Why another month? Because the facts don't fit your theory this month?
The fact of the matter is that SARS cases appeared in both countries within a few days of one another. Face it, the evil, overpaid US doctors are doing a good job with this problem.
No I will stand corrected on the basis that SARS cases appeared in both nations at the same time. I was of the impression the first US cases appeared about a month after the Toronto case but I have not followed it in detail.
