there is more to the story that is not being released.
There are a number of conspiracy theories floating around:
1.) This is a bio-weapon that got released accidentally.
2.) It seems more lethal for men than women, so perhaps this was an engineered virus released on purpose to bring the male/female ratio in China back in-line.
Of course I’m not aware of any evidence supporting either of these theories, but something seems amiss with the response based upon the information reported.
