Abstract

Review of literature on the seasonality of measles in India reveals that measles occur throughout the year with peaks around March, while October-November are the low transmission months. The epidemics of measles however, occur any time during the year. Nevertheless, measles vaccination campaigns are carried out in India in the Month of March to increase the vaccine coverage levels. Being the low transmission season, October and November may be more appropriate for undertaking measles campaigns in India.
