Summary

Dr. Peter Palese, a leading virologist, presents a comprehensive briefing on H1N1 influenza (swine flu) to the Congressional Biomedical Research Caucus. He explains the structure of influenza viruses, the difference between seasonal and pandemic influenza, and the historical context of past pandemics, particularly the devastating 1918 Spanish flu. He discusses the 2009 H1N1 pandemic, its origin as a reassortant virus with genes from swine, avian, and human influenza viruses, and its unique characteristics, such as affecting younger populations and being less virulent than initially feared. He highlights the importance of surveillance, vaccine development, and antiviral research. He also presents his laboratory’s work on virus transmission using an environmental chamber, showing that transmission is more efficient at lower temperatures and humidity. The talk concludes with an overview of vaccine types and the need for preparedness.
