How is AIDS transmitted and how do you prevent it?

I know that you get it from HIV and you get that from unprotected sex, used needles, breast milk, and maybe drugs/achcol that leads to those things
And preventions are to be abstinence, use clean needles, dont drink breast milk
Am I missing anything?
By the Way, i dont get the whole breast milk thing, can someone explain

oh yea blood, what else?

Well, what you just said is a little bit off. AIDS/HIV is transmitted through bodily fluids. This includes, sperm(explains the reason for sex) blood, breast milk and any other bodily fluids. Breast milk somes from inside the body, so therefore, is would have the HIV/AIDS on it as well. The weird thing is that saliva doesnt apply to this. So the best way to avoid it, is avoid aother peoples blood, and other such things.

any human liquid can transmit aids

any transfer of body fluids., but the aids virus dies when it touches air

use condoms correctly make sure your partner is clean of aids and dont have sex with hookers because you never know where they been

the only way you can get aids from breast milk is if the mother that doing the feeding has aids. like if a mom had aids and she breast fed the child, the child could get aids

Well a mother might not have AIDS when they give birth to the baby but then they so happen to get it after the baby is born, the AIDS is in the milk and then passed onto the baby.

same thing with needles the germs from the other person is on the needle and its getting passed into your body.

The mother passes things like antibodies and diseases through her breastmilk. It's probably because she makes it, and if her body is diseased, then her milk will be diseased.

Saliva, sweat, and urine have not been proven to spread AIDS; just blood, semen, vaginal discharge, and breast milk.

There have, I believe, been only a 5-10 cases of a baby contracting HIV through breast milk. It's very uncommon, like contracting HIV through saliva is near to impossible or very uncommon. In the past you could also contract HIV through tainted blood (my neighbour's husband, a hemophiliac, died from AIDS this way) but this doesn't happen nowadays. There is also a chance of contracting it if you have an open wound and come into contact with infected blood, again very unlikely, though slightly more likely if you're a health care worker. After that the biggest transmitter is sexual contact, then dirty needles

from a mother to her baby is what they mean with breast milk

All human liquid carries the virus. You pretty much have the gist of it.

Those sources you have already listed are correct, except for drugs/alcohol-- that is not a source. Sharing needles (to do drugs) as you have listed is probably what you are thinking about.
Your preventions are correct as well, and, as far as sex goes, your SAFEST way is abstinence, which you will definitely not get it, and then condoms, but I would strongly, STRONGLY recommend you go with your partner to both get tested for HIV/AIDS to make sure that you are both clean, and the reason for you both going and them not just showing you a past test is because one, they could have had more sex without your knowledge, and the tests are anonymous (under the law it is required to be), so you wouldn't know if it were theirs or not.
As for the breast milk, think about it, when one has sex, the reason the HIV/AIDS is spread is by bodily fluids, and breast milk is a bodily fluid as well. I believe (not sure) that it may be spread if a woman is pregnant and has AIDS the baby can get it at birth. Hope it helped.

Aids is curable with dmso, Doctors around the world cure it everyday, it is only incurable in america because the drug company would loose trillions of dollars if they released the cures. And besides, why would the government destroy something that they created for population control.
