This seems pretty obvious to me. The rate of AIDS infections in Latin America is skyrocketing and part of the blame certainly lies with the Catholic Church teachings against the use of condoms:
Some 1.7 million people across Latin America are infected with the HIV virus or full-blown AIDS, and the epidemic is spreading swiftly with up to 410,000 new cases in 2006, up from as many as 320,000 new cases in 2004, according the UN AIDS program, UNAIDS.
“In Latin America the use of condoms has been demonized, but if they were used in every relation I guarantee the epidemic would be resolved in the region,” said Alberto Stella, the UNAIDS Coordinator for Honduras, Nicaragua and Costa Rica.
