HPAI
Highly Pathogenic Avian Influenza (HPAI) is a subtype of avian influenza that has the potential to cause severe disease and death in birds. It is characterized by its high mortality rate and the ability to spread rapidly among poultry populations. HPAI viruses are classified into different subtypes based on the surface proteins hemagglutinin (HA) and neuraminidase (NA). The most commonly reported subtypes are H5N1, H5N8, and H7N9. HPAI viruses can infect a wide range of bird species, including domestic poultry, wild birds, and even mammals, although the latter is less common.
The transmission of HPAI occurs through direct contact with infected birds, contaminated surfaces, or through the
