Thus, there has been, and still exists, a lively difference of opinion, as to the role played in epidemic phe- nomena, by the concentration of persons not previously attacked. Hamer (1) felt that the number of persons without measles history practically determined (in conjunction with the number of cases present) the number of new cases to be expected in a community in the immediate future. On the basis of this theory, he presented esti- mates, in 1906, of the mean numbers of susceptibles before and after epidemics in London. Brownlee (2), on the other hand, in 1909, gave reasons for believ- ing that susceptibility played only a minor role in shaping the epi- demic cycle, and he pointed to variations in virulence of the infective * Papers from the Department of Biostatistics, School of Hygiene and Public Health, The Johns TI - MONTHLY ESTIMATES OF THE CHILD POPULATION “SUSCEPTIBLE’ TO MEASLES, 1900–1931, BALTIMORE, MD* JF - American Journal of Epidemiology DO - 10.1093/oxfordjournals.aje.a117929 DA - 1933-05-01 UR - https://www.deepdyve.com/lp/oxford-university-press/monthly-estimates-of-the-child-population-susceptible-to-measles-1900-cRtiLHH41a SP - 613 EP - 636 VL - 17 IS - 3 DP - DeepDyve ER -
