Here is the data for the various types of flu in the US

cdc.gov

Each year flu gets "put back in the box" in the spring, only to pop back up in the fall. The graphs are pretty dramatic.

SARS CoV is an RNA virus that causes respiratory disease as do other coronaviruses and influenza viruses. These disease are largely seasonal and occur in the fall/winter. I believe that SARS will follow this pattern. If you look at the influenza chart, they don't even chart weeks 20 to 40 because the virus essentially disappears from the clinical radar screen.

The SARS epidemic ended quite abruptly. Quarantine may have slowed the spread, but I don't think the transmission chain was broken, especially for milder cases, which is clearly demonstrated in Surrey, BC.

So far, no common mutations have be announced and I would not be surprised if none are found. If there are no mutations in Surrey SARS CoV, then the upcoming fall and winter will be quite severe.
