What Are the Symptoms of Bird Flu?
Bird flu, or avian influenza (AI), is a contagious viral infection caused by influenza type A viruses that primarily affect birds but can, in rare cases, infect other species, including humans. The most serious strains are Highly Pathogenic Avian Influenza (HPAI), such as H5N1 and H5N8, which can cause rapid death in poultry flocks and even pose risks to public health.
