Abstract
In 1997, a high-pathogenicity H5N1 avian influenza virus caused serious disease in both man and poultry in Hong Kong, China. Eighteen human cases of disease were recorded, six of which were fatal. This unique virus was eliminated through total depopulation of all poultry markets and chicken farms in December 1997. Other outbreaks of high-pathogenicity avian influenza (HPAI) caused by H5N1 viruses occurred in poultry in 2001 and 2002. These H5N1 viruses isolated had different internal gene constellations to those isolated in 1997. No new cases of infection or disease in man due to these or other H5N1 viruses have been reported. This paper provides an overview and chronology of the events in Hong Kong relating to avian influenza, covering the period from March 1997 to March 2002. Resumen Influenza Aviar en Hong Kong 1997–2002. En 1997, un virus de influenza aviar altamente patógeno del serotipo H5N1 causó un brote de la enfermedad en humanos y aves en Hong Kong, China. Se reportaron dieciocho casos en humanos, de los cuales seis causaron el deceso de los pacientes. Este virus especial fue eliminado de la población mediante la despoblación de todas las aves de los mercados de aves y granjas avícolas en Diciembre del 1997. En los años 2001 y 2002 ocurrieron otros brotes de la enfermedad causados por virus altamente patógenos del virus de influenza aviar del serotipo H5N1. Los virus aislados presentaron diferencias a nivel del genoma cuando fueron comparados con los virus aislados en el brote del año 1997. No se han reportado nuevos brotes en humanos causados por estos u otros virus del tipo H5N1. Este trabajo revisa la cronología de los eventos ocurridos en Hong Kong en los brotes de influenza en el periodo comprendido entre el mes de Marzo de 1997 al mes de Marzo del 2002.
