Abstract
The H5N1 virus currently circulating is continuing to evolve, and it has already resulted in the extension of its host and geographical range. It is likely that H5N1 will become a global problem for the poultry industry. How many of the recent H5N1 changes observed have been induced by changing patterns in poultry raising? A change in attitude on the use of high-quality vaccines is a change that would drastically help in the control of the current epidemic in the poultry industry. This article provides an overview of the changing properties that have been observed during the current H5N1 outbreaks. Cambios en la epidemiología y ecología de los virus de influenza aviar H5N1 de alta patogenicidad. El virus H5N1 circulando actualmente continúa evolucionando, dando como resultado variaciones en cuanto a huésped y área geográfica. Es probable que el virus H5N1 se convierta en un problema global para la industria avícola. Cuantos de los cambios observados recientemente en el virus H5N1 han sido inducidos por cambios en los patrones de cría de las aves domésticas? Un cambio de actitud sobre el uso de vacunas de alta calidad es un cambio que ayudaría drásticamente en el control de la epidemia actual en la industria avícola. El presente artículo proporciona una revisión de los cambios observados durante los brotes actuales del virus H5N1. Abbrevations: HPAI = highly pathogenic avian influenza; HP = highly pathogenic; IVPI = intravenous pathogenicity index; TCID50, = tissue culture infectious dose 50Keywords
