In a recent study conducted by the School of Public Health at the Faculty of Medicine, HKU, it has been confirmed that H5 avian influenza viruses continue to persist in wild bird populations. This discovery further aggravates the spread of H5 viruses, resulting in an expansion of their geographic and host range. Moreover, it increases the likelihood of genetic recombination and evolution. The research team emphasizes the urgent need for improved influenza virus control strategies in order to mitigate the risk of future epidemics. These findings have been published in the prestigious international journal “Nature”.

For this study, the team extensively analyzed over 10,000 complete viral genomes and evaluated epidemiological data collected from 2005 to 2022 by the Food and Agriculture Organization of the United Nations and the World Organization for Animal Health. These efforts aimed to uncover the origins and trends of highly pathogenic H5 bird flu outbreaks.

The latest research from the School of Public Health, Faculty of Medicine, HKU, confirms that H5 avian influenza viruses persist in wild bird populations, which exacerbates the spread of H5 viruses, expanding their geographic and host range, and increasing the possibility of genetics. recombination and evolution. The research team is of the opinion that influenza virus control strategies need to be improved in order to reduce future epidemics. This research has been published in the authoritative international journal “Nature”.

The team used epidemiological data collected by the Food and Agriculture Organization of the United Nations and the World Organization for Animal Health between 2005 and 2022 and analyzed more than 10,000 complete viral genomes to reveal the origins and trends of highly pathogenic H5 bird flu outbreaks.
