What role does the environment play in the transmission of respiratory diseases? And how do our interactions in indoor spaces determine the risk of infection?
COVID-19 has presented us with the most difficult healthcare and societal challenge we have faced in living memory. As a new disease, we have had to rapidly build the knowledge base on every aspect of the virus. To understand the mechanisms of transmission we have had to draw on experiences with other respiratory viruses. And the growing evidence based on the SARS-CoV-2 virus.
Understanding the routes of transmission is challenging. But modelling of aerosols, droplets and indoor airflows can play an important role in identifying mechanisms.
Catherine Noakes’ talk outlines some of the approaches used to understand mechanisms for transference and the effectiveness of mitigation strategies. She highlights some of the scientific understanding and how that has changed as we have learned more about the disease.
How is scientific advice used to support policymakers and public messaging? And what are the challenges and complexities in this process?
