Microphone in hand, this local Bangladesh smallpox eradication team volunteer, was photographed as he was announcing the reward that was made available to those who'd report any smallpox cases. If, indeed, a case was reported, from no matter the source, it was investigated fully, and if confirmed as a smallpox case by an epidemiologist, a reward was paid to the informant, no matter the age, and it was subsequently entered into the 'Containment Book'. The Containment Book was a ledger, which recorded all of the names of anyone living in, or within one half of a mile from a smallpox case, and subsequently all those listed were vaccinated against smallpox. Those vaccinated were followed until a 'successful' vaccination was observed. Periodic surveys showed that by the end of the program, 80% of the public knew about the cash award presented to those who had informed the public health authorities of a confirmed smallpox case.
