The main emphasis of the course was on the technical strategies for environmental exposure and risk assessment. Dr. Cheung, along with two other panel experts, taught how to use these tools in order to provide a better understanding of data collection and interpretation of the results in support of environmental source identification.

The Course Outline included:

  • Microbiology of Legionella
  • Introduction to Water Systems
  • Assessment of Water Sources
  • Interpretation of Environmental Data
  • Control of Waterborne Pathogens
  • Outbreak Investigation

The Learning Outcomes were:

  • Develop an understanding of the microbiology and growth conditions of waterborne pathogens.
  • Compile knowledge of various water systems that may be impacted by waterborne pathogens.
  • Identify strategies for risk assessments associated with waterborne pathogen contamination.
  • Describe current approaches to controlling Legionella in building water systems.

Viewers will be able to watch a video of this lecture in December.
