Fowl pox virus is a viral infection that primarily affects birds, especially chickens and turkeys. It is caused by a member of the Poxviridae family and is characterized by the appearance of lesions on the skin and in the mouth. The virus spreads through direct contact, insect bites, or contaminated equipment. Infected birds may show symptoms such as lethargy, loss of appetite, and difficulty breathing. While fowl pox is generally not fatal, it can lead to secondary infections. Vaccination is available and is an effective way to prevent the disease in poultry populations.
