title: [Incidence of epidemic parotitis in different countries].
abstract: The authors analyzed the incidence of epidemic parotitis in various countries in 1960--1969 on the basis of the data published by the WHO. It can be supposed that there was no significant difference in the morbidity in various countries and that discrepancy in the official data of individual countries was apparently caused by the errors in recording. In the majority of the countries morbidity curve was fluctuating in character with a 4--5-year periodicity. In the countries of the northern hemisphere the greatest number of cases occurred in spring, and in the southern--in autumn. Monthly distribution of cases during the years with a high and low morbidity level displayed no significant changes.
