1969er saidThank you. That was bugging me too. It's not the plural of AID. AIDS=Acquired Immune Deficiency Syndrome
You don't contract AIDS, you contract HIV (Human immunodeficiency virus)
Correct. What is contracted is the virus, known as HIV. Which in turn compromises the immune system, leading to a variety of conditions which are referred to as AIDS.
The time it takes for these AIDS conditions or "syndrome" to develop varies greatly. Many factors are involved, from receiving prompt and aggressive HIV medications upon detection, to variables of individual resistance & health issues that doctors & researchers still do not fully understand, nor can reliably predict.
Today we are seeing HIV patients going decades without ever developing AIDS. We see AIDS patients who also continue to live for decades.
