Elimination and eradication of infectious diseases
This article is a stub. Please feel free to expand it and make it more encyclopaedic.
Elimination and eradication in this context are technical terms with specific meanings.[1]
The Dahlem Workshop proposed the following definitions:[2][3]
- Control: The reduction of disease incidence, prevalence, morbidity or mortality to a locally acceptable level as a result of deliberate efforts; continued intervention measures are required to maintain the reduction. Example: diarrhoeal diseases.
- 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: neonatal tetanus.
- 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. Example: measles, poliomyelitis.
- 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.
- Extinction: The specific infectious agent no longer exists in nature or in the laboratory. Example: none.
