If properly worn and used before any genital inter-contact, yes. Pre-ejaculate and other bodily fluids can harbor STDs, although infection (or pregnancy) is far more likely to occur from unprotected sexual intercourse.
The best way to avoid it is not have sex at all. The next best way would be for you and your partner to be tested, try to be as monogamous as possible, and still use condoms. If you feel you must have sex, then doing it with a condom is certainly safer than doing it without one.
I don't know if there is a way to prevent it worldwide, but if you don't sleep with people who have it or are carrying it, or share injected drugs with them, you'll be good.
condoms are only 50% effective,so no they dont really prevent the virus
The BEST way is to not have sex with someone until you have both been tested and both been found to be not infected.
THEN, ALWAYS use condoms.
The best way to avoid HIV and AIDS is by abstinence or (no sex). That way you can prevent any disease like gonorrhea and other diseases.

You can prevent HIV by using condoms and tell your partner to go see a Clinic and take the HIV -antibody test.

Circumcision does NOT prevent HIV and AIDS.
Other than stimulating research into the functioning of the human immune system, HIV is not beneficial in any way.
You prevent aids by not getting infected by HIV. HIV is spread through body fluids. Avoiding sexual contact and contact with blood through sharing needles and transfusions can go a long way toward preventing it.
Don't have unprotected sex and don't share a needle with someone who's HIV positive.

There is no cure for HIV. If there were a cure, that would also prevent transmission.
There is no commercially available HIV vaccine as of 2014.
