[Interspecies transmission of influenza A viruses and influenza pandemics]
Abstract
Molecular and genetic data are summarized on the origin of influenza A virus pandemic variants. Conceptual modifications of the reassortment theory of the origin of pandemic strains are discussed in connection with the appearance of new H5 and H9 avian influenza viruses, which caused the respiratory infection in man and which are presently in the focus of attention as possible agents of future pandemic.
