Educational Resources

Seasonal influenza infects millions of people and causes thousands of hospitalizations and flu-related deaths each year, which is why the National Institute of Allergy and Infectious Diseases (NIAID) is working to improve how we fight the flu. This page provides links to several useful influenza-related resources from the United States Government and other global experts. 

Influenza Treatment and Medical Response

NIAID works collaboratively to support organizations, such as the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), which lead the response to seasonal influenza outbreaks and pandemics as they occur in real-time. To find out more about influenza treatments and medical responses, visit the pages provided below. 

  • CDC Influenza Page

    CDC's main page on influenza contains information on flu prevention, symptoms, diagnosis, and treatment. The CDC’s page also includes information to promote influenza infection prevention.

  • is a database of privately and publicly funded clinical studies. For each clinical trial, this database provides a study description, study design, and additional clinical and experimental metrics to the public.

  • WHO Influenza Page

    WHO's main page on the Global Influenza Programme (GIP) provides strategic guidance, technical support, and coordination of activities to national governments to support preparedness for seasonal, zoonotic and pandemic influenza.

Influenza Epidemiology

During the influenza season, public health organizations such as the CDC and WHO, publish regular disease surveillance reports with information about the number of influenza cases identified. To find out more about the number of flu cases that have been reported, please see the links below. 

  • CDC Influenza Surveillance Report

    CDC's weekly surveillance report provides in-depth public health information on the number of positive influenza cases, disease severity, the virus types and subtypes being detected, and characterization of the viral strains identified.


    WHO’s Global Influenza Surveillance and Response System (GISRS) is a platform for surveillance, preparedness, and response for seasonal, pandemic, and zoonotic influenza.
