Catholic teaching preaches abstainence until marriage, and also is against the use of condoms. Therefore, all the people who broke from Catholic teaching and had sex with people other than their marital partners, but didn't use condoms, were not using condoms because of Catholic teaching. There's no other reason they didn't use condoms, and it was the responsibility of Catholic missionaries to see that they did.
It's also the fault of Mother Teresa, in India, as well as other Catholic missionaries, that AIDS was "created." The AIDS epidemic is worst in Southern Africa, especially South Africa (5% Catholic) and Botswana (5% Catholic), because Catholicism created the AIDS epidemic and stopped all these non-Catholic people from using condoms.
