Which disease has seen dramatic reductions due to decades of concerted global effort and is nearing eradication?

Answer

Polio

Polio has been the subject of intensive, sustained global health campaigns that have led to dramatic decreases in cases worldwide. The success seen with polio serves as a primary example of how coordinated public health strategies, including mass immunization, can bring a disease to the brink of eradication, shifting the focus from constant medical management to total elimination.
