Mumps: A case report

The widespread of mumps and its medical and social significance determine the relevance of further study of the etiology, epidemiology, diagnosis, treatment, and prevention of mumps infection. Despite the lack of mortality, the possible occurrence of complications that affect the suppression of male reproductive function makes mumps a priority. Official statistics show the annual incidence of mumps in the Russian Federation, estimated in hundreds of cases up to several thousand (2017–2018). The continued spread of mumps is associated with violations of immunization regimens, underestimation of the unvaccinated population or unreliability of the reported data, introduction of new viral genotypes capable of bypassing vaccine immunity, and natural weakening of post-vaccination immunity.

The presented clinical case refers to an outpatient case of mumps in a 53-year-old man with a delayed diagnosis despite the typical clinical manifestations. The clinical case demonstrates the lack of awareness of outpatient practitioners about the manifestations of mumps. The causes of mumps in older age groups and possible ways to solve the problem are discussed.
