Abstract

Viruses are no modern phenomenon, their existence can be traced back for thousands of years. Unmistakeable signs of poliomyelitis have been observed in Egyptian mummies and smallpox, a typical virus disease, was described by the Chinese in the tenth century before Christ. Virologists in the United States working with a virus which appeared unexpectedly in a culture of cat cells, have discovered some curious properties of the virus which have led them to trace it back 10 million years to its probable evolutionary origin in a baboon.
