There is a novel virus called covid, I know it's novel by the interval for my own immune system to react, and likewise my family. Just like my first exposure to various flu bugs as a child. The best short version is to quote Dr. Luc Montagnier who said it "...represents 800 years of natural mutation from the nearest extant coronavirus. .. The only way this could possibly occur is by manipulation in the lab...". E.g., by frequently cross-infecting various host creature (bypassing the host's natural barriers = injection) with the pathogen(s) to enhance RNA replication errors.
This is the so-called gain-of-function research, and the most difficult part is analysis of the chimeric junk thus produced (if done at all)...
So Anthony Fugazy and his pals in Wuhan are like kids playing with a live hydrogen bomb, if somewhat less cognizant or - infinitely more evil.
