Infection and immunity

Description:

Most people on Earth experience at least one episode of an infectious disease every year. Although the majority recover, hundreds of millions suffer severe or long-term health effects as a direct result of an infection and around 10 million people – many of them children – lose their lives. In the 1960s, it was widely believed that the threat to health from infectious diseases would be overcome by advances in methods of prevention and treatment. Unfortunately these predictions have proved to be optimistic because of the rapidly increasing threat from ‘emerging infectious diseases’.
