Chicken Infectious Anemia Virus (CIAV) is a virus that primarily affects young chickens, leading to anemia and immunosuppression. It is a member of the Anemia virus family and can cause significant health issues in poultry, particularly in flocks that are not vaccinated. The virus spreads through direct contact, contaminated equipment, and the environment. Infected birds may show symptoms such as lethargy, pale combs, and reduced growth rates. CIAV can also lead to increased susceptibility to other diseases due to its impact on the immune system. Effective management includes vaccination and maintaining biosecurity measures to prevent outbreaks.
