Diphtheria is an acute infectious disease caused by Corynebacterium diphteriae bacteria. Environmental and behavior factors can be a cause of the spread of diphtheria. Objectives: The purpose of the study was to apply the Generalized Poisson regression to identify the factors that influence of diphtheria cases in 2018. Methods: The study used secondary data that had been published by the Provincial Health Office through data from the health profile of East Java Province in 2018. The population was a population in East Java Province in 2018 whose region consisted of 38 districts/cities. The sample in the study was diphtheria sufferers in East Java Province in 2018.
