Donuel, since the early 50s scientists have been warning that farming conditions in poor countries especially China were laying the world open to strains of flu that could be fatal. They especially warned against allowing pigs and poultry to mix. Pigs eat shit. Even bird shit. Do a search on this. I remember reading an article on this in the early 70s.
Reason for concern? Absolutely. Genetically engineered in a lab? No. Genetically engineered in a pig sty? Very likely.
