Last year marked the 50th anniversary of the introduction of the Salk vaccine, which signaled the end of the poliomyelitis epidemic. In the half-century that followed, polio has been virtually eliminated worldwide. With such positive news, it is perhaps unsurprising that the experience of 920 000 polio survivors in the United States, plus the millions more worldwide, has disappeared from society's view. But many people who survived an initial acute attack of polio are still living, and they continue to face old and new problems associated with the virus along with issues related to aging.
