Since the outbreak of Severe Acute Respiratory infection (SARS) ten years ago, efforts to detect unusual severe respiratory disease have intensified. At the same time, there have been major advances in the development of diagnostic tests. This is a result of a major increase in the research and development budget for tests to diagnose unknown disease, and this investment was driven by the perception that anthrax and other organisms such as the smallpox virus will continue to be a bioterrorism threat.

When disease detection efforts are intensified, surveillance systems often become better at picking up illness that would have otherwise gone undetected until enough people developed the disease that an outbreak occurs and is noticed. Throughout history, mysterious severe respiratory infections that have resulted in death have emerged, but with new diagnostic tests it is also now possible to determine the cause of such disease, often soon after it is detected.
