HIV/AIDS: A Very Short Introduction provides an introduction to AIDS—the most serious human epidemic in centuries—tackling the science, politics, demographics, and devastating consequences of the disease. The first case was identified in 1981; by 2004 approximately forty million people were living with the disease, and about twenty million had died. The outlook today is a little brighter. Although HIV/AIDS continues to be a pressing public health issue, the epidemic has stabilized. The worst affected regions are Southern and Eastern Africa. Elsewhere, HIV is found in specific, often marginalized populations. Although there remains no cure for HIV, there have been unprecedented breakthroughs in understanding the disease and developing drugs.
