Avian influenza, commonly known as bird flu, is a viral infection that primarily affects birds. Among the various subtypes, the H9N2 avian influenza virus has gained attention due to its ability to infect a wide range of bird species and occasional transmission to humans.
In poultry, H9N2 infections can range from asymptomatic to severe, depending on various factors such as the bird species, age, and the presence of other pathogens. Common symptoms in birds include respiratory distress, reduced egg production, and a drop in feed consumption. In humans, symptoms are similar to those of other influenza viruses and may include fever, cough, sore throat, and difficulty breathing.
