Viruses which can transmit through the air, are much less capable of doing so in warmer weather, that's why many more people have colds or the flu in winter time. The original SARS-virus disappeared at the onset of spring because much fewer people got infected, mostly because of higher temperatures.
This outbreak is much larger, and the virus seems to be more contagious, but I would have good hopes it will get knocked down by spring to a large extent at least. There are some areas in Asia with pretty large and dense populations which don't have the best healthcare systems, but where the virus (so far) doesn't seem to be able to spread (India, Indonesia), most of the areas where it seems to spread are cold right now, the areas where it hardly spreads are much warmer. Fingers crossed this theory will hold up.
