The outcome of over-controlled population. The worst in a human gets suppressed for ages, in critical times it breaks loose. This is just a symptom of a culture that was "normalized" too much.
Just saw a video on titter (pun intended) of two men who got the throat cut because they were from wuhan. Police and all surrounders wear masks. I saw it on the mobile, so i can't post a link. (turkish source, so i can't check). This will probably grow to dramatic dimensions. Mankind is overdue, as it seems.
To anyone who asks himself why ancient higher developed civilizations "disappeared" so quickly...

As far as i remember, the panic level at SARS and MERS or Zika times were way lower than today. "Social" media also contributes to rising fear levels, obviously.

Change a parameter in a complex system, watch the whole thing change in many aspects.
