吸入从防护口罩滤料已经过滤下来的微生物的风险是多少?

Answer 1

The risk of inhaling particles that have been collected by the filter is very low,particularly in very clean areas (such as a patient care setting or a home).When particles are collected on a filter they are strongly held to the filter.Breathing through a filter has not been shown to dislodge the particles collected in that filter.However,it is important to understand that proper use of respirators only reduces your exposure to particles and does not prevent exposure.
这种风险非常小,尤其是在非常洁净的区域（如病人护理设施内或在家中）,当颗粒物被过滤下来以后,它们就被牢牢地留在滤料上了,通过滤料呼吸不曾显示有将颗粒物从滤料上吹下的迹象,然而,重要的是正确使用防护口罩只能降低你暴露的风险,却不能消除暴露.Just because particles may not reaerosolize,does not mean that a respirator can be reused.The CDC has said that it is possible that the virus that causes SARS is spread through touching contaminated objects.Until the spread of the SARS virus is better understood,respirators worn in contaminated areas should be handled gently and disposed of after use according to the facility’s policy for isolation precaution.The
虽然过滤下来的颗粒物不会重新进入空气,但也并不意味着防护口罩可重复使用.
