What are the main causes of Avian Influenza?

Direct contact with infected poultry, such as through handling or preparing them for consumption, is the most common route of transmission to humans.

While rare, the influenza A virus can sometimes be transmitted through consuming undercooked poultry or eggs from infected birds, posing a significant risk.
