Pigeon pox is caused by a virus that is spread by mosquitoes and dirty water but not in droppings. Pox viruses are specific to the animal.Pigeons can develop chicken pox although in a milder form.An infected pigeon is not infectious to humans.
The pigeon pox virus attacks the skin and mucous membrane cells about 4 to 14 days after exposure.There is an internal and an external form of pox.The mucous membrane form can be indistinguishable from canker like, evil smelling deposit in the beak and throat cavities.In the internal form an infected pigeon will have crusty lesions on its unfeathered skin,nostrils and ceres, especially around the eyes around the beak on the feet and around the anus.It is possible for a pigeon to have both forms of the disease at the same time.
Once in the blood, the virus quickly infects the liver and bone marrow,reinfecting the blood.The pox organisms then migrate to the skin and mucous membranes, forming lesions that are breeding grounds for many bacteria.
Except to monitor the pox lesions. in general,the infection should be left to its natural process.Lesions around the eyes and in the mouth may interfere with seeing and eating and required medical attention,but they should dry up and disappear in a few days.
There are vaccines for pox that work with varying degrees of efficiency , These vaccines are not available in India as treatment i have used the Pox cream from DAC which is found very effective , I also apply a paste of Neem oil, Salt and turmeric powder in the lesions
