Mumps is a notifiable disease in all the countries in the region, except for Germany.
Following the introduction of the measles-mumps-rubella (MMR) vaccine in the national immunisation programmes in the early 1980s, mumps has become a rare disease in all the Nordic countries. This is mainly as a result of high immunisation coverage during several years. In contrast, lower immunisation coverage in areas of the eastern part of the region results in an unstable situation with periodic outbreaks. The immunisation coverage in the eastern part of the area has greatly improved during the last few years. A currently ongoing outbreak of mumps in Latvia is primarily involving young people.
Non-immune children are most at risk for contracting mumps, but outbreaks have also been observed in young adults.
Vaccination with mumps mono-vaccine or as a part of the MMR-vaccine, is the best measure to decrease the incidence and subsequent outbreaks of mumps. In all countries in the region mumps vaccine is given as part of the national immunisation programmes. Except for Russia, all countries in the region now use the MMR-vaccine.
