“…This investigation of measles in the Irish traveller community identified 156 cases in travellers and 17 cases in general community contacts of traveller cases occurring over a 3-month period across 17 different travellers sites in most regions of England. International spread to Norway was also observed [1,15]. None of the cases were vaccinated, consistent with the low level of vaccination uptake in this community [9].…”

Between 3 April and 18 May 2007, 21 confirmed cases of measles were reported in members of the Irish traveller ethnic group who attended a funeral in London, England. The Health Protection Agency conducted an investigation to determine the extent of this outbreak in order to inform prevention of future outbreaks. From 23 March to 30 June, 173 outbreak-associated cases from seven regions throughout England were identified; 156 cases were in Irish travellers and 17 were epidemiologically linked to cases in that community. In total, 124 cases were laboratory confirmed (IgM or RNA); none were vaccinated against measles. MMR vaccination was offered on traveller sites. Low vaccination coverage and the movement of traveller communities present particular challenges for measles elimination in Europe. We recommend parallel approaches to improve integration of Irish travellers within routine health services whilst offering targeted interventions to increase vaccine uptake in this marginalized community.

“…The MMR vaccine coverage data for the second dose is available for 16 year-olds (birth cohort 1993) and the coverage was 90% in the district of Old Oslo and 94% in Oslo as well as in rest of the country [10]. All measles cases identified during the last decade in Norway have been linked to importation from endemic areas or linked to other outbreaks in Europe [12,13]. The last outbreak in Norway before 2011 occurred in 2008 in an anthroposophical community, where the index case fell ill after returning from Austria [14].…”

“…The last outbreak in Norway before 2011 occurred in 2008 in an anthroposophical community, where the index case fell ill after returning from Austria [14]. In 2007, there was an outbreak among members of the Irish travelling community from England who were in Norway at the time [13]. Measles spread among unvaccinated children within the community, but no cases occurred in the local population.…”

This study describes 33 laboratory-confirmed cases of measles that occurred in Norway in 2011, mainly among unvaccinated children between seven months and 10 years of age. Laboratory testing included detection of anti-measles IgM- and IgG antibodies by enzyme-linked immunosorbent assay (ELISA) and molecular detection and characterisation of measles virus by polymerase chain reaction (PCR) and sequencing. Epidemiological data and genotyping revealed that the measles cases originated from eight separate importations, resulting in four outbreaks and four sporadic cases. Except for the first outbreak which affected 18 cases, limited secondary spread occurred in each of the three other outbreaks. The outbreaks were caused by measles virus genotypes B3, D4 and D9, whereas genotypes D8 and B3 were detected in the sporadic cases. This study highlights that genetic characterisation of measles virus is an essential tool in the laboratory surveillance of measles, especially in countries like Norway which are approaching the measles elimination goal. The investigation revealed that importation of measles resulted in subsequent transmission within Norway to non-vaccinated individuals, and twelve cases occurred in healthcare settings, involving both staff and children. The four cases detected among healthcare workers (HCWs) emphasised that the coverage of measles-mumps-rubella (MMR) vaccination among healthcare personnel needs to be improved and both primary and secondary vaccine failure was demonstrated in two fully immunised HCWs.

An outbreak of measles among a travelling community from England in Norway: a preliminary report

Abstract: Between 7 and 14 May 2007, Nasjonalt Folkehelseinstitutt (the Norwegian Institute of Public Health, NIPH) was notified of six cases of measles, all occurring in a group of families from England staying at camping sites in Norway.
