disease eradication

Disease eradication refers to the complete elimination of a disease worldwide. This is distinct from elimination, which means a disease is no longer present in a specific region. Eradication efforts involve a combination of strategies, including prevention, control, and the elimination of the disease agent.123

Key strategies for disease control and eradication include:
* Prevention: This involves measures like quarantine, immunization, environmental control, and public education on disease prevention.2
* Exclusion and Avoidance: Preventing the introduction of a disease agent into a host or area.3
* Eradication: Eliminating the disease agent after it has become established. This can involve methods like crop rotation, destruction of diseased plants or alternate hosts, and disinfection.3
* Protection: Shielding the host from the pathogen.3
* Host Resistance: Utilizing or developing resistant varieties of hosts.3
* Therapy: Treating infected individuals.3

Notable successes in eradication include smallpox, which is the only human disease to be completely eliminated worldwide through vaccination and surveillance. Rinderpest was the first animal disease to be eradicated. Polio is also close to global eradication.1
