Many called it a hoax or a bio-weapon. If a bio-weapon, then it apparently was lethal to the first few who got it, but it lost its deadliness as it jumped from one person to another until it became a cold or the flu.
It is weird that there is no isolated sample, although many researchers asked for it. So, either there is no isolated sample because it is a hoax or there is no isolated sample because then researcher could then determine it is a bio-weapon.
I guess all these fucking people world-wide got sick, but nobody was able to provide one fucking isolated sample. That is really weird.
