I believe the Canadian Blood Services has provided some of the response to this question as well.
There has been no evidence to date of any Lyme disease in the blood supply. While not every blood donor is tested, Canadian Blood Services screens out people who are sick. They also do studies intermittently to look at the donor group. They haven't found any evidence.
I also want to go back to the fact that we are investing $4 million in research, together with CIHR. Some of the investments are in diagnostics. Some of the investments in other areas of research will bring us more evolving information.
