摘要
新型冠状病毒肺炎(COVID-19)主要通过近距离飞沫传播和接触传播,口罩可以降低感染风险和传播概率,但因医用口罩产能有限,各地政府鼓励企业生产非医用口罩,以满足公众新冠肺炎疫情防控需要。本文介绍我国非医用口罩相关标准,对比分析其细菌过滤效率、颗粒物过滤效率等防护性能要求,提出非医用口罩防护新型冠状病毒的重要指标。同时,分析2020年1月27日—2月25日我国各省公示的102份非医用口罩企业标准,提出疫情防控非医用口罩标准化的建议,以期为相关部门、生产企业及普通人群提供帮助。
Coronavirus disease 2019(COVID-19)mainly transmits through close range droplets and close contact,masks can reduce the risk of infection and the probability of transmission.Due to the limited capacity of production of medical masks,local governments encourage enterprises to produce non-medical masks to meet public needs for the prevention and control of COVID-19 epidemic.This article introduces the relevant standards of non-medical masks in China,compares and analyzes the protective performance requirements such as bacterial filtration efficiency and particle filtration efficiency,proposes important indicators of non-medical masks for protecting against novel coronavirus(2019-nCoV).102 enterprise standards of non-medical masks announced in each province in China from January 27 to February 25,2020 were analyzed,standardization of non-medical masks for epidemic prevention and control are put forward in order to provide assistance to relevant departments,enterprises and general population.
