Hi, is this a promoted post?

I'm not sure that is a reason.

Migrants are "working strength". Thay do everything for less money.

Not really.  I'm not saying the disease is not deadly but its definitely of less concern than something that is already highly infectious, deadly and fully spread like the flu.   Its just about sensationalism in the media and fear-mongering that appeals to xenophobic bias against China.   There are new strains of the flu every year that are much more deadly and aren't covered by the flu vaccine but they hardly get any coverage.  Like, how many of the people criticizing Chinese for eating "strange" animals are actually vegan?  How many of them know or care about the amounts of antibiotic resistant bacteria that come off of animal farms into the human population and kills thousands each year?
