Can particles, such as bacteria or viruses, be reaerosolized from the respirator filter?
When particles are collected on a filter they are strongly held to the filter. Proper and normal use of a respirator has not been shown to reaerosolize the particles collected in that filter. 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 CDC has recommended that healthcare workers implement standard, contact and airborne precautions when caring for patients with suspect or confirmed SARS.
