Which is larger - pore size of condom or aids virus?

AIDS virus, otherwise the condom would not be any protection against it.

if you are referring to the "natural" skin condom then the aids virus is smaller and can penetrate the condom and infect the user. however with latex condoms then the virus cannot penetrate any " pores" because their are not any, (in the same sense) as this is a man made substance Vs animal skin

This is something you can test yourself. Take a condom and fill it full of water. Tie it off at the opening like a water balloon. Leave it overnight. You'll find the next morning that no water has escaped. Water molecules are MUCH smaller than the HIV virus, and so if water isn't escaping, neither will HIV.

The aids virus is smaller than the pore sizeof a condom HOWEVER the aids virus can only survive inside the the cells of other bodily fluids, which are much, much larger than the pore size of a condom.

This is why condoms are effective despite the claims of certain anti-birth control activists.

"Simply put, condoms fail. And condoms fail at a rate unacceptable for me as a physician to endorse them as a strategy to be promoted as a meaningful AIDS protection." -- Dr. Robert Renfield, chief of retro-viral research, Walter Reed Army Institute (3).

"Saying that the use of condoms is 'safe sex' is in fact playing Russian roulette. A lot of people will die in this dangerous game." -- Dr. Teresa Crenshaw, member of the U.S. Presidential AIDS Commission and past president of the American Association of Sex Educators (4).

Condoms aren't safe. In 1993, Dr. Susan Weller of the University of Texas Medical Branch at Galveston reported that an analysis of data from 11 separate studies showed condoms had an average failure rate of 31 percent in protecting against HIV. Dr. Weller reports that "since contraceptive research indicates condoms are about 90 percent effective in preventing pregnancy, many people, even physicians, assume condoms prevent HIV transmission with the same degree of effectiveness. However, HIV transmission studies do not show this to be true. ." Dr. Weller continues, saying "new data indicate come condoms, even latex ones, may leak HIV."
