[Outbreak of measles in the population of Spanish origin in North Madrid].

After being virtually eradicated in Europe, thousands of cases of measles in the population of Spanish origin have appeared in the last 3 years. We describe the cases diagnosed in the north of Madrid between January and June 2011. A total of 22 cases are reported, 18 of them grouped in 2 outbreaks (2 nurseries). The primary attack rate was 29% in the main outbreak. All cases were in unvaccinated patients (median = 14 months). Genotype D4 was predominant (95%). There was a 45% complication rate and 45% were admitted to hospitals. The Public Health Service recommended isolating cases and vaccinating susceptible contacts in advance. Health Centres established a specific protocol to respond to suspected cases. The Measles vaccination has been brought forward from 15 to 12 months in Madrid. Measles is a re-emerging disease in Europe. The coordinated management between public health and health facilities is essential to limiting outbreaks.
