Excellent points. The theory that this virus escaped from a nearby lab seems entirely plausible to me and I'm not sure why it's being so easily discounted when, as you point out, the source of the virus has yet to be found. http://www.taipeitimes.com/News/taiwan/archives/2020/02/23/2003731479

The only comments I've seen on this are something along the lines of, "This virus is clearly from an animal source." OK, but that doesn't mean it didn't escape from a lab. So until we determine where it did come from, doesn't it make scientific sense to not exclude any possibilities?

And why isn't the world more concerned with where this came from? Shouldn't we be? If a nuclear bomb exploded in Manhattan, I suspect the first order of business would be to determine where it came from. This virus is probably going to do at least as much damage, and yet that question is not being addressed in the media.
