Seminar 61 -- Quantifying and Minimizing Exposure to Airborne Infectious Diseases in Different Indoor Environments

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Existing evidence strongly suggests that viral infectious diseases can be transmitted via an airborne route across distances in indoor environments. Accordingly, sharing indoor space in the presence of infected individuals poses a major risk in the transmission of the disease. This session will present results of two recently completed research projects. The first project quantified emissions from speaking in a physically distanced conference with overhead HVAC. The second project tested the effectiveness of low-cost interventions to isolate a contagious person from the rest of the occupants in a single family home.
