If it is a virus, chances are cold preserves it.
I am sure that you can freeze anything.
I am sure a toque, gloves and snow shovel inhibit its ready passing!
Nasty little "things". Their simplicity is their key to keeping us company. Once we have an immune system that has been programmed with the ability to identify it and the white cells eat it up and die in the process of getting rid of it, the problem is solved.
It's been said that at any given time we have 40 immune system magic bullets in our white cell army inside the body. That army continuously issues orders to remove the plans to kill the thing they least see and dealt with the longest time ago in favor of updating the orders to new exposures and reprogramming those white cells to do their job. The problem is that Ebola is not recognized. It's been around a long time and you would think that immune systems would have kicked in by now?
