Abstract

The number of measles cases per million was plotted in linear scale or in logarithmic scale in the vertical axis along years from 1974 to 2021 in the horizontal axis. In the linear scale plot, measles cases persisted with consecutive peaks till early 1990s and then became invisible. In logarithmic scale plot, the plots were horizontally distributed at high level till early 1990s and declined to lower level with ups and downs. Though proportion of measles cases in older population gradually increased over time, as of 2021, the number of measles cases was still correlated with population size of age group
