An animal infected with the pigeon pox virus may experience symptoms such as dehydration,
uveitis and vision problems, reduction in egg production and behavioural differences. Such animals are described as quiet and fluffed. Some of the infected animals show yellow and roundish nodules with a diameter of 0,5 – 1,0 cm under the eyelids, the beak and mouth. Lesions under the wing, the nasal area and the mouth commissure usually appear after a period of 10 – 12 days. These symptoms are usually divided into two main forms. The skin and mucous progression. Some experts even suggest a division into up to 5 different categories. The animal will generally recover from the infection within 6 weeks and the virus is only on very rare occasions lethal. == Diagnosis ==
