The Taoiseach has said many times that we must use every tool in our arsenal in regard to Covid-19. I want to ask what is being done regarding all the technologies for proper air ventilation. We know that Covid-19 is spread in the air more so than on surfaces, so ventilation is critical. We need to use better disinfection systems. I have written to the Taoiseach and the Minister recently on this. Ms Orla Hegarty from UCD has been making the point for nearly a year that the future-proofing of ventilation across premises is critical in our fight. There has been much debate about how we are going to get people back indoors over the coming weeks and months in hospitality but also in offices, universities, schools, etc. This is a critical question and one that has been completely underestimated as regards its potential impact. What is the Government going to do to resource, support, influence or direct businesses, social settings and hospitality settings-----

The Deputy's time is up.

-----regarding proper use of new ventilation techniques and technologies?

I agree with the Deputy. Ms Orla Hegarty has done a lot of important work in this regard and in raising awareness levels. My Department has published reports and guidance for public sector authorities and agencies in respect of ventilation. Carbon dioxide monitors have been put in every classroom but we may need to do more. A working group met in regard to schools and recommended carbon dioxide monitors in classrooms and then gave advice on opening windows and so on. We may have to look at that again.

What about new technologies?

We have to look at the new technologies and we will do so. As we come through this phase of Covid, we know there could be a winter phase of Covid. We are very conscious of that. All the tools and technologies at our disposal need to be looked at. I take the Deputy's point.
