Characteristics of the epidemiological situation of mumps in the world at the present stage

Relevance. The socio-economic significance of mumps is determined by complications after a previous infection, affecting reproductive function, what entails economic and demographic losses. An important problem today remains the fact that despite high coverage with preventive vaccinations outbreaks of mumps are recorded among children and young adults. Aim. Analyze the epidemic situation with epidemic parotitis in the world according to various literary sources and evaluate measures to control and combat this infection. Conclusions. Outbreaks of mumps have been reported among religious and ethnic groups. Outbreaks were often recorded in organized student and military groups, mainly among persons twice vaccinated. The most affected by the mumps virus were adolescents and young adults, mostly males. Several researchers have shown the possibility of using a third dose of MMR vaccine to control an outbreak, but its short-term effect does not provide conclusive evidence for rethinking two-dose mumps immunization. © Turaeva NV et al.
