2 HIV EPID SUBSAHARAN AFRICA Sub-Saharan Africa continues to be the hardest-hit area in the world. Only 10% of the worlds population lives in sub- Saharan Africa, But 68% of the worlds HIV-infected, 76% of all AIDS deaths in 2007 occurred in that region. Of the 33 million individuals infected worldwide, 22.5 million are living in sub-Saharan Africa alone. More than one half of the 2.5 million new infections that occurred in 2007 were in sub-Saharan Africa.

3 Cont. All countries in Africa have an HIV seroprevalence rate greater than 5%, with some as high as 25%. In contrast with the developed world, where HIV- infected men outnumber infected women, the majority (61%) of HIV infections in Africa occur in womenan expression of the often highly unequal socioeconomic statuses of women and men in most of the region. Three quarters of all women living with HIV in the world are in sub-Saharan Africa; with a total of 13.2 million, women comprise approximately 61% of infected adults in this region.

4 Cont. AIDS continues to be the single largest cause of mortality in Africa. The HIV/AIDS epidemic has reversed trends toward longer life expectancy throughout much of Africa. For example, until the mid-1980s, life expectancy in Botswana, South Africa, Swaziland, Namibia, and Zimbabwe was increasing; however, the HIV/AIDS epidemic has had a profound effect in the reduction of life expectancy by approximately 13 years in many of these areas. Although somewhat mixed, access to treatment has increased considerably in some sub-Saharan African countries,

5 Cont. the beneficial effects of such increases are starting to be translated into declining numbers of AIDS cases and HIV/AIDS-related deaths. Botswana, for example, has one of the highest incidences of HIV infection in the world, but a successful nationwide rollout of antiretroviral therapy has led to the beginnings of a decline in AIDS-related mortality.

6 HIV IN NIGERIA. In Nigeria, an estimated 3.6 percent of the population are living with HIV and AIDS. Although HIV prevalence is much lower in Nigeria than in other African countries such as South Africa and Zambia, the size of Nigerias population (around 149 million) meant that by the end of 2009, there were almost 3 million people living with

8 CONT. Approximately 192,000 people died from AIDS in 2009.AIDS With AIDS claiming so many lives, Nigerias life expectancy has declined significantly. In 1991 the average life expectancy was 54 years for women and 53 years for men. In 2009 these figures had fallen to 48 for women and 46 for men.
