Some coronaviruses involved in this condition are considered to be bovine coronaviruses (or closely related thereto); others are avian coronaviruses closely related to infectious bronchitis virus. The infection is seen in turkeys and sometimes pheasants. Morbidity is close to 100% and mortality is 5-100%. Transmission is lateral with birds and faeces, with rapid spread. The course of the disease is about 2 weeks and birds then remain carriers for months. The viruses survive in frozen faeces for months.
