If you(guy) have sex with a woman who has AIDS, you used condom while having sex, it is 0.03 mm thick,
do you have chance to get AIDS ?

this is a common misunderstanding...condoms help prevent the spread of HIV...

You could get AIDS even when you wear a condom but The probability of getting infected is very small. Condoms are not 100% efficient they are 97% efficient, the mischance of getting infected is less than 3%.

As Kerrie said, it helps in preventing the spread of HIV.

In other words, it's not perfect, but it's a hell of alot better than nothing.

There is, of course, a virtually foolproof solution...

The odds of a random woman having HIV is quite slim.

The odds of contracting HIV through vaginal intercourse from an HIV infected woman is quite slim.

The odds of condom failure is quite slim.

Put all three together and you've got a vanishingly small chance of contracting HIV from protected vaginal intercourse in a random encounter. Not that it is a good idea anyways.

Note if you have sex once, using a condom, the probability of picking up what she has is (say) .97. If you have sex n times using a fresh condom every time, your probability of not picking up something one of your partners has is (.97)^n. Play around with that on your calculator. How many times for a probability less than 1/2? How many for a probability less than 1/100 - i.e. it's a virtual certainty you have been exposed?

Of course this is tacitly assuming that most of your partners will be carriers. Depending on the environment you move in, that might be accurate or not.
