Chicken Anemia Virus (CAV) is a virus that primarily affects chickens, leading to a disease known as Chicken Anemia. It is a member of the Circoviridae family and is known to cause immunosuppression in infected birds, making them more susceptible to other diseases. The virus is transmitted through direct contact with infected birds or contaminated environments. Infected chickens may show symptoms such as anemia, lethargy, and reduced growth rates. The disease can have significant economic impacts on poultry farms due to increased mortality and decreased productivity. Vaccination and good management practices are essential for controlling the spread of CAV.
