Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This review analyzed the epidemiology and impact of HPAI (H5N1 and H5N8) in migratory birds and poultry in Kazakhstan, with a special focus on outbreaks from 2005 to 2024. A comprehensive bibliographic analysis of publications on avian influenza in Kazakhstan over the past 20 years was performed. This review mainly included epidemiological studies of virus detections in wild and poultry in Kazakhstan. Migratory wild birds, in particular, played a key role in the spread of the virus. An analysis of the migration chronology of HPAIV-carrying birds prior to their entry into Kazakhstan was conducted, as well as a comparative analysis of seasonal and water landscape characteristics in previous habitats. The complexity and risks associated with the virus, together with the limited number of current scientific studies in Kazakhstan, require further research to reduce its impact on animals and the ecosystem as a whole.
