Thank you, Llywydd. Minister, you will be aware that a group of organisations wrote to the UK Prime Minister on measures to protect health and care workers from the virus. They say that steps to reduce airborne transmission have been insufficient and they are calling for an improvement in ventilation and for changes in PPE guidance in order to protect the workforce. Will you work proactively in responding to those demands and recognise that our understanding of airborne transmission has changed considerably over the past 12 months and that public health messaging, as well as that protection guidance, should be amended to reflect that, including putting more emphasis on the importance of fresh air?
