I've been looking into this idea that viruses are produced by the body in order to clean up what the bacteria, etc. cannot. It's very interesting and does make sense to me. The only thing I don't get is when there is an outbreak of a virus, if it doesn't spread, how does an area become infected? Is it simply the environmental factors that give the people who live there the same type of contamination in thier body and therefore they all produce similar viral strains with similar symptoms? That would still make sense to me but seems unlikely you'd have a surge of illness, instead you'd think it would be a steady influx of the illness. Also I wonder how many bad outbreaks of viruses there have actually been, maybe they were all bacterial. Either way I saved your comment for further reading, thanks for posting.
