Debate and scientific inquiries regarding airborne transmission of respiratory infections such as COVID-19 and influenza continue. Exposure was investigated under a face-to-face scenario, where people experience the highest risk of respiratory infection. The short-range airborne route was found to dominate exposure during close contact. Based on the fact that most of the outbreaks occurred in indoor environments, we built the link between long-range airborne transmission and short-range airborne route. Results suggest that effective environmental prevention strategies for respiratory infections require appropriate increases in the ventilation rate while maintaining a sufficiently low occupancy.

About the speaker

Miss Wenzhao Chen

Miss Wenzhao Chen is currently a Ph.D. candidate majoring in Mechanical Engineering at the University of Hong Kong. She obtained her Bachelor’s Degree in Process Equipment and Control Engineering from Xi’an Jiaotong University in 2018. Her research interests focus on infection exposure in short range between two people during close contact, including  
  1. Relative importance of short-range airborne route and droplet-borne route.
  2. Implication of short-range exposure on environmental control strategy.
  3. Effects of occupant gestures on exposure.
