Intentional Contagion - Ignorance
There are a few documented cases where lab DNA altered Pathogens have escaped. The exception not the rule is what I believe.
Stupidity more than intent spreads parasites.
We foolishly keep it from the public eye, and leaders ignore warnings.
For example, Drs warned prior to world war II that GI's would bring back with them
parasites from around the globe. The authority clamped down on
parasite treatment at the time, so it faded from view, and panic did not set in.
Again, prior to the gulf war, I read warnings, specifically about Trypanosome infections. I read countless deaths that occurred in families of GI's that came home. Walter Reed went into high gear, again acting with surprise that this had occurred. Detailed studies and efforts were taken to get some GI's screened and treated years later.
I myself had a Trypanosome infection. Unable to get tested, or the med (I actually got some altered form of med, never tried it). I used naturals formula to cure, involving Thyme, and other things.
If you read of outbreaks in MN in the summer, the CDC like clock work rides off to the rescue to some town or another, to treat people.
I think the old saying applies:
I have met the enemy, and the enemy is us.
