That's a very good question. During SARS, there was some work on temperature screening, but it was inconclusive, and the information was that it appeared to be ineffective. This occurred over a short period of time. The equipment at the time was not as effective as it is today, so I think that it warrants, in a very speedy fashion, an examination of what the best technology is and whether it works.
One of the things I've noticed with PHAC is a lack of urgency to look at new technologies, to examine the best way to address this, and I think this may be an example.
