Mumps outbreak in Jerusalem affecting mainly male adolescents

Abstract

From mid-September 2009 to 7 December 2009, 173 cases of mumps have been reported in the Jerusalem District. Most cases (82.1%) were male adolescents (median age 14.5 years) who are students in religious boarding schools. The majority of them (74%) are appropriately vaccinated for their age; 67% had received two doses of mumps-containing vaccine. An epidemiologic connection has been reported with visitors from New York, some of whom had recently had mumps.
