The term &;disease control&; employs all of the following except

Disease control - reducing the disease incidence to a level at which it is no longer a public health problem. Disease elimination - interruption of transmission of disease, reduction to zero of incidence and continued measures to prevent re-establishment. Disease eradication - permanent reduction to zero of the worldwide incidence of infection by a specific agent. Interventions are no longer needed once eradication has been achieved.
