No new cases of SARS have been found anywhere in the world for two weeks. A few months ago, SARS looked like it could become a global epidemic. Did we beat it with our aggressive isolation and quarantine measures, or was it simply the summer heat that beat it?
That is an important question. The former means that we may have wiped it out for good. The latter means that it could re-emerge when the weather cools off. The other question is if it could be laying dormant in humans or animals. It’s not time to celebrate just yet.
