Mr. Speaker, the hon. member is right to raise that issue. It was discussed yesterday at an international conference of SARS experts in Toronto.
As Dr. David Heymann, from the WHO said, it is a concern and it is one that the global community is going to take very seriously.
What we need to do is the epidemiological work. We need to look at these patients, case by case, who have allegedly relapsed, and try to figure out why they have relapsed and whether there are certain populations that may be sensitive to relapse.
I can assure the hon. member and all Canadians that we are watching this very carefully, along with the global community.
