I'm not saying it had anything to do with what happened at the border and that we could have spotted it at the border. But my opinion is that once it was discovered we weren't able to round up others fast enough and put them into quarantine. If someone had shown the effects of SARS when they were on the plane, the other people could have been quarantined and watched, and it would have minimized the spread.
