Wow! That sounds like they got the positive result they wanted but the masses didn't buy into the hysteria like they thought they would.  More than fifty percent gave a fake positive!! I thought that the death toll in china was far lower than they publicly predicted because they wanted people to believe the death toll.  This was being used as a way of killing political dissidents with a massive cover story imho.  If the public had bought this lie we would be in deep shit right now.
