Regarding the use of latex condoms to prevent Acquired Immune Deficiency Syndrome (AIDS):
One cannot overcome the problem with the distribution of condoms. On the contrary, they increase the problem.
The solution can only be a double one: first, a humanization of sexuality, that is, a spiritual human renewal that brings with it a new way of behaving with one another; second, a true friendship even and especially with those who suffer, and a willingness to make personal sacrifices and to be with the suffering. And these are factors that help and that result in real and visible progress.
The U.S. Centers for Disease Control and Prevention in Atlanta, Ga., said:
Latex condoms, when used consistently and correctly, are highly effective in preventing the sexual transmission of HIV, the virus that causes AIDS. In addition, consistent and correct use of latex condoms reduces the risk of other sexually transmitted diseases (STDs), including diseases transmitted by genital secretions, and to a lesser degree, genital ulcer diseases. Condom use may reduce the risk for genital human papillomavirus (HPV) infection and HPV-associated diseases, e.g., genital warts and cervical cancer.
Overall, the preponderance of available epidemiologic studies have found that when used consistently and correctly, condoms are highly effective in preventing the sexual transmission of HIV infection and reduce the risk of other STDs.
The Pope offered no laboratory studies, medical/scientific theory or epidemiologic data.
