The Influenza Virus Enigma

摘要

Both seasonal and pandemic influenza continue to challenge both scientists and clinicians. Drug-resistant H1 N1 influenza viruses have dominated the 2009 flu season, and the H5N1 avian influenza virus continues to kill both people and poultry in Eurasia. Here, we discuss the pathogenesis and transmissibility of influenza viruses and we emphasize the need to find better predictors of both seasonal and potentially pandemic influenza.
