RESUMEN
Fundamentos El primer caso confirmado de gripe pandémica (H1N1) 2009 adquirida en la Comunidad de Madrid (CM) se detec-tó el 20 de mayo, siendo el caso índice del primer brote escolar de la CM. Los objetivos son describir los brotes escolares ocurridos en la primavera de 2009, las medidas de control implementadas, así como el inicio de la transmisión comunitaria de este virus en la región. Métodos:
Estudio observacional descriptivo de los brotes esco-lares de gripe pandémica (H1N1) 2009 ocurridos en la CM entre el 20 de mayo y el 27 de junio de 2009, y de los casos totales estudiados en ese periodo. Se utiliza la definición de agrupación de casos de gri-pe adoptada a nivel nacional (3 o más casos). Se analizan los datos clínicos, epidemiológicos y microbiológicos de los casos.Resultados:
Se investigaron 1.349 casos asociados a 77 centros escolares de la CM con tres o más casos de gripe notificados durante la primavera de 2009, 47,4% del total de casos en ese periodo (n=2.844). Se detectaron 36 brotes en Leganés (más de un tercio de los centros del municipio), generando las mayores tasas de inciden-cia acumulada en la Zona Básica de referencia. Se detectaron dife-rencias en la sintomatología según la edad. Se analizaron 949 mues-tras por RT-PCR, resultando positivas 555 (58,5%).Conclusiones:
La transmisión del virus pandémico en la CM ocurrió de manera sostenida durante la primavera de 2009 a conse-cuencia de los brotes en centros escolares, significando el inicio de la transmisión comunitaria en España(AU)ABSTRACT
