Emerg Infect Dis. 2002 December; 8(12): 1468–1473.〕 This epidemiologic phenomenon was first identified during measles outbreaks in the 1950s.〔 ==See also== * Compartmental models in epidemiology * Epidemic model * Epidemiology * Force of infection * Mathematical modelling of infectious disease * Transmission risks and rates 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Critical community size」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
