"Natural disaster" usually refers to something a lot faster-moving--an earthquake, a tidal wave, a volcanic eruption. Something where mother nature flexes her muscles. AIDS is a disease and therefore more of a plague than a natural disaster. And in death toll, I'm sure it can't compare to the plagues of the olden days. AIDS is pretty much contained now, anyway. I have a friend of a friend who's lived with it for something approaching 30 years.
It may be a blessing. Scientists have altered the aids virus to make it attack cancer cells. The news showed a young girl that was cured of lukemia.
Its always been a very puzzling disease,almost unnatural. Its not a disease in its self.It acts on the body's own defences against disease. This is not logical. I have always believed it to be a spore that came off the moon rocks.A disease truly out of this world?
I heard it started in Chad and spent years spreading very slowly. Maybe it increased in infectivity at some point.
If you think having it off with monkeys is natural, then yes....I personally do not.
