Epidemiological vigilance in Navarre (601,874 inhabitants) in 2006 included 34 diseases whose notification is compulsory and epidemic outbreaks. Notification is carried out on a weekly basis by the doctors from paediatrics, primary care and specialised care facing any suspicion of these processes, and is completed with microbiological diagnoses. In 2006 the incidence of influenza reached 16.8 cases per 1,000 inhabitants (Epidemic Index, EI: 0.46), showing a late seasonal peak (March) of low dimensions. The incidence of respiratory tuberculosis was 11.3 cases per 100,000 inhabitants, and that of non-respiratory tuberculosis was 2.3; both at similar levels to recent years. Seven cases of tuberculosis occurred in three aggregates amongst cohabitants, and another 7 in non-cohabiting persons resident in the same municipality. Six percent of the cases were coinfected with HIV, and 37% occurred in immigrants. The incidence of meningococcal disease rose to 19 cases (3.2 cases per 100,000 inhabitants; EI 1.46), all of them sporadic. Neisseria meningitidis serogroup B was isolated in 16 cases. There was one case of serogroup C, in a child who had received 3 doses of combined vaccine. In two cases (11%) death occurred. The incidence of legionnaire’s disease rose to 28 cases per 100,000 inhabitants (EI:4.88), due to a community outbreak that affected 146 people. Excluding this outbreak, incidence was similar to previous years (3.3 per 100,000 inhabitants). In August an outbreak of parotitis began, and 911 cases had been counted until the end of 2006; and it has continued during 2007. Eleven cases of malaria were registered, all imported. Notifications of toxic food infections has continued to fall (IE:0.48).
