中危险区域；累计病例超越50例，14天内有集合性疫情发作为高危险区域。

照此规范，4月14日，北京朝阳区确诊的一例境外输入性病例（imported case）形成其家庭3人的相关性病例，成为一同集合性疫情（concentrated outbreak）。因而，朝阳区疫情危险等级定为高危险区域。

Up to 62 of his close contacts were put under medical isolation and observation.

该病例的62名密切接触者已进行医学阻隔和查询。

针对这起疫情，北京已敏捷阻隔医治病例，紧密展开流行病学查询（epidemiological investigation）和阻隔密切接触者（isolate close contacts），并对病例同楼相关居民和环境进行了核酸检测，成果均呈阴性。对病例从前活动场所和区域均进行了终末消毒（terminal disinfection）。
