Definition of epidemiology according to the origin of the word, if reviewed the origin of the word epidemiology comes from the Greek word consisting from 3 basic words, namely Epi which means on or about, demos which means inhabitants and the last word is Logos which means Science. So epidemiology is a science that studies about residents. Meanwhile in the modern sense at the time this is a science that studies frequency and distribution (spread) and determinants of health problems in a group of people or society and their determination (factors that influence it).
