Secondly, a bioweapon doesn't have to kill to be effective. It can be intended to paralyze the target country with debilitating illness.
Third: by its nature, a bioweapon isn't likely to behave exactly how its developers want, especially one that's released accidentally, which would likely mean it's a work in progress that was just being tested, not a final product.
It's hard to be sure it's a bioweapon, but there are a lot of reasons to be suspicious, starting with the fact that it emerged in the city with China's only dangerous virus lab, and was initially pubicly blamed on a market only 300 yards away from that lab. That's one hell of a coincidence.
