UVGI (incl. use of split AC)

    • Scope: 24 Priority countries + Global?
    • Focus: NTP, NGOs, etc
    • Objectives:
      • Describe the concept of UVGI
      • Describe UVGI in the context of updated WHO guidelines
      • Describe split air conditioning units and the role of UVGI in reducing TB transmission in these settings
    • Expected Outputs/Outcomes: After attending the webinar, participants will be able to
      • Describe the concept of UVGI including implementation, monitoring and evaluation
        • What is UVGI?
          • A supplemental environmental control to ventilation methods
          • A standalone environmental control measure
          • An administrative control
        • Describe the relevant WHO guidelines
          • Are UVGI concepts included in the WHO guidelines?
            • Yes
          • Describe split AC units, associated TB transmission risks and the role of UVGI in reducing TB transmission
            • Are split AC units helpful for TB control?
              • No
            • Detailed Outline
              • Intro/Purpose
                • Describe environmental controls, especially natural ventilation and UVGI
                • Describe UVGI (esp as an essential supplement to natural vent.)
                • Measuring UVGI implementation
                • Make a case example of ductless/split AC and the growing urgency of GUV implementation
              • Environmental Controls
                • Natural ventilation
                  • Pros
                  • Cons
                • GUV
                  • Pros
                  • Cons
                • Not an either/or, but rather supplemental/complementary
              • Measuring UVGI implementation
                • Discuss available indicators
                • Discuss challenges/successes in measuring UVGI
              • Case example: Ductless/split AC and the need for UVGI
                • Split/ductless AC recycles air in the given space (i.e. a waiting room)
                  • Describe the data on this
                  • Describe the specific UVGI solution (upper room!)
                • Describe cost effectiveness of GUV compared to other air cleaners
              • Way forward: GUV as an essential environmental control
                • Advances, research etc.
                • Safety
              • Questions
              • Conclusions
    • Date and Time: July 30, 2019 Time – TBD
