In the battle to eradicate smallpox in India in 1974, finding and containing thousands of outbreaks was the key to getting smallpox under control. In mid 1974, the number of new outbreaks was starting to decrease slightly. The strategy of surveillance and containment - which included a massive workforce, tireless efforts, and rewards for identifying new cases - was paying off. But then we started to notice that members of previously vaccinated families were still coming down with smallpox. We should not have been seeing these new cases.

In 1973 India had thousands of cases of smallpox. For a while they were reporting one thousand new cases every day. Leaders of the eradication effort wanted to solicit help from WHO and bring in physicians, epidemiologists and health worker volunteers from other countries to supplement the Indian teams. But the Minister of Health for India felt that India had plenty of health workers and volunteers to do the job and said that people from other countries were not needed. The Minister's support for the smallpox effort was essential, so the team had to convince him to support bringing in workers from other countries without being critical of the great resources India already had.
