Particles from Respiratory Activities and Infection Spread

The ILAQH has been conducting extensive studies related to infection spread over many years, including responses to the current COVID-19 pandemic. The ILAQH’s work in this field has layed a foundation for the understanding of particles from respiratory activities and infection spread including, the:

  • size distribution and origin
  • mechanisms of breath from human expirated aerosols
  • burden of cough aerosols
  • droplet fate in indoor environments and the impact of room ventilation
  • risk of airborne infection transmission  in indoor environments
  • use of face masks
  • airborne transmission and estimation of airborne viral emissions.
