Ongoing rubella outbreak in Bosnia and Herzegovina, March-July 2009--preliminary report.

Between 24 March and 31 July 2009, 342 clinically diagnosed cases of rubella were notified in five municipalities in Republika Srpska, Bosnia and Herzegovina. Fourteen cases were laboratory-confirmed by positive IgG against rubella virus. Four virus isolates were obtained and identified as genotype 2B strains, with one isolate differing by a single mutation in the region of the E1 gene. This ongoing outbreak revealed gaps in the immunisation programme during the war in BiH (1992-1995) and highlights the need to revise legislation to permit immunisation of children above 14 years of age with measles, mumps, rubella (MMR) vaccine and to introduce supplemental immunisation activities.
