The Other Killer

HIV/AIDS may be the world's best-known virus, the subject of marches, concerts and billions of dollars of aid. With good reason: it killed 1.47m people in 2010. Less noticed, however, is viral hepatitis: it felled 1.44m globally–almost as many as HIV. And viral hepatitis killed more people in 117 of the 187 countries tracked by the Institute of Health Metrics and Evaluation at the University of Washington–including in India, China, Britain and Japan.
