− | There are three etiological factors of diseases - [[asatmyaindriyartha]] samyoga (incompatible contact of the sense organs with their objects), [[prajnaparadha]] (intellectual error), and kala parinama (being out of harmony with the rhythms and cycles of nature). [Cha.Sa.[[Sutra Sthana]] 11/43]. Kala parinama may occur in three ways: firstly, atiyoga, i.e, by over-manifestation of a season (e.g. excess raining in rainy season), secondly, ayoga, i.e., lesser manifestation of a season (e.g. less rain in rainy season), thirdly, mithyayoga, i.e., unusual manifestation of a season (e.g., high temperature in winter season). The vitiation of air ([[vayu]]), water ([[jala]]), location ([[desha]]) and time (kala) may lead to epidemics (janapadodhwansha).

| Some diseases have a specific duration of pathogenesis. Five types of intermittent fevers (vishama jwara) are described based on frequency and time of manifestation viz. continuous (santata), two times in a day (satata), alternate day (anyedyushka), every third day (tritiyaka), and every fourth day (chaturthaka). | | Some diseases have a specific duration of pathogenesis.
