Abstract

Moates, Anne The prospect of a virulent human influenza pandemic causing large scale mortality and morbidity is a cause for global concern. The most likely candidate is the avian or 'bird' flu which is a strain of influenza virus named because it is found in birds. There are three groups of flu viruses, influenza A, B and C. Type A viruses are able to infect a wide variety of warm-blooded animals. B and C types are mostly confined to humans. Avian influenza is caused by a Type A virus and typically affects birds' respiratory, digestive and nervous systems.[1]
