IMO CV19 more likely than not originated in a bioweapon lab (50%+ possibility) as an intentionally designed bioweapon and was released by accident before it was fully developed.
I never believed the natural mutation theory. Originally I thought ordinary research in a lab was as or more likely than a bioweapon, but so much information has recently appeared showing a great number of effects desirable in bioweapons that I changed my mind. IMO CV19 most likely was designed from the beginning as a bioweapon.
My personal belief is bioweapon development released before perfected by accident.
Although, maybe it was perfected.
Look at the devastation that has fallen down on us. I suspect many will have long term damage to their bodies. It has so many different symptoms it could hide for awhile.
Children make perfect carriers.
The thing that saved us was shutting down the school system and quarantining people until we could get a handle on all of it.
