CADTH COVID-19 Webinar - Community-Based Aerosol Transmission Of COVID-19 and HVAC Systems

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, spreads when an infected person breathes out, sneezes, coughs, or talks, thus putting virus-carrying liquid particles into the air where they can infect other people. Larger particles fall to the ground rapidly, while smaller particles, sometimes called aerosols, can linger in the air. Some infectious diseases — such as measles, tuberculosis, and influenza — are known to spread through heating, ventilation, and air conditioning (HVAC) systems, raising concern that the same may be true of COVID-19. In this webinar, a panel of experts will outline what is known about how COVID-19 is transmitted and discuss what the latest research shows about the potential role HVAC systems play in spreading or mitigating the risk of transmitting COVID-19.
