let's talk to mary ellen mccarthy, from the lumen learning trust.e. jon richards from the union unison, they represent teaching assistants, cleaners and caretakers. and in a moment we'll talk to professor saul faust, a specialist in paediatric infectious diseases at the university of southampton who says that it is time for governments to send all children back to school. we're going to ask him about the risk of transmissiosn from children to adults. miss mccarthy festival, good morning. tell us, with yourfive schools, why are you going to only reopen for year six children? my concern focuses on two key risks. one is for the children in early yea rs one is for the children in early years and one is the star. the challenge with early years settings is that the way those very young children learn is with a raft of experiential resources, they touch and they build and get involved, they get their faces down and close to one another. it's very difficult then to strip away all of those learning resources and also adhere to social distancing expectations
