HIV/AIDS is without doubt the worst epidemic to hit humankind since the Black Death. As of 2004 an estimated 40 million people were living with the disease, and about 20 million had died. Despite rapid scientific advances there is still no cure and the drugs are expensive and toxic. In the developing world, especially in parts of Africa, life expectancy has plummeted to below 35 years, causing a serious decline in economic growth, a sharp increase in orphans, and the imminent collapse of health care systems. The news is not all bleak though. There have been unprecedented breakthroughs in understanding diseases and developing drugs. Because the disease is so closely linked to sexual activity and drug use, the need to understand and change behavior has caused us to reassess what it means to be human and how we should operate in the globalizing world. This Very Short Introduction tackles the science, the international and local politics, the fascinating demographics, and the devastating consequences of the disease, and suggests how we must respond.About the Series: Oxford's Very Short Introductions offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, and Literary Theory to History.
