Rapid method for mapping morbidity and mortality during epidemics

A rapid method for mapping health information during epidemics is described. We divided maps of cities into coded squares and assigned a code to each street which corresponded to its location on the map. Thus, health data information could be easily transferred from the field by indicating the number of cases in each square and readily transferring this information onto a map. By applying density data of the civilian population in each neighborhood it was possible to calculate incidence and prevalence rates at any given time.
