Q气溶胶、飞沫傻傻分不清?A飞沫指人说话或打喷嚏时从口腔中喷出的液体,属于液体颗粒,直径一般大于5微米,八米内就落地了;气溶胶则指悬浮在空气中所有固体和液体颗粒,直径更小,可能能随风飘几百米。总的看来,飞沫传播和气溶胶传播都应引起重视,平时注意个人防护,勤洗手、勤通风、勤消毒,在密闭空间不要随便摘口罩











Q

气溶胶、飞沫傻傻分不清?

A

飞沫指人说话或打喷嚏时从口腔中喷出的液体,属于液体颗粒,直径一般大于5微米,八米内就落地了;气溶胶则指悬浮在空气中所有固体和液体颗粒,直径更小,可能能随风飘几百米。总的看来,飞沫传播和气溶胶传播都应引起重视,平时注意个人防护,勤洗手、勤通风、勤消毒,在密闭空间不要随便摘口罩。
