  4. 4. Health issuesAIDS The global hazard• In 2005 over 43 million people lived with HIV.• In 2006, 3 million people died of AIDS; 5 million more were infected.• Sub-Saharan Africa is the worst affected region: it has 10% of the global population but 60% of the world’s HIV cases.• 75% of all women with HIV live in sub-Saharan Africa.
  5. 5. Health issuesAIDS Sub-Saharan Africa (1)• In 2005 25 million people were living with HIV; there were 3.1 million new infections and 2.3 million deaths.• Only 800,000 people received anti-retroviral (ARV) therapy, a treatment which prolongs life, but is not a cure. The best country was Uganda where 40% of cases received ARV therapy.

Africa is not the only area of the world which cannot afford to treat its population.

  12. 12. Health issuesAIDS The future?Many people now believe that the spread of HIV/AIDS is rooted in problemsof poverty, food and livelihood insecurity, sociocultural inequalities,together with poor support services and infrastructure. It is also believedthat although responses to HIV/AIDS have grown and improved over thepast decade, they still do not match the scale or pace of a steadilyworsening epidemic. UNAIDS itself said, in a report published in 2005, that‘the AIDS epidemic continues to outstrip global efforts to contain it.’
