Pui, 1 computer file (PDF); xi, 129 pages; appendices p. 127-129.The potential involvement of virus aerosols (i.e., airborne virus-carrying particles) in the transmission of human respiratory diseases has led to increased public concern. This dissertation focuses on 1) measurement of laboratory generated virus aerosols as a function of particle size, virus type, and composition of nebulizer suspensions (Chapter 2 and 3) and 2) performance evaluation of filtering facepiece respirators against virus aerosols (Chapter 4 and 5) with the long term goal to better understand and better control the airborne transmission of viral diseases.en-USAerosol particlesAirborne virusesFiltrationInfluenzaRespiratorThesis or Dissertation
