[史上最强传染能力] 气溶胶传播属于空气传播，请各位葱友即刻做好最大防护措施

中国官方卫生部门周六（2月8日）确认新型冠状病毒可以通过空气传染。

上海举行的新闻发布会上，卫生防疫专家确认：新冠肺炎传播途径，除了直接传播、接触传播之外，还包括"气溶胶传播"。

气溶胶（aerosol），是由固体或液体小质点分散并悬浮在气体介质中形成的胶体分散体系。通俗简单来说，气溶胶就是空气中稳定分散悬浮的液态或固体小颗粒，肉眼看不见。

所谓"气溶胶传播"，即飞沫混合在空气中，形成"气溶胶"，吸入后导致感染。

此前的2月5日，中国国家卫健委网站公布的《新型冠状病毒感染的肺炎诊疗方案（试行第五版）》中，对病毒传播途径的描述曾经表示 "气溶胶和消化道等传染途径尚待明确"。

时隔3天后，气溶胶传染途径得到中国官方卫生部门的确认。

气溶胶传染与飞沫传染途径的不同之处在于传播距离。飞沫和接触传染，都是在近距离范围内发生，而气溶胶的传播距离远，增加了无接触感染的风险。

An airborne disease is any disease that is caused by pathogens that can be transmitted through the air. Such diseases include many of considerable importance both in human and veterinary medicine. The relevant pathogens may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, toilet flushing or any activities which generates aerosol particles or droplets. Human airborne diseases do not include conditions caused by air pollution such as Volatile Organic Compounds (VOCs), gases and any airborne particles.

Airborne diseases include any that are caused via transmission through the air. Many airborne diseases are of great medical importance. The pathogens transmitted may be any kind of microbe, and they may be spread in aerosols, dust or liquids. The aerosols might be generated from sources of infection such as the bodily secretions of an infected animal or person, or biological wastes such as accumulate in lofts, caves, garbage and the like. Such infected aerosols may stay suspended in air currents long enough to travel for considerable distances; sneezes, for example, can easily project infectious droplets the full length of a bus.[sup][1][/sup]
