HIV is spread most commonly by sexual contact with an infected partner, exposure to infected blood through IV drug abuse, maternal to infant, and needle-stick injuries.
HIV/AIDS is a pandemic disease. However, its impact is mostly seen in Africa. Sub-Saharan Africa has about 10 percent of the world’s population but 60 percent of the people living with HIV/AIDS.
More than 3 million Africans were infected with HIV in 2005, representing 64 percent of all new infections globally and more than in any previous year for the improvised continent, according to UNAIDS.
An estimated 4.6 percent of young women aged 15 to 24 are infected with HIV, compared to 1.7 percent of young men (UN).
Save the Children estimated most of the 19.2 million women living with HIV around the globe were mothers and more than 12 million children under the age of 15 have lost one or both parents to AIDS. By 2010, at current rates of HIV infection, this number is likely to increase to 18 million.
Anti-retroviral drugs are being provided to countries in Africa, Asia, and Latin America. However, provision to more and new regimen is urgently needed.
