    Influenza Research at NIAID

    Each year in the United States, influenza kills more than 36,000 people and hospitalizes 200,000 others. Worldwide, annual epidemics cause about 250,000 to 500,000 deaths. Scientists in NIAID labs, universities and medical research institutions around the world are working together to find better ways to prevent, diagnose and treat influenza. For the latest in NIAID-supported influenza research, please see Recent Scientific Findings.
