How quickly does Marek’s disease progress?
Impacts. Often results in death or severe production loss in both layer and meat chickens. In meat chickens, the disease can develop within 3-4 weeks. In layers, most deaths occur between 12 and 24 weeks of age however, in some cases, the disease may not appear until later in life.
How long will a chicken live with Marek’s disease?
Mortality in an affected flock typically continues at a moderate or high rate for quite a few weeks. In ‘late’ Marek’s the mortality can extend to 40 weeks of age. Affected birds are more susceptible to other diseases, both parasitic and bacterial.
How do you test for Marek’s disease?
PCR of blood or fresh tissue is the preferred test method for confirmation of infection. Histopathology usually shows typical lymphoproliferative lesions which will suggest infection, which can then be confirmed by PCR.
Where does Marek’s disease come from?
Over the past fifty years, Marek’s disease—an illness of fowl—has become fouler. Marek’s is caused by a highly contagious virus, related to those that cause herpes in humans. It spreads through the dust of contaminated chicken coops, and caused both paralysis and cancer.

Is Marek’s disease in chickens contagious?

What do I do if my flock has Marek’s?
Separate a sick hen from the flock. If she has Marek’s, kill her humanely and take action to limit damage by vaccinating and observing the flock closely for others that may develop paralysis or other symptoms. It takes two weeks for the chicken to develop immunity.
