In May 1966, the World Health Organization was authorized to initiate a global campaign to eradicate small pox. The goal was to eradicate the disease in one decade. Because similar projects for malaria and yellow fever had failed, few believed that smallpox could actually be eradicated, but eleven years after the initial organization of the campaign, no cases were reported in the field.
The strategy was not only to provide mass vaccinations, but also to isolate patients with active small pox in order to contain the spread of the; disease and to break the chain of human transmission. Rewards for reporting small pox assisted in motivating the public to aid health workers. One by one, each small-pox victim was sought out, removed from contact with others and treated.
