A certain woman, bitten by a dog suspected of having rabies, was immediately rushed to a hospital where she was treated and left in an adjacent room until it could be determined whether or not the dog had rabies.   As you probably know, treatment for rabies is painful and expensive.  If it can be determined that an animal is not infected, it saves a great deal of trouble and anxiety.  An intern on duty explained the seriousness of the situation to the woman, and then was called to other duties.
