14 + 1:世界卫生组织给出预防疫情扩散的明确数字

随着新学期的开始和春节假期的结束,从受新型冠状病毒疫情影响的地区返回的人数会增多,对于如何预防疫情人传人扩散,有人可能还有疑问。其实不复杂,记住两个数字就行:14 + 1。这是世界卫生组织(WHO)元月20日发布的家庭护理时管控接触的指南[1]中明确提出的。

14天:新型冠状病毒致病的潜伏期时限,也是从受疫情影响地区返回者需要自行隔离的时间。

In view of the limited evidence of human-to-human transmission of 2019-nCoV, persons (including health care workers) who may have been exposed to individuals with suspected 2019-nCoV infection should be advised to monitor their health for 14 days from the last day of possible contact and seek immediate medical attention if they develop any symptoms, particularly fever, respiratory symptoms such as coughing or shortness of breath, or diarrhoea. [1]

1米:避免病毒人传人的最短安全距离,轻症者即使在家隔离也须与家庭成员保持的距离。

The ill contact should be advised to always perform respiratory hygiene and hand hygiene; stand or sit as far away from others as possible (at least 1 m), when in transit and when in the health care facility.

14+1的管控,会给自己和家人造成不便,但为了个人、家庭及公众的健康,值得。
