Mr. Jim Breslin:

An important caveat is that I am not giving a public health assessment because I am not a public health doctor. Within the Department of Health and the Government, everybody is on the record as saying the roadmap is just that. It is a living document and based on our travel and how we get along we can adapt our decision-making at various stages. It is important the three-week windows are built in to review each stage but it means, in light of our experience and that of other countries, we can act where we see new evidence around risk. For example, if something is in stage 4 because it is seen to be a high risk but evidence indicates it is a lower risk, it can be reviewed and evaluated as we go along.
