text: how the immune ststem works when infected  with hiv.?   when hiv enters the bloodstream it infects cells that are crucial in the immune response to combat the virus. it takes about two weeks for the initial cells to become infected. the amazing thing is that the immune system rebounds and still works quite effectively although the virus exists in the body. think of tracks in a recording studio or screens on a computer. the initial track or screen is the first cells responding. after they become infected they still work but at a very compromised rate. then, a new track or screen starts working to replace the lost cells. after the new track is lowered another track or round of cells begin to respond. you get the idea.  when all the tracks or screens are lowered to a certain point then hiv turns into what is diagnosed as aids.   applying this theory to any disease, it is then logical to say that if a certain track can overcome a microbe we have what is called spontaneous remission.
