title: A deterministic model for measles.
abstract: A deterministic model of recurrent epidemics is constructed using a non linear relationship between infection rate and number of contacts. Epidemic waves which are not damped are predicted and a relationship between community size and the period of recurrence is established. A possible explanation of measles outbreaks is suggested.
