Dr. Ronan Glynn:

Ventilation, as I said, is a key aspect in this regard. As a word, it perhaps tends to get left aside. However, when we have talked about elements of our response to the virus, such as having open windows in settings, the use of carbon dioxide monitors and people from different households travelling together in cars at different stages of the pandemic, the importance of ventilation and of there being a safer environment outside rather than inside has been a core part of our public health messaging. It will increase in importance again now as we move into the autumn and winter months. People will be inside more than outside during that time and the importance of ventilation in that context will increase.
