title: [Age distribution of the incidence and immune structure of the pediatric population in epidemic parotitis].
abstract: An increase in the incidence of epidemic mumps among children is observed at 1 year, the highest incidence is found in the age group of 3--4 years which clearly correlates with the immunological status of the examined children. Antihemagglutinins to epidemic mumps virus have been found in 76.3% of infants at the age of 0 to 3 months, the minimal number of seropositives (36.2%) is observed at 7--9 months of age. Beginning at 10 months of age the percentage of seropositives increases reaching maximum (92.4--94.2%) in the age group of 6--7 years, after which the immune portion reaches stable 90.0%. The optimal age for vaccination is believed to be 1 year.
