Rabies is an ordinarily infectious
disease of the central nervous system, caused by a virus and, as a rule, spread
chiefly by domestic dogs and wild flesh-eating animals. Man and all warm-blooded
animals are susceptible to rabies. The people of ancient Egypt, Greece and Rome
ascribed rabies to evil spirits because ordinarily gently and friendly animals
suddenly became vicious and violent without evident cause and, after a period of
maniacal behaviour, became paralysed and died. Experiments carried out in Europe in the early nineteenth century of injecting saliva from a rabid dog into a normal dog proved that the disease was infectious. Preventive steps, such as the destruction of stray dogs, were taken and by 1826 the disease was permanently eliminated in Norway, Sweden and Denmark.
