A005 Occupational Hazards to Health Care Providers resulting from Aerial Transmission of Infectious Agents: Droplet size, Temperature, Humidity and Other Factors (Advanced)

Sign up or log in to save this to your schedule and see who's attending!

Topic Overview:

This presentation will focus on aerial transmission of micro-organisms through the air, including multiple factors that contribute to transmission and how to select proper prevention methods. Topics that will be discussed are:

  • Aerosol; large droplets; droplet nuclei.
  • Emission of the contaminated aerosol:
  1. Infected individuals: mechanisms of production; influence on the aerosol/droplet properties; infectious dose.
  2. Environmental sources: humidifiers; cooling towers.
  • Transport of droplets through the air; persistence in the air in relation to droplet size, temperature, humidity, air currents; heat and mass interaction between the bio-aerosol and the air; distance traveled.
  • Time evolution of the microorganism viability.
  • Air currents; air exchange; ventilation; negative pressure.
  • Inhalation and deposition of droplets on the respiratory tract.
  • HEPA filters; simple masks; N95 masks; powered air purifying respirators.
  • Aerosols as biological weapons.

 

Objectives:

  1. Investigate prevention at the sources of aerosols and droplets.
  2. Describe environmental factors contributing to dispersion of droplets/aerosols.
  3. Select appropriate preventive measures against inhalation of infectious agents.
  4. Implement a comprehensive infection control plan adapted to the conditions.
