What is HIV cause of or what causes hiv?

HIV is a virus that can only be transmitted in a few ways: by blood, through unprotected sex (vaginal secretions and semen), through breast milk, and through intravenous drug usage (by sharing needles with others using intravenous drugs). It's not airborne, you can't get it by sharing a drink with someone who has it or kissing someone who has it, you cant get it through sweat or tears or anything like that. Those are all some common misconceptions It is kind of unsure exactly how this virus started or how the first person became exposed.

The most acceptable theory to date is that it originated in Chimpanzee's and that the virus was introduced to humans through blood to blood contact.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
