[Measles in France].

From January 2008 to May 2012, over 22,000 cases of measles were reported in France. The highest incidence rate was observed in children below one year of age. Over 50% of cases were reported in young adults. Almost 5,000 patients were hospitalised including 1,023 with severe pneumonia, 27 with encephalitis and/or myelitis : 10 died. This situation is linked to insufficient and heterogeneous vaccination coverage with pockets of susceptible people allowing virus circulation. Although the vaccine coverage in children has now improved for both doses, the issue of convincing young susceptible adults to catch up for measles vaccination remains critical, if the elimination target is to be met, and in order to protect the most vulnerable population unable to benefit from this vaccination (children below 1 year, immunodeficient people, pregnant women).
