SANZ MORENO, Juan Carlos et al. Evolution of Measles, Rubella and Mumps from the Third Seroepidemiological Survey in the Autonomous Region of Madrid, Spain. Rev. Esp. Salud Publica [online]. 2009, vol.83, n.5, pp.625-637. ISSN 2173-9110.

In this study results against measles, rubella and mumps obtained in the III Sero-epidemiological Survey of the Autonomous Region of Madrid, performed in 1999-2000, were related to the posterior evolution of these diseases in this Region. The prevalence of antibodies against measles, rubella and mumps was >90%, >95% and <90 %, respectively. Despite of the good results obtained for rubella and measles, in 2005 and 2006 two important outbreaks of these diseases occurred in Madrid. The rubella outbreak in 2005 (450 cases) affected especially to immigrants of both sexes (mainly from Central and South America) and Spanish adults males. The 2006 measles outbreak (174 cases) was imported, a high proportion of cases were adults and most of the patients were unvaccinated. No differences according to sex were observed. In Madrid mumps virus circulation has continued from 1999 to present. Two epidemic waves in the periods 2000-2001 and 2006-2007 have been detected. During 2006-2007, an important proportion of cases showed antecedents of vaccination. Each one of these three diseases has typical characteristics. However, the three has in common the change in the age of apparition, with a growing frequency of cases among young adults.
