HIV prevention efforts in Mozambique have been hindered by poverty, taboo and sometimes "willfull" ignorance, Reuters reports. An average of 600 to 700 people a day are infected with HIV in the nation, which has 17 million citizens. Mozambique is among the world's poorest nations, where most people have never seen and do not know how to use condoms. In addition, it is considered taboo to talk openly about sex, and many people doubt the existence of HIV/AIDS, making it more difficult to alter sexual behavior.
