A survey of school children suffering from chronic secretory otitis media over an eight-year period compares the incidence in a city area and country area and various areas within the city. A factor in the causation of the condition appears to be poor living conditions and air pollution. An increase in the incidence occurred in both areas following a winter in which there was an exceptional incidence of influenza.
