The United Nations office reports that a recent study showed that more than 50% of Dominican men of ages 15 to 29 are using condoms when having sex with someone other than their spouses. ONUSIDA, the HIV-AIDS division of the United Nations, says that the disease is widespread in the DR, but the prevalence is declining in response to effective measures taken to prevent its spread. These include alerting Dominicans to reduce their number of sexual partners and to increase their use of condoms. In Santo Domingo, for instance, the prevalence of HIV-AIDS among pregnant women declined from 3% to 1% in the past eight years.
