Everyone wants the schools to remain open. We have seen schools, principals and teachers, parents and children doing their absolute utmost to make sure that happens. I think they will continue to do so but Government has a role to play as well. The Government has not taken its full responsibility seriously. I am talking primarily about the issue of filtration. The Minister for Education has said that natural ventilation is best but there are a few issues with it. It has proven not to be effective to date. Some schools cannot provide natural ventilation. It is cold. We are in the middle of a very cold snap. I have had a child say to me that Mondays are their favourite day because they get to sit beside the radiator on a Monday. I ask the Taoiseach to re-examine the issue of filtration for schools, look at the international expertise, take on board what they are saying and implement a filtration strategy even if it is just on a precautionary basis.

The school authorities, the Department of Education and the Minister have been guided all along by public health advice. In respect of ventilation, there has been guidance issued to the schools advising that the first and most effective form of ventilation is fresh air. I take the Deputy's point that there can be caveats to that in certain conditions. The Minister is providing for technical advice to schools in terms of bespoke measures that might be required in certain school settings around ventilation and that resources will be provided also to facilitate certain bespoke solutions that might be required. Every school is different. About 35,000 CO2 monitors have been issued. I spoke to some teachers the other day. Some are saying to me that it is working in their schools but every school's situation can be different. We will continue to be responsive to measures that schools may require.
