Epidemic mumps among students

The purpose of this work was to study the spread of epidemic parotitis among students of 9-10th grades of secondary schools and vocational schools. Analysis of data on morbidity in Saratov from 1979 to 1983 showed a relatively high morbidity of epidemic mumps among the general population and students of schools and vocational schools in particular. The situation changed dramatically after 1984, when the morbidity rate among the general population decreased sharply, and cases of parotitis among students of vocational schools and senior high schools became sporadic, in some years not observed at all. There is reason to believe that these changes in the morbidity rate were the result of mass immunization against mumps in the most susceptible age groups of the population.
