RESUMO
Introducción: La gripe es una enfermedad mundialmente vigilada a través de las redes centinela (RC) que predicen el comportamiento epidemiológico y comunican los datos clínicos y virológicos. Objetivos: Evaluar la rentabilidad de las muestras respiratorias pediátricas en la RC de las Islas Baleares en las últimas 5 temporadas gripales. Material y pacientes: Se tomó un frotis faríngeo para cultivo vírico de los pacientes que cumplían los criterios de gripe. Se inocularon las muestras en la línea celular MDCK. Se revisaron los datos epidemiológicos de cada paciente con cultivo positivo para los virus gripales A y B. Resultados: Durante el período de estudio se analizaron 338 frotis faríngeos de la RC. De éstos, 65 (19,3%) pertenecían a menores de 14 años. El 44,6% de estas muestras fueron positivas frente al 39,1% de las muestras de adultos. El virus gripal A se aisló en 24 muestras pediátricas (82,7%) y el virus gripal B se aisló en 5 muestras (17,3%). La edad media de los pacientes positivos de la RC fue de 8,5 años. En el grupo de 0 a 4 años sólo fueron positivos 3 pacientes (10,3%) y en el grupo de 5 a 14 años fueron positivos 26 pacientes (89,7%). Conclusiones: A pesar de que los pediatras sólo representan el 22% de los médicos de la RC y aportan el 19,3% de las muestras, el porcentaje de positividad y rentabilidad de éstas es superior al de la población adulta (AU)
Introduction: Influenza disease is subjected to surveillance by national networks (RC) that predict the epidemic behaviour by reporting clinical and virological data. Objectives: To evaluate the effectiveness of the paediatric respiratory samples in the Balearic Islands RC in the last five epidemic seasons. Material and patients: A breath sample was taken from paediatric patients in the RC who had flu symptoms. The samples were inoculated in the MDCK cell line. We reviewed the epidemiological data of patients with a culture positive to influenza A and B. Results: A total of 338 pharyngeal swabs from the RC were analysed during the study period. Of these, 65 (19.3%) belonged to <14 years old patients, and 44.6% of the samples were positive as opposed to 39.1% of adult respiratory samples. The influenza A virus was isolated in 24 paediatric samples (82.7%) and the influenza B virus in 5 (17.3%). The mean age of the paediatric patients of the RC who were positive was 8.5 years. Only 3 patients in the 04 year old group were positive (10.3%) and 26 patients (89.7%) in the 514 years old group. Conclusions: In spite that paediatricians represented only 22% of the RC doctors and obtain the 19.3% of all respiratory samples, the percentage and effectiveness of these is higher that obtained in the adult population (AU)
