Материалы международной конференции 2013, Т. 3, № 2 Since 1982, MMR vaccinations against measles, mumps and rubella have belonged to the national vaccination program in Finland. <...> A goal of these vaccinations was to eliminate all the three diseases. <...> For monitoring a progress of this goal an enhanced surveillance of measles, mumps and rubella was started along with the MMR vaccinations. <...> The active investigations of suspected measles, mumps and rubella cases showed a rapid decline in the incidence of all the three diseases soon after the launchment of the nationwide MMR vaccinations. <...> The enhanced surveillance also revealed that clinical diagnosis is not always reliable, particularly when measles, mumps or rubella is suspected in vaccinated individual. <...> The high MMR vaccination coverage was reached in the end of 1980s and indigenous measles, mumps and rubella were eliminated by the mid of 1990s from Finland. <...> Therefore, case-based laboratory surveillance and molecular epidemiological investigations became necessary to provide the required data in the elimination setting. <...> Molecular epidemiological characterization of sporadic cases has helped to identify the sources of imported cases and revealed that different genotypes of these diseases were imported over time to Finland. <...> In general, imported cases have not spread in the population, besides year 2011 when two clusters of import-related cases of measles were diagnosed. <...> The two separate clusters were caused by the D4 genotypes of measles virus, imported from other European countries; while two other imported measles cases in the same year were caused by other genotypes (D8 and G3) of measles virus. <...> Enhanced laboratory surveillance and molecular epidemiological investigations of all measles, mumps and rubella viruses are indispensable for following and assuring the achieved elimination in Finland. <...> CO-CIRCULATION AND MACRO-EVOLUTION OF POLIOVIRUSES AND OTHER ENTEROVIRUSES OF SPECIES C F.
