RESUMEN

Durante el siglo pasado se presentaron tres principales pandemias por el virus de influenza que dejaron un devastador número de muertes de seres humanos. La reciente propagación del virus influenza A H5N1 en aves domésticas y silvestres ha incrementado la amenaza de la infección en seres humanos con el subtipo H5N1. El virus se detectó por primera vez en China en 1996, donde causó la muerte de algunos gansos. Se propagó rápidamente a Europa y África, causando la muerte de miles de aves y de más de 100 personas. La zoonosis por este virus altamente patógeno H5N1 ha causado una alarma global por la posibilidad de que evolucione y surja una nueva cepa de virus para humanos. La vigilancia sobre salud, en la mayoría de los países está enfocada en la reducción de la morbilidad y mortalidad, y la OMS ha convocado a todos los países para que tomen medidas para su preparación, para identificar las necesidades prioritarias y para desarrollar un Plan Nacional de Prevención en caso de pandemia por influenza. El éxito de estas acciones dependerá de los avances de cada miembro de la comunidad internacional.
