It actually invades the cells and destroy it.
2 :
because it's an immune deficiency. it attacks the immune system specifically. people don't die of the disease itself, they die of illnesses they get because their immune system is compromised.
3 :
HIV/AIDS destroys all the white blood cells and eventually you will have no more protection from the virus. But why do you care? You're a ninja right?
4 :
HIV is a virus that colonises the immune system It clones itself inside your body and KILLS your immune cells. It continues to kill your immunity until your whole system is dead. Once your immune system is dead you then have AIDS (auto immune deficiency syndrome). Your body no longer has any protection against viruses and bacteria.

Gradually breaks down the bodys defence system over time that the simplest diseases can attack or kill you without the proper treatment that is lol thank you gets in the cells that defends you from illnesses and fights off infections manufactures more of itself till no defence left at all anti retro viral therapy helps thoughT Cells level of gets monitored daily of the person

Your white blood cells have a role in the immune system to attack against invaders and I believe keep a memory of the invader, so if that specific invader attacks again, it won't affect you; it will be eliminated as soon as possible. However, when the HIV/AIDS virus enters into your system, the white blood cell can't wrap itself around the virus to fight it and keep a memory of it, so the virus enters into the white blood cell to multiply, thus destroying it. I think that's how it goes, anyway. So basically, you have less white blood cells to fight against invaders, and the invaders stay in your system longer, causing more damage than necessary. See, all HIV/AIDS does is lower your immune system respone, so it's really the common cold that can give you the final blow; or at least a long one, anyway.

Here for the point :) all I know is that yes it does weaken the immune system by killing off the white blood cells but that's it good luck

Here you go...Acqired Immune Deficiency Syndrome is caused by HIV which enters your T4 helper cells. These Lymphocytes are part of your white blood cells which help T4 helper cell help stimulate the B cells (subset of Lymphocytes) to make Immunoglobulins, but when the T4h cells are infected they can't stimulate the Bcells to make immunoglobulins and eventually certain oppertunistic diseases are able to infect the host. In a nut shell.

Check out the Wikipedia entry for HIV. It does a pretty good job of explaining the retrovirus and how it affects the human body. There are also several good graphic illustrations of the replication process.
