What is disease elimination?

  • Elimination of disease:

    Reduction to zero of the incidence of a specified disease in a defined geographical area as a result of deliberate efforts; continued intervention measures are required. Example: elimination of wild polio in Nigeria.

  • Elimination of infections:

    Reduction to zero of the incidence of infection caused by a specific agent in a defined geographical area as a result of deliberate efforts; continued measures to prevent re-establishment of transmission are required. Infections can be reintroduced as long as the disease is present in other parts of the world. Example: measles, poliomyelitis in the Americas.

What is disease eradication?

  • Eradication:

    Permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate efforts; intervention measures are no longer needed. Example: smallpox.
