During that period of time, which was precipitated by David Butler-Jones' stroke and his stepping down, Krista Outhwaite continued as the acting deputy head and I was the deputy chief public health officer. So we separated the role and I focused on the content of the CPHO role and she focused on management. In essence we've been functioning like this for the last two and a half years, which I think has been very effective. I think I've been able to focus on a number of issues as the deputy chief public health officer, H5N1, etc., as we've been moving forward.
All this does in the current situation is stratify and formalize that role of the new CPHO.
