Purpose
CDC works to improve global control and prevention of seasonal and novel influenza, including variant influenza viruses, and works to improve influenza pandemic preparedness and response.
What CDC does to respond to variant flu
In collaboration with domestic and global partners, CDC's Influenza Division:
- Builds surveillance and response capacity.
- Monitors and assesses influenza viruses and illness.
- Improves vaccines and other interventions.
- Applies research to provide science-based enhancement of prevention and control policies and programs.
CDC influenza programs protect the United States from seasonal influenza and an influenza pandemic, which occurs when a new flu virus emerges that can infect people and spread globally.
