Lethal viruses tend to flare up and disappear. The fact that the outbreak is over does not mean we can pretend it's not a problem, or that it's not coming back. But by identifying the link between SARS and the human population, we can take steps to break that link.

This is a huge question everyone wanted the answer to.

This important research finding is a major breakthrough for the new field of Conservation Medicine, which is a new discipline that brings together health professionals and wildlife scientists to examine links between human, ecosystem, and animal health.

Wildlife populations can act as buffers against the spread of disease as well as sources for its emergence. Through providing a better understanding of how pathogens move among species, the field of Conservation Medicine gives us the tools we need to maintain healthy ecosystems that protect people and wildlife.
