Although 13 cases of cross-species transmission of a simian immunodeficiency virus (SIV) into humans have been reported, only HIV-1 group M has led to a pandemic. Oliver Pybus, Philippe Lemey and colleagues now report a phylogenomic analysis of HIV-1 sequences isolated from central Africa, providing insights into what distinguished the origins and spread of HIV-1 group M (Science 346, 56–61, 2014). | Although 13 cases of cross-species transmission of a simian immunodeficiency virus (SIV) into humans have been reported, only HIV-1 group M has led to a pandemic.

AIDS is arguably the most serious infectious disease to have affected humankind. Not only are an estimated 42 million people carrying the virus at present1, but its case fatality rate is close to 100%, making it an infection of devastating ferocity. In 2002 alone, 5 million people became infected with the causative agent — the human immunodeficiency virus (HIV) — and, of these, 70% live in sub-Saharan Africa. Although a succession of antiviral agents has made HIV/AIDS a more manageable disease in some industrialized nations, and several vaccines are about to enter Phase III clinical trials, HIV will doubtless continue to impose a terrible burden of morbidity and mortality (Box 1). | |||
