Since our last update of 11 March 2004, one new and fatal human case has been reported, which brings the total to 34 cases and 23 deaths. The number of human cases of avian influenza A (H5N1) reported appears to be stable. Two Asian countries have reported human cases from this subtype: Viet Nam (22 human cases and 15 deaths) and Thailand (12 human cases and 8 deaths). Epizootics have been reported from this subtype among birds in 8 Asian countries. Other countries have reported flu outbreaks in birds, but these do not correspond to highly pathogenic subtype H5N1. Desde nuestra última actualización (11 de marzo de 2004), se ha notificado 1 caso nuevo fatal de influenza aviar en humanos, lo que hace un total de 34 casos y 23 muertes. Aparentemente el número de casos humanos notificados se ha estabilizado, siendo dos países asiáticos los que han notificado casos en humanos por este subtipo: Vietnam (22 casos humanos con 15 muertes) y Tailandia (12 casos humanos con 8 muertes). En 8 países asiáticos se han notificado epizootias por este subtipo en diversas especies de aves. Otros países han notificado brotes de influenza en aves, pero no corresponden con el subtipo H5N1 altamente patógena.
