James Young on Spreading Disease

James Young talks about the future of emergency. With our increasingly globalized world, uncontrolled disease spreads with more frequency and complexity than ever before. But how can we deal with such emergencies? We must take a preventative approach, James argues. He looks to the spread of the SARS virus to explain the devastating consequences of inert disease control strategy. James discusses the three features of an effective prevention system, how we can learn from past mistakes and what we should strive for in the future.
