Modern Influenza Science Case Studies
Complex Preparedness for a Complex World
Influenza pandemic preparedness has advanced significantly since 1918. Our ability to prepare for and respond to influenza threats has evolved over time in a complex political, social, and cultural context.
While we are much better prepared to combat influenza threats than 100 years ago, there is still room for improvement. The 2009 H1N1 pandemic reminded us that the geographical and biological origins of an influenza pandemic remain highly unpredictable. In recent years, outbreaks of avian and swine influenza viruses among people have demonstrated the ever-expanding interactions of human health and animal health. Limitations persist in current surveillance, vaccine production capabilities, vaccine effectiveness, and our ability to predict how the virus will change.
To address such challenges, public health scientists at CDC and its global partners work each day to improve methods for preventing and controlling seasonal influenza, which is the foundation for any response, including the global response needed for an influenza pandemic.
