In 1996, British doctors were horrified to discover that mad cow disease (BSE), an affliction that had been plaguing British cattle for ten years, had jumped the species barrier and was appearing in humans as variant Creutzfeldt-Jakob disease (vCJD). Not unlike the mad cows, victims of vCJD suffer from a degenerative neurological disease that peppers the brain with microscopic holes, causing dementia, loss of motor control, and certain death. What alarms researchers and public health officials worldwide is that the incubation period for vCJD may be as long as 10 or even 15 years, and during this period those infected are symptom-free. And because the disease is so far undetectable except by autopsy, there is no way of knowing with certainty how many people have already been infected. In fact, even travelers who spent time in the U.K. from the early 1980s through the mid-1990s are still considered to be at some risk. What's more, although the U.S. has not detected any mad cows within its borders, there are plenty of "mad deer" running free in several states, and the disease afflicting them is a BSE-type neurological disorder. Called chronic wasting disease (CWD), the illness in these deer has yet to be linked with any human deaths. But given BSE's ability to jump species, there are no guarantees.
