The common cold is a ‘coronavirus’. There are many iterations, and they go through billions of mutations as it is replicated in cells in the body and pass from person to person. Therefore at any given time it is possible to capture a ‘novel’ iteration of this in the virus mutation stream, that ‘has not been seen before’.
Add some powerful propagandistic elements to the media and politicians that you have bought and captured and a you have turned the common cold into a powerful, ‘BIOWEAPON’ capable of holding the entire global economy hostage.
