Maps were integral to achieving a successful smallpox eradication campaign outcome, for it enabled public health practitioners, and local volunteers to track smallpox cases once discovered, and inhabitants who'd been in contact with such cases using epidemiologically sound science. There were different types of maps that arose during the process, and this was a 'field map' used to geographically map the terrain for each locale. The keeping of detailed records was extremely important, and is one of the hallmarks of properly practiced epidemiologic science. Smallpox cases that were uncovered had to be followed to a successful outcome, as well as anyone associate with close contact with any confirmed smallpox case.
