IMMUNIZATION EFFECT ON EPIDEMIC PAROTITIS OCCURRENCE
A very high epidemic parotitis occurrence had been registered before vaccination started in the Republic of Belarus — the average annual value for many years was determined as 269.5 per 100 000. The scheme stipulating one vaccination introduced from 1980 and the scheme stipulating two vaccinations introduced from 2000 allowed reduce the morbidity rate markedly. That parameter was 102.4 times lower in 2006—2010 as compared with the same in the pre-vaccination period. The laboratory diagnosis introduction favored the epidemic parotitis genuine cases differentiation with other salivary glands diseases. The laboratory examination of 101 patients suspected for epidemic parotitis carried out in the first half of 2011 confirmed the disease viral etiology for 36 (35.6%) persons. The data obtained evidence about expediency of registering the epidemic parotitis cases confirmed by laboratory analysis.
