Fowl pox is an infectious disease that slowly spreads in birds. This virus specifically spreads in birds due to injured skin on the face, comb, and wattle. It has two types, one is dry (Cutaneous) and the other is wet (Diphtheritic). The mortality rate is lower but there is a great loss of egg production in this disease. Dry or cutaneous fowl pox usually appears on the face, comb, wattle, and other bare parts of the body. In wet pox, there are yellow lesions inside the mouth. Dead birds should be buried and diseased birds should be separated from healthy ones.
