Latin American & The Caribbean: About 1.7 million people are estimated to be living with HIV in Latin America and the Caribbean combined, including 112,000 newly infected in 2010.
Eastern Europe & Central Asia: An estimated 1.5 million people are living with HIV in this region, an increase of 250% since 2001. The epidemic is driven primarily by injection drug use, although heterosexual transmission also plays an important role.
Asia: Nearly 5 million people are living with HIV across South/South East and East Asia. HIV prevalence is increasing in Bangladesh, Pakistan and the Philippines. In China and India, the two most populous nations in the world, even low prevalence translates into large numbers of people infected with HIV.
Sub-Saharan Africa: Two-thirds of the adults and 91% of the children in the world living with HIV reside in this part of Africa. Swaziland has the highest prevalence of HIV in the world (25.9%).
