Date & Time
COVID-19 has highlighted the importance of understanding how communicable diseases are transmitted
and the relationships between different transmission routes. Exposure modeling is a useful
tool for exploring and describing the fate and transport of viral pathogens in indoor environments.
This presentation will explore examples of exposure modeling used to investigate connections
between air and surface contamination and potential implications for 1) healthcare workers’ occupational
exposures and 2) risk reductions offered by interventions.
- Describe the relationship between aerosol and fomite transmission routes and their relative
contributions to exposures to respiratory viral pathogens
- Review how human behaviors are incorporated into exposure modeling and their importance to
estimating exposures and risks
- Discuss the quantitative microbial risk assessment (QMRA) framework for characterizing microbial
exposures and risks
