This has been explained by the fact that a fraction of the population
has mutations in one of the receptor genes that HIV requires to infect
cells (CCR if I recall correctly). So one could be "infected" with
the virus and have very different clinical outcomes based on your
genetic background.

This is explained by the genetic diferences cited.
