“Bird flu” has already shown that it can jump from fowl to humans, and now even to cats, which indicates that it might be the next global killer. But there are many other potential pandemics, and many are not even viruses. Bacteria, prions, parasites, and even environmental factors could suddenly change in a way that slays us.
