POPSPaleo-virus impact on AIDS infection Immunity from a multi-million year old virus is helping to increase AIDS infection today. This fits in with an area of thought that sees infection by different agents in an ecological way. There is an understanding that we are regularly infected with the common cold not just because it undergoes these relatively minor mutations from season to season but because there is an evolutionary advantage to not getting full and permanent immunity. Namely the common cold out competes nastier more virulent infections thus it is to our advantage that if we are to get sick, we get sick with the cold virus rather than the other, worse ones.
