Cause of HIV/AIDS: The cause of hiv/aids is an RNA retrovirus that infects cells w/a specific target called a CD4 receptor. Many of these cells function in the immune system. Once in the cell, the virus changes to a dna virus ; enters the nucleus of the cell ; binds to the dna becoming part of that cell. It then uses the cells machinery to replicate ; finally kill off the cell ; w/it the immune system of the host.

I would add here since this is an older adult of unknown gender asking this question that in the U.S. one of the fastest rising groups of people getting HIV are post-menopausal women. This sub group of people, I think, may have forgotten that there are 12 STDs and that Pregnancy is not the only thing to worry about when being sexually active.

Know your partner: All adults aged 13-64 should receive an HIV test regardless of risk. Knowing you & your partners HIV status is essential to avoid hiv. Using a condom is essential to prevent HIV & other std's. You may qualify to take HIV medication daily in order to prevent getting HIV if you engage in high risk sexual activity - an HIV specialist is needed for this. Iv drug users should never share needles.

HIV transmission: The virus lives in cells that have a specific receptor site on them called a CD4 receptor. These cells include white blood cells (lymphocytes) ; some of the cells lining our GI tract, some nerve cells... The virus is transmitted in the lymphocytes that are present in body fluids. In the GI tract lymphocytes pick up these viral particles ; in the genital tract micro-traumatic tears allow entry.
