In 2000, the circulation of indigenous measles was interrupted in Catalonia as a result of the activities of the elimination programme introduced in 1991. However, various transmission chains occurred in the indigenous population after the introduction of an imported case, and this caused a total change in the existing situation of elimination. .
The objective of this study was to analyze the epidemiological and clinical characteristics of the measles outbreak in Catalonia in 2006. Cases reported between August 28 2006 and July 8 2007 were collected. Cases were microbiologically confirmed by determination of measles-specific IgM and/or detection of the viral genome in urine samples.
A total of 381 cases of measles were confirmed, representing an incidence of 6.6 per 100,000 inhabitants. Laboratory confirmation was made in 87.1% of the cases and all specimens sequenced belonged to the D4 genotype. A total of 89.5% of the cases occurred in non-vaccinated people, above all in infants aged <16 months.
