Avian influenza is a highly contagious viral disease that occurs primarily in poultry and wild water birds. It is either high or low pathogenic (HPAI/LPAI) depending on the molecular characteristics of the virus involved and its ability to cause disease and mortality in chickens.
Poultry infected with LPAI viruses may show mild signs of the disease or none at all. Infections caused by HPAI are more severe and may even cause death. Both HPAI and LPAI can spread easily and quickly through poultry flocks. Therefore, the implementation of stringent biosecurity measures in farms is essential. Moreover, LPAI viruses can mutate into highly pathogenic strains, which highlights the importance of prompt outbreak management. ...
Avian influenza can be transmitted from animals to humans mainly in two ways:
Latest
In April 2024, EFSA and ECDC issued a report discussing the drivers for a potential pandemic of avian influenza currently in circulation worldwide. The report focuses on events such as reassortment, mutation and adaptation of avian influenza viruses to mammals, including humans.
The experts also identified a number of risk mitigation measures to be implemented under a One Health approach at national and EU level to reduce the risk of the virus evolving. ...

Avian influenza can be transmitted from animals to humans mainly in two ways:
- Directly from birds or from contaminated environments
- Through an intermediate host, such as a pig
