Avian Fowl Pox is a viral disease that causes canker-like sores affecting the skin, mouth and throat. The disease is best controlled through vaccination. Control of the disease can be difficult since mosquitoes spread Fowl Pox between birds and are secondary carriers of the disease. There are two forms of Fowl Pox; Dry or Cutaneous Pox affects the skin, and Wet or Diphtheritic Pox primarily affects the mouth and throat. Particularly virulent strains can cause a systemic form affecting internal organs, though this is less common.
Most birds, including:
Where: Worldwide; common anywhere poultry is raised; in particular confined populations during winter and spring
When: Any age
Why: Virus - DNA avian pox
Dry Pox Symptoms:
Wet Pox Symptoms:
Treatment: None. Cull birds that show symptoms. The disease is slow spreading, so vaccination can protect birds that have yet to show signs, and can prevent a large outbreak.
Vaccine: Yes (click here for more information)
Pesticides: Useful to control mosquito populations in closed flocks.
Also Known As:
Affects: Skin (dry pox); mouth and upper respiratory tract (wet pox)
Clinical Diagnosis: Identified by the presence of wart-like bumps typical of fowl pox. Can be confirmed by testing scabs for the virus, but this is usually unnecessary.
Diseases with similar symptoms:
Duration of symptoms: prolonged and slow duration; affects a bird for 3 to 5 weeks
Incubation: 4 to 10 days
Morbidity: 10 to 95%
Mortality: Low(<10%) for dry pox, to moderate(10 to 49%) for wet pox
Transmission to people: No.
