This is false, of course. The highest co-factor with AIDS is immorality . A Ph.D. is not required to figure that out. But the world prefers to ignore this simple truth. The moral principles taught in Scripture are for man's own good.
Adulterers are fornicators who violate a marriage, their own or someone else's.
The AIDS epidemic is caused by fornicators and adulterers. This does not mean that all people who have AIDS are immoral. A moral husband or wife can be given AIDS by an immoral marriage partner. Children can contract aids before birth from a mother who is either immoral, or was given the virus by someone who was immoral. A moral person can contract AIDS by means of injection or transfusion, but in that case also, the disease ultimately comes from someone who is immoral.
