Marek disease: Introduction
Marek disease: A viral disease that affects poultry - it is very contagious and is a herpes virus. The virus tends to affect the nerves and cause tumors in internal organs. Poultry may be unable to lay eggs or may even die. Young birds are more susceptible than older birds with death most common between the ages of 8 and 20 weeks. The virus may attack the nervous system and result in paralysis or it may attack the visceral system and cause tumors in the internal organs. Some birds may die without any obvious symptoms.

Treatments for Marek disease
- There is no treatment - infected birds should be destroyed promptly in a humane way and other birds should be monitored for signs of the infection. Vaccinations are used routinely in commercial operations as a preventative measure although birds may still develop the infection if they are vaccinated. The development of genetically resistant poultry is also being used to control the virus.
