The prevalence of HIV in adults reduced from 16.9 percent in 2002 to 14.3 percent in 2007. Females aged 15- 49 are more likely to be HIV positive (16.1 percent) than males (12.3 percent) in the same age group and onaverage become infected earlier. Urban areas have higher prevalence (20 percent) than rural areas (101 percent) . An estimated 1.6% of the adult population becomes newly infected each year, and an estimated 10 percent of HIV transmission occurs during pregnancy, birth or breastfeeding. However, with effective treatment and follow-up, pediatric HIV could be virtually eliminated.
