More then a Cold?

I came down with a bad cold/flu-ish thing yesterday leaving me holed up in my apartment except for classes. Not fun at all.
What this has made me start thinking of, though, is spiritual warfare. Really. Because right now I feel like there's a lot going on in terms of planning things for World Christian Week and the start of classes in general and I wonder at the timing. I know we in the West like to explain things by natural causes. It's really easy to look at a cold and say simply "duh, it's a cold." But could there also be an attempt here by the enemy?
I was introduced to the concept of the "forgotten middle" a few years ago - this concept that we in the West don't see things as having supernatural causes because we see things as explainable by nature or we simply jump to the concept of God, but those in other countries often will see supernatural cause/effect because between what is seeable and the divine in their worldview stands many angels, demons, etc. Spiritual warfare in other countries, then, is often much more profound where amulets and curses actually have power - not more power then the blood of Christ, though!
But what is spiritual warfare in the West? Are we aware of spiritual warfare or do we avoid the concept all together?
